Troubleshooting fan modules

How to troubleshoot the fan modules.

About this task

When one or more fans are not working, turn off the appliance as soon as possible to avoid overheating. The remaining fans might not be able to maintain the appropriate environmental temperature.

Procedure

  1. View sensor status.
    • From the CLI, enter show sensors-fans.
    • In the GUI search field, enter sensors and click Fan Sensors.
    • If the output shows that all fans are running at 0 RPM, the fan module is not seated correctly in the appliance.
    • If the output shows that one or more fans are running at less than 1200 RPM, contact IBM® Support.
  2. View the fan module LED.
    If steady, the fan is operating at less than 1200 RPM or a fault exists.

What to do next

If the module is not seated correctly, remove and reinsert the module.

If you believe that the module must be replaced, contact IBM Support.
