Information-panel system error LED
The system error LED is turned on when an error is detected. If the system error
LED is on, remove the cover and check the diagnostic panel LEDs. Table 21 on
page 127 contains a complete list of diagnostic panel LEDs followed by the part or
action required to correct the problem. This table is valid only when the system
error LED is on.
Notes:
1. If a diagnostic panel LED is on and the information-LED panel system error LED
is off, there is probably an LED problem. Run LED diagnostics.
