System-Board Leds - IBM 8485E2U Installation Manual

System-board LEDs

The following illustration shows the LEDs on the system board. You might need to
refer to this illustration when solving problems with the server.
Note: The server does not contain a light path diagnostics panel.
Use the system-board LEDs to diagnose system errors. Each error LED is lit to
indicate a problem with a specific component. After a problem is corrected, its LED
will not be lit the next time that the server is restarted; if the problem remains, the
LED will be lit again. For additional information, see the Problem Determination and
Service Guide on the IBM xSeries Documentation CD.
