Checking the Server Air Flow
•
Make sure there are no objects to obstruct airflow in and out of the server.
•
If you are using a front bezel, make sure the bezel filter is replaced periodically.
•
Do not operate the server without drives or drive trays in the drive bays.
•
Use only recommended server parts.
•
Make sure no wires or foreign objects obstruct air flow through the chassis. Pull all excess
cabling out of the airflow path or use shorter cables.
The control panel LEDs display system heat status. See “Control Panel” in
details.
Overheating
There are several possible responses if the system overheats.
Overheat Temperature Setting
Some backplanes allow the overheat temperature to be set at 45, 50, or 55 by changing a
jumper setting. For more information, consult the backplane user manual at www.supermicro.
com. (Click Support, then the Manuals link.)
Responses
If the server overheats:
1. Use the LEDs to determine the nature of the overheating condition.
2.
Confirm that the chassis covers are installed properly.
3. Make sure all fans are present and operating normally.
4. Check the routing of the cables.
5. Verify that the heatsinks are installed properly.
