The Catalyst 5000 platform is a 5-slot chassis that supports both wiring closet and data center applications. The Catalyst 5000 supports all supervisor engines and will support all new line cards to create a complete networking solution. The Catalyst 5000 chassis fits into a standard 19 in. (48.26 cm) rack, and all system components are accessible from the same side of the chassis.Supervisor II engine ports on 10/100 ports on Fast EtherChannel-capable line cards enable high-speed connectivity between switches, switches and routers, and switches and servers. Up to four Fast Ethernet ports can be grouped to provide up to 800 Mbps of load-sharing, redundant, and point-to-point connections between the Catalyst 5500, 5509, 5505, 5002, and 5000 switches. To achieve higher bandwidth, Gigabit EtherChannel can be deployed, which supports up to 8 Gbps (full-duplex) of inter-switch bandwidth, and is supported across the Catalyst 5000 Family.This chassis comes with AC power supply, Supervisor II engine and three Fast EtherChannel Switching (100BaseFX,MMF,SC,12 port) WS-X5201 modules.
