System-board LEDs

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

You must remove the blade server from the BladeCenter unit, open the cover or remove any optional expansion units, and press the power-control button (see Blade server controls and LEDs) 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.

The following illustration shows the LEDs on the system board.
