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

1. Use the LEDs to determine the nature of the overheating condition.
2. Confirm that the chassis covers are installed properly.
3. Check the routing of the cables and make sure all fans are present and operating
normally.
4. Verify that the heatsinks are installed properly.
