Cisco is pleased to announce the 8-port 10GBASE-T (RJ-45) half-card for the Cisco Catalyst® 4900M Switch (Figures 1 and 2). The new line card expands the exceptional flexibility of the Cisco Catalyst 4900M and provides a transition path from Gigabit Ethernet to 10 Gigabit Ethernet server access by mixing and matching the new Cisco® 10GBASE-T interface modules with existing Gigabit Ethernet copper and 10 Gigabit Ethernet fiber modules on Cisco Catalyst 4900 Series Switches.
