Cisco Catalyst 4900M Series
High-Performance Small Form Factor Cisco Catalyst Switch with Flexibility and
Investment Protection for Top of Rack Switching or Midmarket Collapsed
Core/Distribution
Product Overview
The Cisco
®
Catalyst
®
4900M Series (Figure 1) is designed for data center network top of rack
switching and midmarket collapsed core/distirbution. Optimized for ultimate deployment flexibility
for the data center, the Cisco Catalyst 4900M can be deployed for 10/100/1000 server access with
1:1 uplink-to-downlink oversubscription and a mix of 10/100/1000 and 10 Gigabit Ethernet servers
or all 10 Gigabit Ethernet server environments. The Cisco Catalyst 4900M is a 320-Gbps, 250
million packets per second (mpps), two-rack-unit (2RU) fixed-configuration switch with 8 fixed wire-
speed X2 ports on the base unit and 2 optional half-card slots for deployment flexibility and
investment protection. Low latency, scalable buffer memory, and high availability with 1+1 hot
swappable AC or DC power supplies and a field replaceable fan tray optimize the Cisco Catalyst
4900M for any size of data center.
For the midmarket collapsed core/distribution and in branch, the Cisco Catalyst 4900M provides an
ideal solution for space-constrained deployments that require high-performance wire-speed
services and high availability. With the unique semifixed archiecture and support of the TwinGig
converter, the Cisco Catalyst 4900M can be used in a collapsed core distribution LAN deployment
with the flexibility of deploying Gigabit Ethernet now, and cost-effectively migrate to 10 Gigabit
Ethernet as requirements change. The Cisco Catalyst 4900M configuration provides wire-speed
connection, buffers to handle bursty traffic, and a comprehensive set of Layer 3 features required
at the collapsed core/distribution of the network. The Cisco Catalyst 4900M also supports a suite
of ease of management features to simplify operations.
