WS-C4900M, Cisco Catalyst 4900M 8-port base system.
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.
