General fan problems are occurring
Action:
1. Be sure the fans are properly seated and working.
a. Follow the procedures and warnings in the server documentation for
removing the access panels and accessing and replacing fans.
b. Unseat, and then reseat, each fan according to the proper procedures.
c. Replace the access panels, and then attempt to restart the server.
2. Be sure the fan configuration meets the functional requirements of the server.
Refer to the server documentation.
3. Be sure no ventilation problems exist. If you have been operating the server
for an extended period of time with the access panel removed, airflow may
have been impeded, causing thermal damage to components. Refer to the
server documentation for further requirements.
4. Be sure no POST error messages ("POST Error Messages and Beep Codes"
on page 204
) are displayed while booting the server that indicate temperature
violation or fan failure information. Refer to the server documentation for the
temperature requirements for the server.
5. Access the IML to see if any event list error messages (on page 232
) are
listed relating to fans.
