Replacing or Removing a Module

Follow these procedures to replace one module with another, or to remove a

module without replacing it:

1. Remove any network cables from the ports on the module.

2. If the module you want to remove has a shutdown button, make sure to

shut down the module before removing it either by using the CLI

shutdown command or by using the shutdown button.

3. On the module you want to remove from the switch, unscrew the

retaining screws enough to disconnect them from the threaded holes in

the switch.

4. Using the extractor handles pull the module out from the slot.

5. Do one of the following:

• If you will be installing another module in the slot, go to “Installing

the Module in an Unused Slot” on page 17 and begin with step 2.

• If you will not install another module in the slot (that is, leave it

empty), then re-install a slot cover plate over the empty slot opening.

Caution For proper cooling and reduction of electromagnetic emissions, ensure a slot

cover is installed on any unused slot.

6. Reset the switch, if you are exchanging one type of module with a

different type of module in the same slot.

If you are replacing a module with another one of the same type in the

same slot, it is not necessary to reset the switch. The current configuration

for ports in that slot will apply to the new module.
