Removing a Member Switch

Here are the guidelines to removing a member switch from the stack:



You may leave the stack powered on if it is cabled in the duplex-
ring topology, or if it is cabled in the duplex-chain topology and the
switch to be removed is located at the end of the stack.



You should power off the stack if it is wired in the duplex-chain
topology and the member switch to be removed is located between
other switches.

Note

For background information on stack topologies, refer to “Stacking
Port Topologies” on page 55.



If you plan to replace a member switch, the new switch must be the
same model as the switch it is replacing. Otherwise, the operations
of the stack may be unpredictable. For instance, you should not
replace an AT-8100S/16F8-SC Switch with an AT-8100S/24
Switch.



Removing a member switch from an operational stack disrupts IP
connectivity until the stack reforms. However, Layer 2 traffic is not
disrupted.

Here are the steps to removing a member switch from an operational
stack.

1. Power off the member switch.

2. Label and disconnect all of the network cables from the switch.

3. Label and disconnect the stacking cables.

4. To replace the switch with another switch, go to “Adding a New

Member Switch” on page 128. Otherwise, continue with the next step.

5. Connect the stacking cables to the remaining switches.

6. Verify that the stack is operating properly. Refer to “Verifying the

Installation” on page 101.

7. If you want to use the removed member switch as a stand-alone unit,
