Overheating

A sensor on the backplane will issue a warning at 45°C. Overheating is critical at
49°C. There are several possible responses if the system overheats.
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. Check the routing of the cables and make sure all fans are present and operating
normally.
