LED Diagnostics:
The diagnostics built into the server allow you
to quickly identify the type of system error that occurred. When the System Error LED on the
information LED panel is illuminated, use the following information to isolate the problem.
An error message usually appears on the display monitor as well.
System Board LED
Description
Service Processor
An error has occurred in the service processor.
Error LED On
Actions:
1. Try a reset by turning off the system, jumper/short J39,
and turn on the system.
2. Replace the system board.
NMI LED on
A non-maskable interrupt occurred.
The PCI 1 or PCI 2 LED will probably also be on.
Actions:
1. If the PCI 1 or PCI 2 LED is on, follow the instructions
for those LEDs.
2. If the PCI 1 or PCI 2 LED is not on, restart the server.
If the problem persists (the NMI LED stays on), go to
'General Checkout'.
SMI LED on
A system-management interrupt occurred.
This is an indication of service processor activity, and is
not an error.
Actions: No action is required.
PCI 1 LED on
An error occurred on PCI bus 0.
An adapter in PCI slot 5 or the system board caused the error.
Actions: Check the error log for additional
information. If the error log indicates a problem with the
integrated Ethernet controller, replace the system board.
PCI 2 LED on
An error occurred on PCI Bus 1.
An adapter in PCI slot 1, 2, 3, or 4 or the system board
caused the error.
Actions:
1. Check the error log for additional information.
2. If you cannot correct the problem from the information
in the error log, try to determine the failing adapter
by removing one adapter at a time from the secondary PCI bus
(PCI slots 1-4) and restarting the server after each
adapter is removed.
DIMM 1 Error LED on
The DIMM in DIMM slot 1 has failed.
Action: Replace the DIMM in DIMM slot 1.
DIMM 2 Error LED on
The DIMM in DIMM slot 2 has failed.
Action: Replace the DIMM in DIMM slot 2.
DIMM 3 Error LED on
The DIMM in DIMM slot 3 has failed.
Action: Replace the DIMM in DIMM slot 3.
DIMM 4 Error LED on
The DIMM in DIMM slot 4 has failed.
Action: Replace the DIMM in DIMM slot 4.
FAN 1 LED on
Fan 1 has failed or is operating too slowly.
Note: A failing fan can also cause the
TEMP and DASD 1 LEDs to be on.
Action: Replace fan 1.
FAN 2 LED on
Fan 2 has failed or is operating too slowly.
Note: A failing fan can also cause the
TEMP and DASD 1 LEDs to be on.
Action: Replace fan 2.
TEMP LED on
The system temperature has exceeded the maximum rating.
Actions:
1. Check to see if a fan has failed. If it has, replace the fan.
2. Make sure the room temperature is not too hot.
Integrated Voltage
The voltage regulator for the primary microprocessor slot has failed.
Regulator Error LED on
Actions: Replace the system board.
Secondary Processor
The voltage regulator module (VRM) for the secondary microprocessor
VRM Error LED on
slot has failed.
Actions:
1. Turn off the server, reseat the VRM, and restart the server.
2. If the problem persists, replace the VRM.
Primary Microprocessor
The microprocessor in the primary microprocessor slot has failed.
Error LED on
Actions:
1. Turn off the server, reseat the microprocessor, and restart the
server.
2. If the problem persists, replace the microprocessor.
Secondary
Microprocessor Error
The microprocessor in the secondary microprocessor slot has failed.
LED on
Actions:
1. Turn off the server, reseat the microprocessor and VRM, then
restart the server.
2. If the problem persists, replace the microprocessor.
Power Supply 1 LED on
The primary power supply has failed.
Action: Replace the primary power supply replaced.
Power Supply 2 LED on
The secondary power supply has failed.
Action: Replace the secondary power supply.
System Error LED
The diagnostics have not detected a system error.
on the information
LED panel on the front
of the server is off.
DASD 1 LED on
A hot-swap hard disk drive has failed.
Actions:
1. Check the error log for additional information. If the
error log indicates a temperature problem and the fans are
working correctly, check the system for proper air flow.
2. If the amber Hard Disk Status LED on one of the hot-swap
hard disk drives is on, replace the hard disk drive.
