External Chassis Fans Not Redundant

Error Class : 0x0002 | Error Code: 0x0024

Symptom

External Chassis Fans Not Redundant (Chassis %1, Location %2).

Cause

One or more fans are not functioning or have been removed.

Action

Add a fan or replace the failed fan.

Be sure the fan configuration meets the functional requirements of the server.

1. Be sure the fans are properly seated and working:
   1. Follow the procedures and warnings in the server documentation for removing the access panels and accessing and replacing fans.
   2. Unseat, and then reseat, each fan according to the proper procedures.
   3. Replace the access panels, and then attempt to restart the server.
2. Be sure the fan configuration meets the functional requirements of the server.
3. Be sure no ventilation issues exist. If the server is operated for an extended period of time with the access panel removed, airflow might be impeded, causing thermal damage to components.
4. Be sure no POST error messages are displayed while booting the server that indicate temperature violation or fan failure information.
5. Use iLO or an optional IML viewer to access the IML to see if any event list error messages relating to fans are listed.
6. In the iLO web interface, navigate to the Information > System Information page and verify the following information:
   1. Click Fans, and then verify the fan status, fan speed, and airflow requirements.
   2. Click Temperatures, and then verify the temperature readings for each location on the Temperatures tab. If a hot spot is located, check the airflow path for blockage by cables and other material. A hot spot is not an absolute temperature but is relative to a component specification. Hot spot is defined as temperature on a sensor within 3°C of a Caution threshold listed on the Temperature tab.
7. Replace any required non-functioning fans and restart the server.
8. Be sure all fan slots have fans or blanks installed. For airflow requirements, see the server documentation.
9. Verify the fan airflow path is not blocked by cables or other material.
