How do I replace a stack member on my managed switch?

Make sure the redundant stack connection is in place and functional. All stack members should be connected in a logical ring.
Power down the switch to be removed and disconnect its stack cables.
Remove the switch from the rack.
If the code version of the replacement switch is not the same as the existing stack, update the code. For more information see the How do I upgrade the firmware on my managed switch?.
On the replacement switch, enable stack mode on the ports to connect to your stack cables.
On the stack, if you will be installing a different model switch, remove the unit from the configuration by issuing the command no member <unit-id>.
Install the new switch in the rack:
- If you are installing the same model switch, put it in the same position in the stack as the one that you just removed.
- If you are installing a different model switch you can either put it in the same position as the previous switch, or at the bottom of the stack.
Cable the new switch, following the established order of stacking cables.
Power up the new switch. Verify, by monitoring the master switch console port, that the new switch successfully joins the stack by issuing the show switch command. The new switch should join as a member (never as master; the existing master of the stack should not change).
