Switch Data 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:

cable. In this example, the switches are stacked in a vertical rack or on a table. This configuration
provides redundant connections.

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 connected to the XPS 2200, review this recommended sequence of
events:
If you are using the XPS 2200, install the XPS first at the bottom of the stack. If needed, allow
–
one RU space between the XPS and the first switch above to provide room for cabling.
Connect the 12-pin XPS cables to the XPS 2200.
–
Rack-mount the switches. If you have the optional 1100-W power-supply module, first mount
–
the switch before installing the power-supply module.
Connect the XPS cable to the first switch above the XPS 2200. Connect the stack cables to the
–
first switch above the XPS.
Connect the XPS cable to the second switch above the XPS 2200. Connect the stack cables to
–
the next switch above the XPS.
Repeat until all switches are connected.
–
For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see
the "Planning a StackPower Stack (Catalyst 3750-X Switches)" section on page
is an example of a recommended configuration that uses the supplied 0.5-meter StackWise
1-19. The
provides examples of recommended configurations.
