  • Page 15: About The Tigerswitch 10/100

    WITCH Overview ™ SMC’s TigerSwitch 10/100 is a Fast Ethernet switch with 48 10BASE-T/100BASE-TX ports, plus two slots for optional slide-in 100BASE-FX or 1000BASE-SX modules. There is also an SNMP-based Network Management Module installed in the rear panel. This module supports both in-band and out-of-band access for managing the switch.

  • Page 16: Switch Architecture

    This prevents errors from being propagated throughout the network. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. This TigerSwitch can be used in a standalone configuration, supporting up to 52 ports.

  • Page 17: Management Options

    Network Management Module that allows the switch to be managed in-band via SNMP or RMON (Groups 1, 2, 3 and 9) protocols, with a Web browser, or remotely via Telnet. The switch also provides a serial port on the rear panel for out-of-band management.
