Replace a Pilot Power Supply
P
ower supplies, which exist in pairs, provide DC to all of the Pilot components. If
one power supply fails, the other supply carries the full load. This situation
creates a risk of Pilot failure should the other power supply also fail.
Prerequisites:
•
Before handling a component, touch a grounded surface to discharge any
static electricity.
• Aach an electrostatic discharge (ESD) wrist strap to your wrist, and stand
on an ESD mat while replacing components.
• Ensure that you have a similar replacement power supply available before
you start the replacement procedure.
• Initiate Guided Maintenance only when you are able to replace the power
supplies immediately.
Each Pilot has a pair of power supplies that are located at the back of the Pilot.
P
ower supplies are customer replaceable units (CRUs). Replacing a failed power
supply does not require you to bring the Pilot oine, provided that the other
power supply is online and working. The following gure shows the location of
the Pilot power supplies.

Note: To replace a power supply, the left side of the CMA must be disengaged
from the end of the slide before the power supply can be pulled out. Disengaging
the CMA reduces the risk of damaging the cables.
Important: Do not remove the failed power supply until you have a replacement
power supply to ensure proper airow in the Pilot.
Note: After you have replaced power supply (PS–0), you must reset the Oracle
ILOM service processor (SP) to propagate the key identity properties (KIP) data
to the new power supply. Power supply (PS–1) does not contain KIP data, and
therefore does not require an SP reset after replacement.
