StackWise Ports

141728

The Catalyst 3750 switch ships with a 0.5-meter StackWise cable (72-2632-XX CABASY) that you can use to connect the StackWise ports.

Caution Use only approved cables (CAB-STACK-50CM, CAB-STACK-1M, or CAB-STACK-3M), and connect only to similar Cisco equipment. Equipment might be damaged if connected to other nonapproved Cisco cables or equipment.

You can order these StackWise cables from your Cisco sales representative:

•CAB-STACK-50CM= (0.5-meter cable)

•CAB-STACK-1M= (1-meter cable)

•CAB-STACK-3M= (3-meter cable)

Power Connectors

The switch is powered through the internal power supply. Except on the Catalyst 3750G-12S-SD switch, you can also connect the Cisco RPS 2300 or the Cisco RPS 675 to provide backup power should the switch internal power supply fail.

Note The Catalyst 3750 switch and the redundant power systems should be connected to the same AC power source.
