Front Panel LEDs

Front panel LEDs provide your first indication if there is a problem with your system. Usually, a front panel LED is not the sole indication of a problem. Error messages and even other LEDs can help to isolate the problem further.

The front panel has a general fault indicator that lights whenever POST or OBDiag detects any kind of fault. It addition, it has LEDs that indicate problems with the internal disk drives, power supply subsystem, or fans. See "About the Status and Control Panel" for more information on these LEDs and their meanings.
