![Cisco Catalyst 4900M Switch At-a-Glance Overview The Cisco Catalyst® 4900M Switch is a two-rack-unit (2RU) top-of-rack (ToR) data center
access layer switch for use with rack-optimized servers. The Cisco Catalyst 4900M offers exceptional deployment flexibility with an expansive
list of line-card modules to facilitate Gigabit Ethernet to 10 Gigabit Ethernet server access with investment protection and a pay-as-you-grow
model. Customers can mix and match Gigabit Ethernet and 10 Gigabit Ethernet copper and fiber ports in a single 2RU switch (Figure 1). The
Cisco Catalyst 4900M delivers extremely low latency for all packet sizes, deep buffers, and Layer 2 and 3 switching features for flexible
deployments for data center server access, market data architecture, and web services experience providers. The media type flexibility and
Layer 3 feature set make the Cisco Catalyst 4900M an ideal switch for compact core/distribution deployment as well. • •

Gigabit Ethernet (RJ-45) half-car Figure 1. Cisco Catalyst 4900M Offers Significant Mix-and-Match Flexibility The Cisco Catalyst 4900M is
optimized for 10/100/1000 and 10 Gigabit Ethernet access devices. It is unique in the top of rack (ToR) space because it is semi-fixed. This
flexibility provides a cost-effective and modular migration path from Gigabit Ethernet to 10 Gigabit Ethernet (Figure 2). The design of the
Cisco Catalyst 4900M addresses several common challenges data centers face, offering these benefits: • • •
• • Offers hot-swappable flexibility, providing high availability in a dynamic
environment along with investment protection in environments with a constantly changing mix of servers Provides optional half-cards that
can be changed when new servers require different media and port speeds, maintaining the investment in the Cisco Catalyst 4900M base unit
Supports Gigabit Ethernet and 10 Gigabit Ethernet copper (RJ-45) and 10 Gigabit Ethernet fiber (X2) line cards that can be converted to Gigabit
Ethernet fiber (Small Form-Factor Pluggable [SFP]) by using a port adaptor; X2 ports can be converted for use with 10 Gigabit Ethernet SFP+
and CX1 with the OneX adapter (Figure 3) Supports Layer 2 and 3 software images for deployment flexibility Designed with 16 MB of shared
buffers to help prevent performance degradation under heavy traffic loads and help ensure that revenue-producing packets are not lost due
to insufficient buffering Figure 2. Cisco Catalyst 4900M Optimized for 10 Gigabit Ethernet Server (Fiber) Connectivity Figure 3. Cisco Catalyst

Ethernet at Wire Speed Without Oversubscription The switch has 8 fixed wire-speed 10 Gigabit Ethernet ports
typically used to uplink to an aggregation switch. The switch also provides two half-slots that can be filled with any combination of the
