Fan Problems
1. Be sure there is proper ventilation. Refer to your server’s user
documentation for further requirements.
IMPORTANT: For good airflow, keep all access panels closed whenever possible.
2. Check any Power-On Self-Test (POST) messages for temperature
violation or fan failure information. Refer to your server’s user
documentation for Temperature Requirements for your server.
3. If possible, access the Integrated Management Log. See “Integrated
Management Log” in Chapter 4.
4. Verify that all fans are properly seated and working.
5. Replace any required non-functioning fans and restart the server. Refer
to your server’s user documentation for specifications on fan
requirements.
6. Verify that ALL fan slots have fans or blanks installed. Refer to your
server’s user documentation for requirements.
For systems with hot-plug fans, also:
7. Check the LEDs.
8. If the system powers on, has two long beeps and two short beeps, briefly
displays “1611-Fan failure detected,” and then the system shuts down,
check the fans.
a. Make sure that all required fans are installed properly. When power
comes on, the green LED on the top of the fan assembly comes on
and stays on. An amber fan LED indicates a fan failure.
b. Install all required working fans.
9. Follow your server’s user documentation procedures on removing the
access panels, accessing fans and replacing fans.
a. Check there also for your fan functional requirements.
b. Verify that the fans are properly seated.
c. Replace the access panels and attempt to restart the server.
10. If the above steps do not correct the server problem, see the section
“Contacting Compaq” in Chapter 1.
NOTE: For servers with redundant fans, backup fans may spin up periodically to test
functionality. This is a part of normal redundant fan operation.
