Replacing or Removing a Module

It is highly recommended that the module be shutdown before replacing or

removing it. To shut down the module, see “Shutting Down XenServer” on

page 2-7.

It is possible to “hot-swap” one module for another of the same type; that is,

replace one module with another while the switch is still powered on, without

interrupting the operation of the rest of the switch ports. If the modules are

not the same type, you must reboot the switch before installing the new

module and the switch may have to be reconfigured.

Caution If you do not reboot the switch before installing the Advanced Services Module

in a slot that used to house a different type of module, the module will fail to

boot.

Caution A 5-second delay is mandatory between removing a module, and either re-

installing it, or replacing it with another.

To replace one module with another, or to remove a module without replacing

it, use the following procedure:

1. Unscrew the retaining screws enough to disconnect them from the

threaded holes in the switch.

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

3. Do one of the following:

• If installing another module of the same type, go to “Installation

Procedure” on page 1-6 and begin with step 2. A switch reset is not

required. The current configuration in that slot will apply to the new

module.

• If another module will not be installed in the slot (that is, the slot will

be left empty), re-install the cover plate over the slot opening.

Caution For proper cooling and reduction of electromagnetic emissions, ensure that

a slot cover is installed on any unused slot. In an operational chassis, an

unused slot should be covered if it is not used for more than 2 minutes.
