The Cisco Catalyst 4900M is a 320-Gbps, 250-million-packets-per-second (mpps), two-rack-unit (2RU) fixed-configuration switch with eight fixed wire-speed X2 ports on the base unit and two 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.
As part of the Data Center switching portfolio, the 4900M provides:
- High performance
- Low latency
- 10/100/1000 Ethernet
- 10 Gigabit Ethernet
- A top-of-rack access layer switching solution for rack-optimized servers
As part of the branch switching portfolio, the 4900M provides wire-speed services required for a collapsed LAN, core-distribution deployment. With the unique semi-fixed architecture, the 4900M provides the flexibility to deploy Gigabit Ethernet now, and cost-effectively migrate to10 Gigabit Ethernet as requirements change.
The Catalyst 4900M offers eight fixed wire-speed 10 Gigabit Ethernet ports, and two half-slots which you can fill with any combination of the following:
- 20-port wire-speed 10/100/1000 (RJ-45) half-card
- 8-port (2:1) 10 Gigabit Ethernet (X2) half-card (Cisco TwinGig Converter Module compatible)
- 4-port wire-speed 10 Gigabit Ethernet (X2) half-card
