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.
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 component locations" on page 54.
2. Check the System Error Log for additional information
before replacing a FRU.
3. It may be necessary to view the System Error Log from
a remote connection, such as MOST.
4. The memory card DIMM error LEDs and processor
error LEDs turn off when the system is powered down.
Note: The System Error LED will also be on.

1. System Error Log is 75% full;
clear the log.
2. Bad, missing or mis-installed
processor terminator; remove and
reinsert terminator.
3. PFA alert; check Netfinity log for
failure; clear PFA alert; remove
AC power for at least 20 seconds,
reconnect, then power up system.
4. Run Information Panel
diagnostics.
1. Insure terminator (or processor
if multiprocessor system) is
installed in slot D. See
"Installing a microprocessor kit" on
page 81.
2. Processor 1, 2, 3, or 4
3. System Board.
1. Be sure the fans are operating
correctly and the air flow is
good.
2. Failing drive.
