The Cisco Catalyst 4000/4500 Series six-port Gigabit Ethernet line card provides six ports of dedicated 1000BASE-X Gigabit Ethernet uplinks for high-speed backbone switch-to-switch applications or small server-farm applications. It uses the versatile GBIC technology so intrabuilding multimode connections can be intermixed with long-distance campus single-mode connections. All ports can utilize Gigabit EtherChannel or IEEE 802.3ad for high-speed interconnection applications.
