1. If your system does not have a redundant (third) power supply installed, turn off the
power to the system and peripheral devices. Otherwise, go to the next step.
2. To remove the power supply (1):
a. Unplug the power cord connector from the power supply.
Attention:
Be careful when you remove the hot-swap power supply; the power
supply might be too hot to handle comfortably.
b. Remove the defective power supply by placing the handle (5) on the power
supply in the open position (perpendicular to the power supply) and pulling the
power supply from the bay.
3. If you are not replacing the power supply:
a. Install a power-supply filler panel (2).
Note: During normal operation, each power-supply bay must have either a
power supply or filler panel installed for proper cooling.
b. Open the cable-restraint bracket (3) and remove the power cord from the
cable-restraint bracket. Close the cable-restraint bracket.
c. Unplug the power cord from the electrical outlet.
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, alerting/reminding 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 will continue to be reminded of the failure despite it’s
having been repaired. The AIX command crontab -l reads the crontab file to
determine if an entry exists. The crontab -e command edits the file.
