Replacing a Hot-Swap System Fan
Notes:
1. The Linux operating system does not support these hot-pluggable procedures. A system with Linux
installed must be shut down and powered off before installing a fan.
2. This note applies only to systems running the AIX operating system. If a fan assembly is being
replaced for a redundant failure, after the service repair action is completed, 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 system fan, do the following:
1. Pull up on the orange locking knob on the replacement fan to ensure that it is in the unlocked position.
2. Align the fan with the slot in the fan tray assembly with the fan power plug over the connector.
3. Place the fan into the fan tray.
4. Press down on the fan to ensure that the power plug is connected.
Note: The fan starts to run when the power plug connects.
5. Press the locking knob down until you feel it lock into place.
