Hot-Swap Power Supply Replacement
Note: If a power supply is being replaced for a redundant failure, after the service
repair action is completed, ask the customer to check the crontab file for any
power/cooling warning messages. When a power or cooling error is encountered,
AIX adds an entry to the crontab file to
″
wall
″
a warning message every 12
hours, to alert or remind the customer of the problem. Replacing the faulty part
does not clear this crontab entry, so unless the crontab file is edited to remove
this entry, the customer continues to be reminded of the failure despite its having
been repaired. Use the crontab -l command to read the crontab file to
determine if an entry exists. Use the crontab -e command to edit the file.
To replace a hot-swap power supply, do the following:
1. If you are adding a new power supply to a system that was configured with only
one power supply installed, remove the power-supply filler panel from power
supply #2 bay.
2. Grasp the handle located on top of the new power supply. Pivot the handle upward
to 90 degrees. This action puts the handle cams into the correct position to help
seat the power supply into its connector.
3. Carefully insert the power supply into the same power supply bay from which the
faulty power supply was just removed.
4. Lower the power supply handles, carefully pressing the power supply into the
connector. The spring latch located on the underside of each handle will snap into
place, indicating that the power supply is seated correctly and locked into position.
Note: Improper operation of the spring activated portion of the power supply
handles can result in the following:
v
The retractable spring remains compressed - This scenario keeps the
handle from locking the power supply in its seated position. To eliminate
this problem, lower the handle into the locked position, push the spring
activated handle end toward the locking tab. This action forces the spring
latch to mat with the locking tab in the spring latch receiver hole.
v
The locking tab receiver is bent - Before lowering the handle to lock the
power supply into the seated position, ensure that the locking tab located
on top of the power supply in the receiver hole is not bent. Before the
spring latch will seat onto the locking tab, the locking tab, if bent, must be
straightened.
