System-board LEDs and controls
Note: Any error LED can be lit after ac power has been removed from the
system-board tray so that you can isolate a problem. After ac power has
been removed from the system-board tray, power remains available to these
LEDs for up to 90 seconds. To view the error LEDs, press and hold the
reminder button on the system board to light the error LEDs. The error LEDs
that were lit while the system-board tray was running will be lit again while
the button is pressed.
The following illustration shows the locations of the LEDs and controls on the
system board.
