Before you begin
Observe the following precaution when replacing the riser assembly.
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
Your controller enclosure model may vary slightly from what is illustrated
in this document.
Verifying component failure
Use the following method to verify component failure:
Check to see if there is power to the management module or power UID.
If the amber LEDs on the management module or power UID indicate a
failure, the riser assembly may have failed.
NOTE:
An indicated failure of the management module can also be
an indication of failure of the power supply or midplane board.

Removing a riser assembly
1. Power down the controller enclosure with HP P6000 Command
View or the HP P6000 web-based operator control panel (WOCP).
Powering down the controller enclosure also removes power from
the disk enclosures. From HP P6000 Command View:
a. In the navigation pane, select your storage system.
b. Select the Shut down tab.
c. In the Initialized Systems Properties window, the Shutdown
Options window, in the Power the Whole System OFF section,
set a value of up to 60 minutes to delay the power down of
the array (if desired). Click Power OFF.
2. Remove all cables (Fibre Channel and/or SAS, Ethernet, power)
from the enclosure components. Ensure all cabling is marked so as
to facilitate reconnecting later.
3. Pull off the front enclosure bezel, loosen the thumbscrews on each
side that secure the enclosure to the front of the rack, and remove
the enclosure from the rack.
CAUTION:
The controller enclosure is heavy. Two people are
required to remove the enclosure from the rack to
prevent injury.

4. Remove the management module.
a. Lift the latch up on the module (1, Figure 2) and pull the module
out slightly.
b. Position one hand under the module, and with the other hand,
pull the module out of the controller enclosure (2, Figure 2).

5. Remove the top access cover.
a. Loosen the cover thumbscrew (1, Figure 3).
b. Slide the access panel out and off (2, Figure 3).

7. Pull up on the riser assembly to unseat it from its mating connector
on the midplane board (Figure 4).

Installing a riser assembly
1. Align the connector on the bottom of the replacement riser assembly
with its mating connector on the midplane board and press down
to seat the connectors (Figure 5). The tabs on the metal riser cover
insert into the slots in the enclosure.

.
2. Attach the cable connector from the power UID assembly into the
connector on the riser assembly.
3. Reattach the top access cover by sliding the cover onto the enclosure
and tightening the cover thumbscrew.
NOTE:
The top access cover helps properly align the riser
assembly by pressing down on the raised portion of
the riser assembly bracket. Do not install the
management module until the top access cover has
been attached to the enclosure, or you may have
alignment difficulties.
4. Insert the management module into the enclosure, and push it in
until it clicks to indicate it is fully seated.
5. Reinstall the enclosure into the rack (observing the two-man lift
requirements), and reattach the enclosure front bezel.
6. Reattach all cables (Fibre Channel and/or SAS, Ethernet, power)
cables to the enclosure components.
7. Power up attached disk enclosures by pressing the power button
on the rear power UID bezel of each disk enclosure.
8. Power up the controller enclosure by pressing the power button on
the rear power UID bezel of the controller enclosure.
Verifying proper operation
NOTE:
Wait approximately five minutes for the system to check the
status of components after the enclosure is powered on.
After replacing the riser assembly, verify that the green LEDs are lit on
the management module and the power UID.
