3COM 3C96120M-TPP CB5000 20-PORT EXPANSION MODULE

The CoreBuilder 5000 SwitchModule series supports high-performance, high-density switched Ethernet, switched Fast Ethernet, switched FDDI, and ATM connectivity. A dedicated multi-protocol Integrated Switch Controller (ISC) 4000 ASIC on each SwitchModule provides scalable performance for full wire-speed forwarding on all ports. The modules communicate over the CoreBuilder 5000 2-Gbps PacketChannel backplane, which is optimized for multitechnology environments, and supports intermodule communication of FDDI, Fast Ethernet, or Ethernet and ATM migration. Each CoreBuilder 5000 SwitchModule features a dedicated switching engine ensuring that the other modules will continue to operate even if one module is disabled. In addition, the SwitchModules take full advantage of the fault-tolerant features built into the CoreBuilder 5000 switch.
