Cisco Catalyst 5509 chassis w/ Supervisor Engine III

Cisco Catalyst 5509 chassis w/ Supervisor Engine III ... wiring closet solution, the Catalyst 5509 supports high density, dedicated Token Ring or 10/100/1000 Ethernet switching. The Catalyst 5509 can support high density switching with only a 15 Amp circuit requirement, allowing for easy installation in most wiring closet environments. The Catalyst 5509 also supports all of Cisco's advanced features for the wiring closet, such as automatic protocol broadcast filtering to conserve valuable bandwidth, intelligent multicast forwarding to handle multimedia traffic, and load balancing over redundant links.

The Catalyst 5509 creates an industry-leading Gigabit Ethernet backbone solution to meet the requirements of today's demanding and fast-growing enterprise intranets by supporting up to 38 ports of Gigabit Ethernet and combined with Cisco's Gigabit EtherChannel technology, which enables multiple gigabit Ethernet links to be treated as one logical link, for up to 8 Gbps (full duplex) of device-to-device throughput - the highest port density available today for the Catalyst 5500 series. The Catalyst 5509 chassis fits into a standard 19-inch rack, and all system components are accessible from the same side of the chassis. Only one power supply is required to run a fully configured system.
