System-board LEDs

Use this information to locate system-board LEDs in the blade server.

The following illustration shows the LEDs on the system board.

You must remove the blade server from the BladeCenter unit, open the cover or remove any optional expansion units, and press the light path diagnostics switch (see System-board switches) to light any error LEDs that were turned on during processing. Diagnosing problems using the light path diagnostic LEDs is described in Light path diagnostics.
Note
Some system boards are not equipped with the power jumper bad LED.
