Replacing a power supply
A power supply can be replaced without shutting down the system.
!
WARNING:
WARNING:
A power supply must always occupy bays 0 and 1. If a power supply in
bay 0 or 1 fails, you must leave the failed power supply in its bay until you
are able to install a functioning replacement power supply. A failed power
supply in bay 0 or 1 continues to act as an air baffle, channeling airflow to
cool the bottom row of disk drives in the disk cage. Replace the failed power
supply as soon as possible to regain power redundancy.
To replace a power supply:
1. Identify the power supply that you want to remove. See Power supply LEDs on
page 175 for information about diagnosing power supplies.
2. Release the AC power cord from the strain-relief tie-wrap on the power supply. Press
the tab on the head of the tie-wrap to release it. See the following figure.
3. Unplug the AC power cord from the power supply.
