Information Panel System Error Led - IBM xSeries 230 6RY Hardware Maintenance Manual

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 (found in the
upper right corner of the processor). 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
Notes:
1. To locate the LEDs on the system board see "System board layout" on page 41.
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
Diagnostic Panel LED
All LEDs off (Check System Error
Log for error condition, then clear
System Error Log when the
problem is found.)
CPU LED on (The LED next to the
failing CPU should be on.)
VRM LED on (The LED next to
the failing VRM should be on.)
DASD1 LED on (The LED located
next to the drive bay that the
failing drive is installed in will be
turned on. Check amber drive LED
for failing hard drive.)
DASD2 LED on (The LED located
next to the drive bay that the
failing drive is installed in will be
turned on. Check amber drive LED
for failing hard drive.)
FAN LED on
MEM LED on (The LED next to
the failing DIMM is on.)
NMI LED on
PCI A LED on

LED is off, there is probably an LED problem. Run LED diagnostics.
when the system is powered down.
FRU/Action
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.
2. System Board.
1. Voltage regulator module indicated by the VRM LED on the system
board that is turned on.
2. Processor indicated by the Processor LED.
3. System Board.
1. Be sure the fans are operating correctly and the air flow is good.
2. Failing drive. SCSI channel A has failed (This is the SCSI channel for the
hot-swap hard disk drives).
3. SCSI Backplane.
1. Be sure the fans are operating correctly and the air flow is good.
2. Failing drive. SCSI channel B has failed (This is the channel for optional
CSI devices installed in the non-hot-swap bays).
3. SCSI Backplane.
1. Check individual fan LEDs.
2. Replace respective fan.
3. Fan Cable.
4. System Board.
5. Power Backplane Board.
1. System Board.
2. Failing DIMM in slot J1-J4.
1. Reboot the system.
2. Check the System Error Log.
1. PCI Card in slot 5.
2. Remove all PCI adapters from slots 1-5.
