Use the system-board LEDs to diagnose system errors. An error LED is lit to
indicate a problem with a specific component. After a problem is corrected, the 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 Hardware Maintenance
Manual.
