How to Configure the Cisco EtherSwitch Service Module in a Switch Stack
52
Cisco IOS Release 12.2(25)SEC
• Removing powered-up stack members from the stack causes the Cisco EtherSwitch service module
stack to divide (partition) into two or more switch stacks, each with the same configuration. This
can cause an IP address configuration conflict in your network. If you want the switch stacks to
remain separate, change the IP address or addresses of the newly created switch stacks. If you did
not intend to partition the switch stack, follow these steps:
a. Power down the newly created switch stacks.
b. Reconnect them to the original switch stack through their Cisco StackWise ports.
c. Power up the switches.
Note A Cisco EtherSwitch service module does not have an on/off switch. To turn off the Cisco EtherSwitch
service module, issue the service gigabitethernet1/0 shutdown command from the router.
