the catalyst 2960 switch can be deployed as a backbone switch, aggregating 10base-t, 100base-tx, and 1000base-t ethernet traffic from other network devices.

    see the switch software configuration guide for examples showing how you might deploy the switch in your network.

    these are the switch features:

    一、hardware

    1、catalyst 2960-24tc switch?4 10/100base-t ethernet ports and 2 dual-purpose uplinks (two 10/100/1000base-t copper ports and two sfp (small form-factor pluggable) module slots)

    2、catalyst 2960-48tc switch—48 10/100base-t ethernet ports and 2 dual-purpose uplinks (two 10/100/1000base-t copper ports and two sfp module slots)

    3、catalyst 2960-24tt switch—24 10/100base-t ethernet ports and 2 10/100/1000base-t copper uplinks

    4、catalyst 2960-48tt switch—48 10/100base-t ethernet ports and 2 10/100/1000base-t copper uplinks

    5、catalyst 2960g-24tc switch—24 10/100/1000 ethernet ports and 4 of these are dual-purpose uplinks (four 10/1001000base-t copper ports and four sfp module slots)

    二、the switches support these sfp modules:

    1、1000base-sx

    2、1000base-lx/lh

    3、1000base-zx

    4、1000base-bx

    5、1000base-cwdm

    6、100base-fx

    7、100base-bx

    8、100base-lx

    see the release notes for a complete list of supported sfp modules.

    when installed in catalyst 2960 switches, 1000base-t sfp modules can operate at 10, 100, or 1000 mbps in full-duplex mode or at 10 or 100 mbps in half-duplex mode.

    三、configuration?0/100 and 10/100/1000 ports autonegotiate speed and support full-duplex mode or half-duplex mode.

    四、power redundancy桟onnection for an optional cisco rps 675 or cisco rps 300 redundant power system that operates on ac input and supplies backup dc power output to the switch.
