Planning a Switch Stack
Planning a Switch Stack
If you plan to stack your switches, read these sections:
• Stack Guidelines, page 2-6
• Stack Cabling, page 2-6
• Stack Bandwidth and Partitioning Examples, page 2-8
• Power-On Sequence for Switch Stacks, page 2-9
Stack Guidelines
For general concepts and procedures see the switch software configuration guide on Cisco.com.
Before connecting the switches in a stack, keep in mind these guidelines:
• Connect only Catalyst 2975 switches in a switch stack. The Catalyst 2975 switch does not support
mixed stack configurations. You cannot stack Catalyst 2975 switches with Catalyst 3750 switches
or Catalyst 3750-E switches.
• Depending on your installation, you might need different cables sizes. If you do not specify the
length of the stack cable, the 0.5-meter cable is supplied. If you need the 1-meter or the 3-meter
cable, you can order it from your Cisco supplier. For cable part numbers, see the
“Stack Ports”
section on page 1-8 .
• Access to the switch rear panel and to the rear of the rack. If you do not have access, cable the
switches before rack-mounting.
Stack Cabling
In Figure 2-1 the switches are stacked in a vertical rack or on a table. The connections are redundant.
