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
  • 8-port (2:1) 10GBASE-T half-card
