Fan Assembly Fault Indicators

Use one of the following methods to determine if a fan assembly is faulty:
•
Check the fan status LED.
–
Steady amber – fan assembly has a failure (full or partial).
–
Slow-flashing amber (on 2 seconds, then off 2 seconds) – fan assembly is not seated correctly or is faulty.
–
Fast-flashing amber (on ½ second, then off ½ second) – environmental range exceeded.
•
Enter fanShow . If the status of the fan assembly displays absent or faulty, check if the assembly is seated in the
chassis. If it is seated, the power supply could be faulty or is not receiving power for some reason.
•
Enter sensorShow to determine if a fan is running above average temperatures of other installed fan(s).
•
Enter errDump to display the system error log.

Fan Assembly Task Guide

This section addresses the steps for installing or replacing fan assemblies when the chassis is running (hot-swap) or must
be powered off (cold-swap). References are provided for more details on removal and installation steps.
NOTE
Each fan assembly contains 3 fans for a total of 6 fans for three installed fan assemblies. The chassis requires 5
fans out of 6 functioning fans for operation. If hot-swapping a fan assembly, be sure to have the replacement fan
assembly ready to install before removing a faulty fan assembly and replace as soon as possible.
NOTE
If a fan assembly has failed, do not remove it from the chassis unless an FRU is available for replacement. If the
slot is left empty for an extended time period, this could cause chassis air leakage and overheating.
NOTE
Make sure that captive screws securing fan assemblies to the chassis are tightened. If the screws are not
tightened, high pressure from fan operation may unseat the fan from chassis connectors.
Replacing a Fan Assembly (Hot-Swap)
If your chassis is up and running, but a fan assembly has failed, complete the following steps:
1. Remove fan assembly.
2. Insert new fan assembly into the empty slot as soon as possible.
3. Verify that the fan assembly status LED is green.
Replacing a Fan Assembly (Cold-Swap)
If your chassis is up and running, but you want to power down the chassis to replace a failed fan assembly, complete the
following steps:
1. Shut down the system using the sysShutdown command.
2. Unplug power cords from receptacles on all power supply assemblies.
3. Remove faulty fan assembly.
4. Insert new fan assembly.
5. Plug the power cords into the all power supply assemblies from the power sources to the power chassis on.
