B Replacing hardware components

Replacing or removing a controller

HP recommends that the controller be shut down before removing or replacing it. The preferred
method of shutting down the controller is through the CLI:
services <slot-id> shutdown
Where <slot-id> identifies the switch slot containing the controller. A confirmation message
appears. Respond with "y" to continue.
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, the switch must be rebooted.
CAUTION:
and re-installing it or replacing it with another.

and begin with step 2. A switch reset is not required. The current configuration in that
slot will apply to the new controller.
If another controller will not be installed in the slot (the slot will be left empty), re-install
the cover plate over the slot opening using the retaining screws.
CAUTION:
cover is installed on all unused slots.

Replacing the SSD

HP recommends that the controller be shut down before removing or replacing the SSD. The
preferred method of shutting down the controller is through the CLI:

3. Using a Torx T- 1 0, remove the four SSD retaining screws (3 in
4. Slide the SSD towards the faceplate of the controller to disconnect the connectors.
5. Using the pull tab (4 in
6. Install the new SSD into the controller by placing the non-connector side in first, then sliding
the connector side back (away from the faceplate) to engage the connectors.
7. Re-install the four SSD retaining screws using a Torx T- 1 0 screwdriver.
