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

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

    figure 2-1 through figure 2-5 show the catalyst 3750 switches.

    these are the switch features:

    1?hardware

    (1)?catalyst 3750-24ts?4 10/100 ethernet ports and 2 small form-factor pluggable (sfp) module slots

    (2)?catalyst 3750g-24t?4 10/100/1000 ethernet ports

    (3)?catalyst 3750g-24ts?4 10/100/1000 ethernet ports and 4 sfp module slots

    (4)?catalyst 3750-48ts?8 10/100 ethernet ports and 4 sfp module slots

    (5)?catalyst 3750g-12s?2 sfp module slots

    2?the switches support these sfp modules:

    (1)?1000base-sx

    (2)?1000base-lx

    (3)?1000base-t

    when installed in catalyst 3750 switches, 1000base-t small form-factor pluggable (sfp) modules can either operate at 10, 100, or 1000 mbps in full-duplex mode or in half-duplex mode at 10 or 100 mbps.

    3?configuration

    (1)?for 10/100 ports, autonegotiates the speed and duplex settings

    (2)?for 10/100/1000 ports, autonegotiates the speed and supports only full-duplex mode

    4?the catalyst 3750 switches support stacking. you can stack up to nine switches in a stack by cabling the stackwise ports. stackwise ports are not user-configurable.

    5?switches are hot-swappable

    6?power redundancy

    (1)?connection for optional cisco rps 300 redundant power system that operates on ac input and supplies backup dc power output to the catalyst 3750-24ts, 3750g-24t, 3750-48ts, and 3750g-12s switches.

    the cisco rps 300 does not support the catalyst 3750g-24ts switch.

    (2) connection for optional cisco rps 675 redundant power system that operates on ac input and supplies backup dc power output to the family of catalyst 3750 switches.
