StackWise Ports
The Catalyst 3750-X switch ships with a 0.5-meter StackWise cable (CAB-STACK-50CM) that you can
use to connect the StackWise ports.
Caution
Use only approved cables (CAB-STACK-50CM, CAB-STACK-1M, CAB-STACK-3M,
CAB-STACK-50CM-NH,CAB-STACK-1M-NH, or CAB-STACK-3M-NH), and connect only to similar
Cisco equipment. Equipment might be damaged if connected to 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)
•
CAB-STACK-50CM-NH= (0.5-meter cable, nonhalogen)
•
CAB-STACK-1M-NH= (1-meter cable, nonhalogen)
•
CAB-STACK-3M-NH= (3-meter cable, nonhalogen)
Power Supply Modules
The switch is powered through one or two internal power supply modules.
Supported power supply modules:
The switch has two internal power supply module slots. You can use two AC modules, two DC modules,
a mixed configuration of one AC and one DC power supply module, or one power supply module and a
blank module.
The switch can operate with either one or two active power supply modules or with power supplied by
an XPS 2200. A Catalyst 3750-X switch that is in a StackPower stack can operate with power supplied
by other switches in the stack.
Table 1-1
and
Table 1-2
show the power supply modules that ship with each switch model. All power
supply modules (except the blank modules) have internal fans. All switches ship with a blank power
supply module in the second power supply slot.
