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. The following is a
complete list of diagnostic panel LEDs followed by the FRU/Action for correcting the
problem. The following chart is valid only when the system error LED is on.
Note: 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.
Notes:
1. To locate the LEDs on the system board see "System board LED locations" on
page 44.
2. Check the System Error Log for additional information before replacing a FRU.
3. The DIMM error LEDs, processor error LEDs, and VRM error LEDs turn off when
the system is powered down.
1. System Error Log is 75% full; clear the log.
2. PFA alert; check Netfinity log for failure; clear PFA alert; remove AC power
for at least 20 seconds, reconnect, then power up system.
3. Run Information Panel diagnostics.
1. Processor 1 or 2.
