Switch Stacking and Power Stacking Guidelines

For general concepts and management procedures for switch stacks, see the switch software
configuration guide on Cisco.com.
Before connecting the switches in a stack, keep in mind these stacking guidelines:

Size of the switch and any optional power-supply module. The 1100-W power-supply module is
longer than the other modules. Stacking switches with the same power-supply modules together
makes it easier to cable the switches. For switch dimensions, see
Specifications."
Length of cable. Depending on the configurations that you have, you might need different-sized
cables. If you do not specify the length of the StackWise cable, the 0.5-meter cable is supplied. If
you need the 1-meter cable or the 3-meter cable, you can order it from your Cisco supplier. For cable
part numbers, see the "StackWise Ports" section on page
Configurations" section on page 2-5
For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see
the "Planning a StackPower Stack" section on page
You can create data stacks with up to four switches in a stack.
