Switches

Catalyst 1900 switches provide up to 24 10-Mbps switched Ethernet connections to 10BaseT-compatible devices (such as single workstations and 10BaseT hubs) and one 10-Mbps connection to an AUI. The switches also provide two 100BaseT connections to servers and backbones.

The Catalyst 2820 series Ethernet switches provide 25 10-Mbps switched Ethernet connections: 24 10-Mbps connections to 10BaseT-compatible devices (such as single workstations and 10BaseT hubs) and one 10-Mbps connection to an AUI. Switches with the optional Catalyst 2820 modules installed can provide 100BaseT, FDDI, and ATM connectivity to servers and backbones.

A Cisco Catalyst 5500 switch.The Catalyst 5500 switch provides high-density switched Ethernet and Fast Ethernet, Token Ring, and Asynchronous Transfer Mode (ATM) switching for both wiring closet and data-center applications, using unshielded twisted-pair (UTP) multimode and single-mode fiber-optic cable. The Catalyst 5500 switch supports switched 10-Mbps Ethernet, Ethernet repeater connections, and switched 100-Mbps Fast Ethernet with backbone connections to Fast Ethernet, ATM, Fiber Distributed Data Interface (FDDI), and Copper Distributed Data Interface (CDDI). Typically, Catalyst 5500 Ethernet interfaces connect workstations and repeaters while the Fast Ethernet interfaces connect to workstations, servers, switches,
