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. The 10GBASE-T line card
complies with the IEEE 802.3an standard and supports Gigabit Ethernet and 10 Gigabit Ethernet modes
for up to 330 feet (or 100 meters) on Cat6a and 7 structured cabling and up to 181.5 feet (or 55 meters)
on Cat6 structured cabling.
