PMP 450 Installation Guide Safety and regulatory information

Safety and regulatory information

This section describes important safety and regulatory guidelines that must be observed by personnel
installing or operating PMP 450 equipment.

Important safety information

To prevent loss of life or physical injury, observe the safety guidelines in this section.

Power lines
Exercise extreme care when working near power lines.

Working at heights
Exercise extreme care when working at heights.

Grounding and protective earth
PMP 450 units must be properly grounded to protect against lightning. It is the user‘s responsibility to
install the equipment in accordance with national regulations. In the USA, follow Section 810 of the
National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow Section 54 of the Canadian
Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit,
mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for
grounding electrodes. Other regulations may apply in different countries and therefore it is
recommended that installation of the outdoor unit be contracted to a professional installer.

Powering down before servicing
Always power down and unplug the equipment before servicing.

Primary disconnect device
The AP or SM unit‘s power supply is the primary disconnect device.

pmp-0048 (September 2012) iv


External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to
the outdoor environment.

RF exposure near the antenna
Radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always
turn off the power to the PMP 450 unit before undertaking maintenance activities in front of the
antenna.

Minimum separation distances
Install the AP/SM so as to provide and maintain the minimum separation distances from all persons.

The minimum separation distances for each frequency variant are specified in Calculated distances and
power compliance margins on page 2-11.

Important regulatory information
The PMP 450 product is certified as an unlicensed device in frequency bands where it is not allowed to
cause interference to licensed services (called primary users of the bands).

Radar avoidance
In countries where radar systems are the primary band users, the regulators have mandated special
requirements to protect these systems from interference caused by unlicensed devices. Unlicensed
devices must detect and avoid co-channel operation with radar systems.

Installers and users must meet all local regulatory requirements for radar detection. To meet these
requirements, users must set the correct region code during commissioning of the PMP 450. If this is
not done, installers and users may be liable to civil and criminal penalties.

Contact the Cambium helpdesk if more guidance is required.

USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to implement special
features to prevent interference to radar systems that operate in the 5250-5350 and 5470-5725 MHz
bands. These features must be implemented in all products able to operate outdoors in the UNII band.
The use of the 5600 – 5650 MHz band is prohibited, even with detect-and-avoid functionality
implemented.

Manufacturers must ensure that such radio products cannot be configured to operate outside of FCC
rules; specifically it must not be possible to disable or modify the radar protection functions that have
been demonstrated to the FCC.

pmp-0048 (September 2012) v


In order to comply with these FCC requirements, Cambium supplies variants of the PMP 450 for
operation in the USA or Canada. These variants are only allowed to operate with region codes that
comply with FCC/IC rule.

PMP 450 Installation Guide Installation planning

Chapter 1: Installation planning

This chapter provides information to help the user to plan a PMP 450 network.

The following topics are described in this chapter:
Regulatory planning on page 1-2 describes how to plan PMP 450 links to conform to the regulatory
restrictions that apply in the country of operation.
Site planning on page 1-3 describes factors to be considered when choosing sites for the AP, SM and
accessories.
Grounding and lightning protection on page 1-6 describes how to plan for proper grounding and lightning
protection including cabling requirements and installation suggestions
Ordering components on page 1-13 details part numbers and descriptions of PMP 450 equipment

Conforming to the limits Installation planning

Regulatory planning

This section describes how to plan PMP 450 links to conform to the regulatory restrictions that apply in the
country of operation.

It is the responsibility of the user to ensure that the PMP product is operated in accordance with local
regulatory limits.

Contact the applicable radio regulator to find out whether or not registration of the PMP network is required.

Obeying Regulatory limits
The local regulator may restrict frequency usage and channel width, and may limit the amount of conducted or
radiated transmitter power.

Many countries impose EIRP limits (Allowed EIRP) on products operating in the bands used by the
PMP 450 Series. For example, in the 5.8 GHz band, these limits are calculated as follows:
In the 5.8 GHz band (5725 MHz to 5875 MHz), the EIRP must not exceed the lesser of 36 dBm or (23 + 10
x Log Channel width in MHz) dBm.

Some countries (for example the USA) impose conducted power limits on products operating in the 5.8 GHz
band.

Conforming to the limits
Ensure the system is configured to conform to local regulatory requirements by setting the appropriate Region
Code setting on the APs and SMs in the network. When using connectorized APs with external antennas, the
regulations may require the maximum transmit power to be reduced. To ensure that regulatory requirements
are met for connectorized installations, refer to Compliance with radio regulations on page 2-13.

PMP 450 devices do not operate in the 2.4 GHz or UNII (5150-5250, 5250-5350, 5470-5725 MHz) bands.

1-2 pmp-0048 (September 2012)


Site planning

This section describes factors to be taken into account when choosing sites for the AP or SM, power supplies,
CMM4 (if applicable) and GPS antenna (if applicable).

AP or SM site selection
When selecting a site for the AP or SM, consider the following factors:
Height and location to ensure that people are kept away from the antenna; see Minimum separation
distances on page v.
Height and location to achieve the best radio path.
Ability to meet the requirements specified in Grounding and lightning protection on page 1-6.
Aesthetics and planning permission issues.
Cable lengths; see Maximum cable lengths on page 1-3.
The effect of strong winds on the installation; see Wind loading on page 1-4.

Power supply site selection
When selecting a site for the AP or SM power supply, consider the following factors:
Indoor location with no possibility of condensation.
Availability of a mains electricity supply.
Accessibility for viewing status indicator and connecting Ethernet cables.
Cable lengths; see Maximum cable lengths on page 1-3.

Maximum cable lengths
When installing PMP 450 Series APs or SMs, the maximum permitted length of the copper Ethernet interface
cable is 100 m (330 ft) from AP/SM to their associated power supplies or CMM4.

pmp-0048 (September 2012) 1-3

Wind loading Installation planning

Wind loading
Ensure that the site will not be prone to excessive wind loading.
Antennas and equipment mounted on towers or buildings will subject the mounting structure to significant
lateral forces when there is appreciable wind. Antennas are normally specified by the amount of force (in
pounds) for specific wind strengths. The magnitude of the force depends on both the wind strength and size of
the antenna.

Calculation of lateral force (metric)
The magnitude of the lateral force can be estimated from:
Force (in kilogrammes) = 0.1045aV2

Where: Is:
a surface area in square meters

V wind speed in meters per second

The lateral force produced by a single PMP 450 at different wind speeds is shown in Table 2 Lateral force -
metric and Table 3 Lateral force - US.

Capabilities of the PMP 450 Series
The structure and mounting brackets of the AP are capable of withstanding wind speeds up to 190 kph (118
mph). Ensure that the structure to which the AP is fixed to is also capable of withstanding the prevalent wind
speeds and loads.

The structure and mounting brackets of the SM are capable of withstanding wind speeds up to 190 kph (118
mph). Ensure that the structure to which the SM is fixed to is also capable of withstanding the prevalent wind
speeds and loads.

Wind speed statistics
Contact the national meteorological office for the country concerned to identify the likely wind speeds
prevalent at the proposed location. Use this data to estimate the total wind loading on the support structures.

Lightning protection zones Installation planning

Grounding and lightning protection

This section describes the grounding and lightning protection requirements of a PMP 450 installation.

Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in this
guide, when followed correctly, give the user the best protection from the harmful effects of EMD. However
100% protection is neither implied nor possible.

The need for power surge protection
Structures, equipment and people must be protected against power surges (typically caused by lightning) by
conducting the surge current to ground via a separate preferential solid path. The actual degree of protection
required depends on local conditions and applicable local regulations. Cambium recommends that PMP 450
installation is contracted to a professional installer.

Standards
Full details of lightning protection methods and requirements can be found in the international standards IEC
61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the
Canadian Electric Code.



Lightning protection zones
The ‗rolling sphere method‘ (Figure 1) is used to determine where it is safe to mount equipment. An imaginary
sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests against the ground and
a strike termination device (such as a finial or ground bar), all the space under the sphere is considered to be in
the zone of protection (Zone B). Similarly, where the sphere rests on two finials, the space under the sphere is
considered to be in the zone of protection.

Figure 1 Rolling sphere method to determine the lightning protection zones

Equipment

Zone B
Zone A
Zone A

50 m

Zone B

Assess locations on masts, towers and buildings to determine if the location is in Zone A or Zone B:
Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in this zone.
Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone
significantly reduces the possibility of a direct strike. Mount equipment in this zone.

Never mount equipment in Zone A. Mounting in Zone A may put equipment, structures and life at risk.


General protection requirements Installation planning

General protection requirements
To adequately protect a PMP 450 installation, both ground bonding and transient voltage surge suppression
are required.

Basic requirements
The following basic protection requirements must be implemented:
The equipment (AP, SM or GPS receiver) must be in ‗Zone B‘ (see Lightning protection zones on page 1-7).
The AP must be grounded to the supporting structure.
A surge suppression unit (600SS) must be installed on the outside of the building
The distance between the SM and 600SS should be kept to a minimum.
The drop cable must not be laid alongside a lightning air terminal.
All grounding cables must be a minimum size of 10 mm2 csa (8AWG), preferably 16 mm2 csa (6AWG), or
25 mm2 csa (4AWG).

Grounding cable requirements
When routing, fastening and connecting grounding cables, the following requirements must be implemented:
Grounding conductors must be run as short, straight, and smoothly as possible, with the fewest possible
number of bends and curves.
Grounding cables must not be installed with drip loops.
All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90° (Figure 2). A
diagonal run is preferable to a bend, even though it does not follow the contour or run parallel to the
supporting structure.
All bends, curves and connections must be routed towards the grounding electrode system, ground rod, or
ground bar.
Grounding conductors must be securely fastened.
Braided grounding conductors must not be used.
Approved bonding techniques must be used for the connection of dissimilar metals.



Figure 2 Grounding cable minimum bend radius and angle

Radius not less
than 203 mm (8 in)
Angle not less
than 90°

Protection requirements for a mast or tower installation
If the AP or SM is to be mounted on a metal tower or mast, then in addition to the general protection
requirements (above), the following requirements must be observed:
The equipment must be lower than the top of the tower or its lightning air terminal.
The metal tower or mast must be correctly grounded.

Schematic examples of mast or tower installations are shown in Figure 3.

requirements (above), the following requirements must be observed:
The equipment must be lower than the top of the building or its lightning air terminal.
The building must be correctly grounded.

Protection requirements on a high rise building Installation planning

Protection requirements on a high rise building
If the AP is to be mounted on a high rise building, it is likely that cable entry is at roof level (Figure 5) and the
equipment room is several floors below. The following additional requirements must be observed:
The AP must be below the lightning terminals and finials.
A grounding conductor must be installed around the roof perimeter, to form the main roof perimeter
lightning protection ring.
Air terminals are typically installed along the length of the main roof perimeter lightning protection ring
typically every 6.1m (20ft).
The main roof perimeter lightning protection ring must contain at least two down conductors connected to
the grounding electrode system. The down conductors should be physically separated from one another, as
far as practical.

Power density exposure limit
Install the radios for the PMP 450 family of PMP wireless solutions so as to provide and maintain the
minimum separation distances from all persons.

The applicable power density exposure limit from the standards (see Human exposure to radio frequency
energy on page 2-9) is:
10 W/m2 for RF energy in the 5.8 GHz frequency bands.

Calculation of power density

The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst case
analysis. Details of the assessment to EN50383:2002 can be provided, if required.

Peak power density in the far field of a radio frequency point source is calculated as follows:

P .G
S
4 d2
Where: Is:
S power density in W/m2

P maximum average transmit power
capability of the radio, in W



G total Tx gain as a factor, converted from dB
d distance from point source, in m

Rearranging terms to solve for distance yields:

P.G
d
4 .S

Calculated distances and power compliance margins
Table 10 shows calculated minimum separation distances, recommended distances and resulting margins for
each frequency band and antenna combination. These are conservative distances that include compliance
margins. At these and greater separation distances, the power density from the RF field is below generally
accepted limits for the general population.

PMP 450 equipment adheres to all applicable EIRP limits for transmit power when operating in MIMO mode.
Separation distances and compliance margins include compensation for both transmitters.

Explanation of terms used in Table 10:
Tx burst – maximum average transmit power in burst (Watt)
P – maximum average transmit power capability of the radio (Watt) (combined transmitters)
G – total transmit gain as a factor, converted from dB
S – power density (W/m2)
d – minimum distance from point source (meters)
R – recommended distances (meters)
C – compliance factor

all frequency bands.



Compliance with radio regulations

This section describes how the PMP 450 complies with the radio regulations that are enforced in various
countries.

Changes or modifications not expressly approved by Cambium could void the user‘s authority to operate the
system.

Type approvals
This system has achieved Type Approval in various countries around the world. This means that the system
has been tested against various local technical regulations and found to comply. The frequency bands in which
the system operates may be ‗unlicensed‘ and, in these bands, the system can be used provided it does not cause
interference. The system is not guaranteed protection against interference from other products and
installations.

Table 9 lists the radio specification type approvals that have been granted for PMP 450 frequency variants.

FCC compliance testing
With GPS synchronization installed, the system has been tested for compliance to US (FCC) specifications. It
has been shown to comply with the limits for emitted spurious radiation for a Class B digital device, pursuant
to Part 15 of the FCC Rules in the USA. These limits have been designed to provide reasonable protection
against harmful interference. However the equipment can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to other radio communications.
There is no guarantee that interference will not occur in a particular installation.

A Class B Digital Device is a device that is marketed for use in a residential environment, notwithstanding
use in commercial, business and industrial environments.


Region Codes Reference information

Notwithstanding that Cambium has designed (and qualified) the PMP 450 products to generally meet the
Class B requirement to minimize the potential for interference, the PMP 450 product range is not marketed
for use in a residential environment.

Region Codes
Table 12 lists the region codes available on PMP 450 AP and SM units. Region code settings affect the radios
in the following ways:

Safety precautions before installation Preparing for installation

Preparing for installation

This section describes the checks to be performed before proceeding with the installation.

Unit pre-configuration
It is common practice to pre-configure the units during staging before site installation by performing
the following tasks from the PMP 450 Configuration and User Guide
Task 1: Connecting to the unit
Task 2: Configuring IP and Ethernet interfaces
Task 3: Upgrading the software version and using CNUT
Task 4: Configuring General and Unit settings
Task 5: Configuring security
Task 6: Configuring radio parameters
Task 7: Setting up SNMP agent
Task 8: Configuring syslog
Task 9: Configuring remote access
Task 10: Monitoring the AP-SM link
Task 11: Configuring quality of service
Task 12: Configuring a RADIUS server

If the units are to be pre-configured during staging, the safety precautions below MUST be observed.

Safety precautions before installation
All national and local safety standards must be followed while developing a site, installing equipment,
or performing maintenance.

Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate as soon
as they are powered up.



Observe the following guidelines:
Never work in front of the antenna when the unit is powered.
Always power down the module when connecting and disconnecting the drop cable from the power
supply.

Protection requirements
The installation must meet the requirements defined in Grounding and lightning protection on page 1-
6.

Preparing personnel
In no event shall Cambium Networks be liable for any injury or damage caused during the installation
of the Cambium PMP 450 equipment.

Ensure that only qualified personnel undertake the installation of a PMP 450 system.

Ensure that all safety precautions are observed.

Preparing inventory
Perform the following inventory checks:
Check that the correct components are available, as described in Ordering components on page 1-
13.
Check the contents of all packages against their packing lists.

Preparing tools
Check that following specific tools are available, in addition to general tools:
RJ45 crimp tool (it must be the correct tool for the type of RJ45 being used).
Personal Computer (PC) with 10 or 100 BaseT Ethernet port
Internet Explorer or Firefox
Ethernet patch cables

For more information, see section Recommended tools for PMP 450 equipment installation on page 4-
2.


Configuring for Test Preparing for installation

Testing the Components

The best practice is to connect all components—APs, SMs, GPS antenna (if applicable), and CMM (if
applicable)—in a test setting and initially configure and verify them before deploying them to an
installation. In this way, any configuration issues are worked out before going on-site, on a tower, in
the weather, where the discovery of configuration issues or marginal hardware is more problematic and
work-flow affecting.

Unpacking Components
When you receive these products, carefully inspect all shipping boxes for signs of damage. If you find
damage, immediately notify the transportation company.

As you unpack the equipment, verify that all the components that you ordered have arrived. Save all
the packing materials to use later as you transport the equipment to and from installation sites.

Configuring for Test
You can use either of two methods to configure an AP:
Use the Quick Start feature of the product. For more information on Quick Start, see Using the
Quick Start Configuration Wizard of the AP on Page 3-20.
Manually set each parameter.

After you change configuration parameters on a GUI web page:
Before you leave a web page, click the Save button to save the change(s).
After making change(s) on multiple web pages, click the Reboot button to reboot the module and
implement the change(s).

Configuring the Computing Device for Test
If your computer is configured for Dynamic Host Configuration Protocol (DHCP), disconnect the
computer from the network. If your computer is instead configured for static IP addressing
Set the static address in the 169.254 network (see section
Set the subnet mask to 255.255.0.0.
For detailed instructions, see section Configuring the management PC on page 3-16.



Default Module Configuration
From the factory, the APs and SMs are all configured to not transmit on any frequency. This
configuration ensures that you do not accidentally turn on an unsynchronized module. Site
synchronization of modules is required because
modules
o cannot transmit and receive signals at the same time.
o use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink
frames.
when one module transmits while an unintended module nearby receives signal, the transmitting
module may interfere with or desense the receiving module. In this context, interference is self-
interference (within the same network).

Standards for Wiring
Modules automatically sense whether the Ethernet cable in a connection is wired as straight-through or
crossover. You may use either straight-through or crossover cable to connect a network interface card
(NIC), hub, router, or switch to these modules. For a straight-through cable, use the EIA/TIA-568B
wire color-code standard on both ends. For a crossover cable, use the EIA/TIA-568B wire color-code
standard on one end, and the EIA/TIA-568A wire color-code standard on the other end.
Where you use the AC wall adapter
the power supply output is +29.5 VDC.
the power input to the SM is +11.5 VDC to +30 VDC.
the maximum Ethernet cable run is 328 feet (100 meters).

Best Practices for Cabling
The following practices are essential to the reliability and longevity of cabled connections:
Use only shielded cables to resist interference.
For vertical runs, provide cable support and strain relief.
Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal expansion and
contraction and to facilitate terminating the cable again when needed.
Include a drip loop to shed water so that most of the water does not reach the connector at the
device.
Properly crimp all connectors.
Use dielectric grease on all connectors to resist corrosion.
Use only shielded connectors to resist interference and corrosion.

Recommended Tools for Wiring Connectors
The following tools may be needed for cabling the AP:
RJ-11 crimping tool
RJ-45 crimping tool
electrician scissors
wire cutters
cable testing device.

Wiring Connectors
The following diagrams correlate pins to wire colors and illustrate crossovers where applicable.

Overriding Forgotten IP Addresses or Passwords on AP and SM
A small adjunctive product allows you to temporarily override some AP/SM settings and thereby
regain control of the module by powering the module on with the plug inserted into the unit‘s
synchronization (RJ11) port. This override plug is needed for access to the module in any of the
following cases:
You have forgotten either
o the IP address assigned to the module.
o the password that provides access to the module.
The module has been locked by the No Remote Access feature.
You want local access to a module that has had the 802.3 link disabled in the Configuration page.

You can configure the module such that, when it senses the override plug, it responds by either
resetting the LAN1 IP address to 169.254.1.1, allowing access through the default configuration
without changing the configuration, whereupon you will be able to view and reset any non-default
values as you wish.
resetting all configurable parameters to their factory default values.



Constructing an Override Plug
You can either purchase or fabricate an override plug as follows. To purchase an override plug for a
nominal fee, order the plug at http://www.best-tronics.com. To fabricate an override plug, perform the
following steps.

1 Install an RJ-11 6-pin connector onto a 6-inch length of CAT 5 cable

2 Pin out all 6-pins.

3 Short (solder together) Pins 4 and 6 on the other end. Do not connect any other wires to
anything.

Pin 1 white / orange Pin 1
Pin 2 white / green Pin 2
Pin 3 white / blue Pin 3
Pin 4 green Pin 6
Pin 5 blue Pin 5
Pin 6 orange Pin 4



Using the Override Plug
The following section details usage of the override plug to regain access to an AP or SM module.

While the override plug is connected to a module, the module can neither register nor allow
registration of another module.

To regain access to the module, perform the following steps.

1 Insert the override plug into the RJ-11 GPS utility port of the module.

2 Power cycle by removing, then re-inserting, the Ethernet cable.
RESULT: The module boots with the default IP address of 169.254.1.1, password fields blank,
and all other configuration values as previously set.

3 Wait approximately 30 seconds for the boot to complete.

4 Remove the override plug.

5 Set passwords and IP address as desired.

6 Change configuration values if desired.

7 Click the Save Changes button.

8 Click the Reboot button.


Configuring the management PC Preparing for installation

Configuring a Point-to-Multipoint Link for Test

It is important to state the AP and SM units first to verify proper registration before deploying the
modules to the site. To begin configuring the modules for test, see the sections below:

Configuring the management PC
To configure the local management PC to communicate with the PMP 450 AP or SM, proceed as
follows:

Procedure 1 Configuring the management PC

1 Select Properties for the Ethernet port.

2 Select the Internet Protocol (TCP/IP) item (in Windows 7, this item is called ―Internet Protocol
Version 4 (TCP/IPv4):

3 Click on Properties.



4 Enter an IP address that is valid for the 169.254.X.X network, avoiding:

169.254.0.0 and 169.254.1.1 and 169.254.1.2

A good example is 169.254.1.3:

5 Enter a subnet mask of 255.255.255.0.

Leave the default gateway blank.


Powering the AP or SM for test configuration Preparing for installation

Powering the AP or SM for test configuration
Perform the following steps to power on the AP or SM.

Table 23 Setting up the AP for Quick Start configuration

1 Plug one end of a CAT 5 Ethernet cable into the AP.

2 Plug the Ethernet cable connector labeled To Radio into the jack in the pig tail that hangs
from the power supply.

3 Plug the other connector of the pig tail (this connector labeled To Computer) into the Ethernet
jack of the computing device.

4 Plug the power supply into an electrical outlet.

From this point until you remove power from the AP, stay at least as far from the AP as the
minimum separation distance specified in Minimum separation distances on page v.

The AP interface provides a series of web pages to configure and monitor the unit. You can access the
web-based interface through a computing device that is either directly connected or connected through
a network to the AP. If the computing device is not connected to a network when you are configuring
the module in your test environment, and if the computer has used a proxy server address and port to
configure a module, then you may need to first disable the proxy setting in the computer.

Perform the following procedure to toggle the computer to not use the proxy setting.

Procedure 2 Bypassing browser proxy settings to access module web pages

1 Launch Microsoft Internet Explorer

2 Select Tools, Internet Options, Connections, LAN Settings. Alternate web browser menu
selections may differ.

3 Uncheck the Use a proxy server... box.

In the address bar of your browser, enter the IP address of the AP. (For example, enter
http://169.254.1.1 to access the AP through its default IP address). The AP responds by
opening the General Status tab of its Home page.



Logging into the web interface
To log into the web interface as a system administrator, proceed as follows:

Procedure 3 Logging into the web interface

1 Start the web browser from the management PC.

2 Type the IP address of the unit into the address bar. The factory default IP address is
169.254.1.1. Press ENTER. The web interface General Status page is displayed:

Figure 12 AP General Status page

3 Log in with the administrator username and password (by default, the administrator username is
―admin‖ and the administrator password is blank)


Using the Quick Start Configuration Wizard of the Preparing for installation
AP

Using the Quick Start Configuration Wizard of the AP
To proceed with the test setup, after logging into the web management interface click the Quick Start

13 Wait until the indicator LEDs are not red.

14 Trigger your browser to refresh the page until the AP redisplays the General Status tab.

15 Wait until the red indicator LEDs are not lit.



Configuring time settings of the AP
To proceed with the test setup, click the Configuration link on the left side of the General Status tab.
When the AP responds by opening the Configuration page to the General tab, click the Time tab.

Figure 19 Time tab of the AP

To have each log in the AP correlated to a meaningful time and date, either a reliable network element
must pass time and date to the AP or you must set the time and date whenever a power cycle of the AP
has occurred. A network element passes time and date in any of the following scenarios:
A connected CMM passes time and date (GPS time and date, if received).
A connected CMMmicro passes the time and date (GPS time and date, if received), but only if both
the CMMmicro is operating on CMMmicro Release 2.1 or later release. (These releases include an
NTP server functionality.)
A separate NTP server is addressable from the AP.

If the AP should obtain time and date from a CMMmicro, CMM4, or a separate NTP server, enter the
IP address of the CMM or NTP server on this tab. To force the AP to obtain time and date before the
first (or next) 15-minute interval query of the NTP server, click Get Time through NTP.


Configuring time settings of the AP Preparing for installation

If you enter a time and date, the format for entry is

Figure 20 Time and date entry formats

Time : hh / mm / ss

Date : MM / dd / yyyy

where
hh represents the two-digit hour in the range 00 to 24
mm represents the two-digit minute
ss represents the two-digit second
MM represents the two-digit month
dd represents the two-digit day
yyyy represents the four-digit year

Proceed with the time setup as follows.

Procedure 5 Entering AP time setup information

1 Enter the appropriate information in the format shown above.

2 Then click the Set Time and Date button.

The time displayed at the top of this page is static unless your browser is set to
automatically refresh

Powering the SM for test
Procedure 6 Powering the SM for test

1 In one hand, securely hold the top (larger shell) of the SM. With the other hand, depress the
lever in the back of the base cover (smaller shell). Remove the base cover.

2 Plug one end of a CAT 5 Ethernet cable into the SM RJ-45 jack.

3 Plug the other end of the Ethernet cable into the jack in the pig tail that hangs from the power
supply.

4 Roughly aim the SM toward the AP.



5 Plug the power supply into an electrical outlet.

From this point until you remove power from the AP, stay at least as far from the AP as the
minimum separation distance specified in Calculated distances and power compliance margins.

6 Repeat the foregoing steps for each SM that you wish to include in the test.

Viewing the Session Status tab of the AP to determine test
registration
Once the SMs under test are powered on, return to the computing device to determine if the SM units
have registered to the AP.

Procedure 7 Viewing the AP Session Status tab

1 On the AP web management GUI, navigate to Home, Session Status:

Figure 21 Session Status tab of AP

2 Verify that for each SM MAC address (printed on the SM housing) the AP has established a
registered session by verifying the ―State‖ status of each entry.

If no SMs are registered to this AP, then the Session Status tab displays the simple message No
sessions. In this case, try the following steps.


Viewing the Session Status tab of the AP to Preparing for installation
determine test registration

1 More finely aim the SM or SMs toward the AP.

2 Recheck the Session Status tab of the AP for the presence of LUIDs.

3 If still no LUIDs are reported on the Session Status tab, click the Configuration button on the
left side of the Home page.
RESULT: The AP responds by opening the AP Configuration page.

4 Click the Radio tab.

5 Find the Color Code parameter and note the setting.

6 In the same sequence as you did for the AP directly under Configuring a Point-to-Multipoint
Link for Test on Page 3-16, connect the SM to a computing device and to power.

7 On the left side of the SM Home page, click the Configuration button.
RESULT: The Configuration page of the SM opens.


9 If the transmit frequency of the AP is not selected in the Custom Radio Frequency Scan
Selection List parameter, select the frequency that matches.

10 If the Color Code parameter on this page is not identical to the Color Code parameter you noted
from the AP, change one of them so that they match.

11 At the bottom of the Radio tab for the SM, click the Save Changes button.


13 Allow several minutes for the SM to reboot and register to the AP.

14 Return to the computing device that is connected to the AP.

15 Recheck the Session Status tab of the AP for the presence of LUIDs.

The Session Status tab provides information about each SM that has registered to the AP. This
information is useful for managing and troubleshooting a system. All information that you have
entered in the Site Name field of the SM displays in the Session Status tab of the linked AP.

The Session Status tab also includes the current active values on each SM (LUID) for MIR, and
VLAN, as well as the source of these values (representing the SM itself, Authentication Server, or the
AP and cap, if any—for example, APCAP as shown above).. As an SM registers to the AP,
the configuration source that this page displays for the associated LUID may change. After
registration, however, the displayed source is stable and can be trusted.

Idle subscribers may be included or removed from the session status display by enabling or disabling,
respectively, the Show Idle Sessions parameter. Enabling or disabling this parameter only affects the
GUI display of subscribers, not the registration status.



The Session Status tab of the AP provides the following parameters.

Table 24 AP Session Status Attributes

Attribute Meaning
LUID This field displays the LUID (logical unit ID) of the SM. As each SM
registers to the AP, the system assigns an LUID of 2 or a higher unique
number to the SM. If an SM loses registration with the AP and then
regains registration, the SM will retain the same LUID.

The LUID associated is lost when a power cycle of the AP occurs.

Both the LUID and the MAC are hot links to open the interface to the SM.
In some instances, depending on network activity and network design, this
route to the interface yields a blank web page. If this occurs, refresh your
browser view.

MAC This field displays the MAC address (or electronic serial number) of the
SM. Both the LUID and the MAC are hot links to open the interface to the
SM. In some instances, depending on network activity and network design,
this route to the interface yields a blank web page. If this occurs, refresh

Attribute Meaning

AirDelay This field displays the distance of the SM from the AP. To derive the
distance in meters, multiply the displayed number by 0.3048. At close
distances, the value in this field is unreliable.

Session Count This field displays how many sessions the SM has had with the AP.
Typically, this is the sum of Reg Count and Re-Reg Count. However, the
result of internal calculation may display here as a value that slightly
differs from the sum.

If the number of sessions is significantly greater than the number for other
SMs, then this may indicate a link problem (check mounting, alignment,
receive power levels) or an interference problem (conduct a spectrum scan).

Reg Count When an SM makes a registration request, the AP checks its local data to
see whether it considers the SM to be already registered. If the AP
concludes that the SM is not, then the request increments the value of this
field.


Re-Reg Count When an SM makes a registration request, the AP checks its local data to
see whether it considers the SM to be already registered. If the AP
concludes that the SM is not, then the request increments the value of this
field. Typically, a Re-Reg is the case where both
an SM attempts to reregister for having lost communication with the
AP.
the AP has not yet observed the link to the SM as being down.

◦ Canada
◦ India
◦ Ireland
◦ United States
◦ Other

The SM radio automatically inherits the Region Code type of the AP.
This behavior ignores the value of the Region Code parameter in the SM,
even when the value is None. Nevertheless, since future system software
releases may read the value in order to configure some other region-
sensitive feature(s), you should always set the value that corresponds to
the local region.
Unlike selections in other parameters, your Region Code selection
requires a Save Changes and a Reboot cycle before it will force the
context-sensitive GUI to display related options (for example, after the
Region Code is set, and a second after related options are set.

NOTE: This indication confirms that the AP is properly functional.

2 While your browser is directed to this General Status tab, note (or print) the values of the
following fields:
Device type
Software Version
Software BOOT Version
Board Type
FPGA Version

3 Systematically ensure that you can retrieve this data (from a database, for example) when you
later prepare to deploy the AP.


Concluding the Test of Point-to-Multipoint Links Preparing for installation

Preparing Components for Deployment

Your test of the modules not only verified that they are functional, but also yielded data that you have
stored about them. Most efficiently preparing modules for deployment involves
retrieving that data.
systematically collecting the data into a single repository, while keeping a strong (quick)
association between the data and the module.
immediately merging module access data into this previously stored data.

Correlating Component-specific Information
You can use the data that you noted or printed from the Status pages of the modules to
store modules for future deployment.
know, at a glance, how well-stocked you are for upcoming network expansions.
efficiently draw modules from stock for deployment.
plan any software updates that you
o wish to perform to acquire features.
o need to perform to have the feature set be consistent among all modules in a network
expansion.

You can make these tasks even easier by collecting this data into a sort-able database.

Ensuring Continuing Access to the Modules
As you proceed through the steps of configuration, you will set values for parameters that specify the
sync source, data handling characteristics, security measures, management authorities, and other
variables for the modules. While setting these, you will also tighten access to the module, specifically in
the Color Code parameter of Configuration page
the Display-Only Access and Full Access password parameters of the Configuration page.
the addressing parameters of the IP Configuration page.

Before you set these, consider whether and how you may want to set these by a self-devised scheme. A
password scheme can help you when you have forgotten or misfiled a password. An IP addressing
scheme may be essential to the operation of your network and to future expansions of your network.



As you set these, note the color code and note or print the parameters you set on the Configuration
page tabs. Immediately associate them with the following previously stored data about the modules:
device type, frequency band, and MAC address
software version and encryption type
software boot version
FPGA version

Utilizing the Installation Color Code feature
With this feature enabled on the AP and SM, operators may install and remotely configure SMs
without having to configure matching color codes between the modules. While the SM is accessible for
configuration from above the AP (for remote provisioning) and below the SM (for local site
provisioning), no user data is passed over the radio link. SMs with Installation Color Code enabled will
first try any configured Color Code values first, then will use the Installation Color Code feature as a
last result to connect to the AP. The status of the Installation Color Code can be viewed on the AP
Eval web GUI page, and when the SM is registered using the Installation Color Code the message ―SM
is registered via ICC – Bridging Disabled!‖ is displayed in red on every SM GUI page. The Installation
Color Code parameter is configurable without a radio reboot for both the AP and SM. If an SM is
registered via Installation Color Code and the feature is then disabled, operators will need to reboot the
SM or force it to reregister (i.e. using the Rescan APs functionality on the AP Eval page).

PMP 450 Installation Guide Installing an SM

Installing an SM
Installing a PMP 450 Series SM consists of two procedures:
Physically installing the SM on a residence or other location and performing a course alignment
using the alignment tool.
Verifying the AP to SM link and finalizing alignment using review of power level, link tests, and
review of registration and session counts.

Procedure 16 Installing the PMP 450 SM

1 Choose the best mounting location for the SM based on section Installation planning.

2 Use stainless steel hose clamps or equivalent fasteners to lock the SM into position.

3 Remove the base cover of the SM.

4 Terminate the UV outside grade Category 5 Ethernet cable with an RJ-45 connector, and
connect the cable to the SM.

5 Wrap a drip loop in the cable.

6 Optionally, attach the SM to the arm of the Passive Reflector dish assembly or snap a LENS
onto the SM.

7 Wrap an AWG 10 (or 6mm2) copper wire around the Ground post of the SM

8 Tighten the Ground post locking nut in the 600SS onto the copper wire.

PMP 450 Installation Guide Installing an SM reflector dish

Installing an SM reflector dish
The internal patch antenna of the module illuminates the Passive Reflector Dish from an offset
position. The module support tube provides the proper angle for this offset.

Figure 45 Reflector dish assembly, exploded view

Installing reflector dish when both modules mounted at same
elevation
For cases where the other module in the link is mounted at the same elevation, fasten the mounting
hardware leg of the support tube vertical for each module. When the hardware leg is in this position
the reflector dish has an obvious downward tilt.
the module leg of the support tube is not vertical.

For a mount to a non-vertical structure such as a tapered tower, use a plumb line to ensure that the
hardware leg is vertical when fastened. Proper dish, tube, and module positions for a link in this case
are illustrated in Figure 46. The dish is tipped forward, not vertical, but the focus of the signal is
horizontal.


Installing an SM reflector dish Installing Components

Figure 46 Correct SM angle mounting with reflector dish

--------------------------------EARTH--------------------------

Improper dish, tube, and module positions for this case are illustrated in Figure 47.

Figure 47 Incorrect SM angle mounting with reflector dish

--------------------------------EARTH--------------------------

Installing reflector dish when modules mounted at different
elevations
For cases where the other module in the link is mounted at a different elevation, the assembly
hardware allows tilt adjustment. The proper angle of tilt can be calculated as a factor of both the
difference in elevation and the distance that the link spans. Even in this case, a plumb line and a
protractor can be helpful to ensure the proper tilt. This tilt is typically minimal.

The number of degrees to offset (from vertical) the mounting hardware leg of the support tube is equal
to the angle of elevation from the lower module to the higher module (b in the example provided in
section ―Calculating the Aim Angles‖ of the PMP 450 Planning Guide).



Configuring an AP-SM Link
To initially configure the AP-SM over-the-air link after the SM has been installed, perform the
following steps.

Procedure 17 Configuring the AP-SM link

1 Using a computer (laptop, desktop, portable device) connected to the SM, open a browser and
access the SM using the default IP address of http://169.254.1.1 (or the IP address configured in
the SM, if one has been configured.)

2 In the left-side menu, select Configuration.

3 Click the General tab.

4 In the left-side menu, select Tools.

5 Click the AP Evaluation tab.

6 Among the listed APs (each shown with a unique Index number), find the AP whose Power
Level value is highest (or find the ESN of the AP to which you were instructed to establish a
link).

7 Write down the Frequency and Color Code values of the AP in the link.

8 In the left-side menu of the SM interface, select Configuration.


10 At the Custom Radio Frequency Scan Selection List parameter, uncheck all frequencies except
the one on which the AP in the link is broadcasting.

11 At the Color Code parameter, enter the code number that was shown for that AP in the AP
Evaluation tab.



14 Fine-adjust the SM mounting, if needed, to improve Power Level according to your company
standards.

15 Retighten the hardware that secures the mounting.

16 In the left-side menu, select Tools.


Installing an SM reflector dish Installing Components

17 Click the Link Capacity Test tab..
Perform several link tests of 10-second duration as follows:
Type into the Duration field how long (in seconds) the RF link should be tested.
Leave the Packet Length field (when present) set to the default of 1522 bytes or type into
that field the packet length at which you want the test conducted.
Leave the Number of Packets field set to 0 (to flood the link).
Click the Start Test button.
View the results of the test.


19 If an element management system such as Wireless Manager will be used to manage the SM via
SNMP, perform the following steps:
Click the SNMP tab.
At the Read Permissions parameter, select Read/Write.
Under Site Information, type complete data into the three parameters: Site Name, Site
Contact, Site Location.
Click the Save Changes button.


Monitoring an AP-SM Link
After the SM installer has configured the link, either an operator in the network office or the SM
installer in the field (if read access to the AP is available to the installer) should perform the following
procedure. Who is authorized and able to do this may depend on local operator password policy,
management VLAN setup, and operational practices.

Procedure 18 Monitoring the AP-SM link for performance

1 Access the interface of the AP.

2 In the left-side menu of the AP interface, select Home.



3 Click the Session Status tab.

Figure 48 AP Session Status tab

4 Find the Session Count line under the MAC address of the SM.

5 Check and note the values for Session Count, Reg Count, and Re-Reg Count.

6 Briefly monitor these values, occasionally refreshing this page by clicking another tab and then
the Session Status tab again.

7 If these values are low (for example, 1, 1, and 0, respectively, meaning that the SM registered
and started a stable session once) and are not changing
consider the installation successful.
monitor these values from the network office over the next several hours and days.
If these values are greater than 1, 1, and 0, or they increase while you are monitoring them,
troubleshoot the link.

received signal. An acceptable link displays an RSSI value of greater than 700.

RxBabErr Field This field displays how many receiver babble errors occurred.

RxOverrun Field This field displays how many receiver overrun errors occurred on the Ethernet
controller.

Secure Shell A trademark of SSH Communications Security.

Self-interference Interference with a module from another module in the same network.

SES/2 Third-from-right LED in the module. In the Access Point Module and
Backhaul timing master, this LED is unused. In the operating mode for a
Subscriber Module or a Backhaul timing slave, this LED flashes on and off to
indicate that the module is not registered. In the aiming mode for a Subscriber
Module or a Backhaul timing slave, this LED is part of a bar graph that
indicates the quality of the RF link.

SFTP Secure File Transfer Protocol.

Simple Network Standard that is used for communications between a program (agent) in the
Management network and a network management station (monitor). Defined in RFC 1157.
Protocol See http://www.faqs.org/rfcs/rfc1157.html.

Term Definition
SM Customer premises equipment (CPE) device that extends network or Internet
services by communication with an Access Point Module or an Access Point
cluster.

SM MIB Management Information Base file that defines objects that are specific to the
Subscriber Module or Backhaul timing slave. See also Management Information
Base.

SNMP See Simple Network Management Protocol, defined in RFC 1157.

SNMP Trap Capture of information that informs the network monitor through Simple
Network Management Protocol of a monitored occurrence in the module.

Standard See Fade Margin.
Operating Margin

Static IP Address Assignment of Internet Protocol address that can be changed only manually.
Assignment Thus static IP address assignment requires more configuration time and
consumes more of the available IP addresses than DHCP address assignment
does. RFC 2050 provides guidelines for the static allocation of IP addresses. See
http://www.faqs.org/rfcs/rfc2050.html. See also DHCP.

su - A command that opens a Linux® operating system session for the user root.

Subnet Mask 32-bit binary number that filters an IP address to reveal what part identifies
the network and what part identifies the host. The number of subnet mask bits
that are set to 1 indicates how many leading bits of the IP address identify the
network. The number of subnet mask bits that are set 0 indicate how many
trailing bits of the IP address identify the host.

Subscriber Module Customer premises equipment (CPE) device that extends network or Internet
services by communication with an Access Point Module or an Access Point
cluster.

Sustained Data Preset rate limit of data transfer.
Rate

Switch Network element that uses the port that is associated with the physical address
of another to pass data to only the intended recipient. Compare to Bridge and
Router.

SYN/1 Second-from-right LED in the module. In the Access Point Module or in a
registered Subscriber, this LED is continuously lit to indicate the presence of
sync. In the operating mode for a Subscriber Module, this LED flashes on and
to indicate that the module is not registered.

Sync GPS (Global Positioning System) absolute time, which is passed from one
module to another. Sync enables timing that prevents modules from
transmitting or receiving interference. Sync also provides correlative time
stamps for troubleshooting efforts.

Term Definition
TCP Alternatively known as Transmission Control Protocol or Transport Control
Protocol. The Transport Layer in the TCP/IP protocol stack. This protocol is
applied to assure that data packets arrive at the target network element and to
control the flow of data through the Internet. Defined in RFC 793. See

TDD Time Division Duplexing. Synchronized data transmission with some time slots
allocated to devices transmitting on the uplink and some to the device
transmitting on the downlink.

telnet Utility that allows a client computer to update a server. A firewall can prevent
the use of the telnet utility to breach the security of the server. See
http://www.faqs.org/rfcs/rfc818.html, http://www.faqs.org/rfcs/rfc854.html and

Textual Management Information Base file that defines system-specific textual
Conventions MIB conventions. See also Management Information Base.

Tokens Theoretical amounts of data. See also Buckets.

TOS 8-bit field in that prioritizes data in a IP transmission. See

TxUnderrun Field This field displays how many transmission-underrun errors occurred on the
Ethernet controller.

UDP User Datagram Protocol. A set of Network, Transport, and Session Layer
protocols that RFC 768 defines. These protocols include checksum and address
information but does not retransmit data or process any errors. See

udp User-defined type of port.

U-NII Unlicensed National Information Infrastructure radio frequency band, in the
5.1-GHz through 5.8-GHz ranges.

VID VLAN identifier. See also VLAN.

VLAN Virtual local area network. An association of devices through software that
contains broadcast traffic, as routers would, but in the switch-level protocol.

VPN Virtual private network for communication over a public network. One typical
use is to connect remote employees, who are at home or in a different city, to
their corporate network over the Internet. Any of several VPN implementation
schemes is possible. SMs support L2TP over IPSec (Level 2 Tunneling Protocol
over IP Security) VPNs and PPTP (Point to Point Tunneling Protocol) VPNs,
regardless of whether the Network Address Translation (NAT) feature enabled.
