Replacing or Removing a Module

It is highly recommended that the HP Extended Services zl Module shutdown

before replacing or removing it. You can shut down the module with the

following HP zl switch CLI command:

hostzlswitch# services <slot-id> shutdown

For example:

hostzlswitch# services c shutdown

Shutting down the HP Extended Services zl Module ensures that its Windows

Server 2008 R2 OS is shut down properly and does not experience a power

failure when the module is removed.

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

replace one module with another while the HP zl switch is still powered on,

without interrupting the operation of the rest of the switch ports. If the

modules are not the same type, the switch will need to be rebooted and may

need to be reconfigured.

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 1-11 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.
