Switch Stacking and Power Stacking Guidelines

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.

• 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

StackWise Ports, on page 25

. The

Data Stack Cabling Configurations, on page 38

provides examples

of recommended configurations.

• For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see

Planning a StackPower Stack, on page 40

.

• You can create data stacks with up to nine switches in a stack.

Special considerations for the following switch models:

• WS-C3850-24XS-E

• WS-C3850-24XS-S

• WS-C3850-24XU-E

• WS-C3850-24XU-L

• WS-C3850-24XU-S

• WS-C3850-12X48U-L

• WS-C3850-12X48U-S

• WS-C3850-12X48U-E

Information:

• If you set up a stack with these switches, the stack can have a maximum of 8 switches only. Each of the

above switch models have 4 ASIC chips, and the maximum number of ASIC chips per stack cannot
exceed 32.

• If you set up a stack that contains the above switches and other Catalyst 3850 switches, ensure that the

maximum number of ASIC chips is 32.

Note

The Catalyst WS-C3850-48XS switch models do not support power stacking.
