Table 1. Light path diagnostics.
LED
None The system error log is 75% or more full; a PFA alert was logged; or a failure occurred
on the I2C bus.
SMI A systems management event occurred.
NMI A nonmaskable interrupt occurred. The PCIA, PCIB, or PCIC LED will probably also
be on.
SP The service processor has failed.
PCIA An error occurred on PCI bus A. An adapter in PCI slot 1 or 2, or the processor board
caused the error.
PCIB An error occurred on PCI bus B. An adapter in PCI slot 3, 4, 5, or 6 or the processor
board caused the error.
PCIC An error occurred on PCI bus C. An error on the processor or I/O board caused the
problem.
DASD A hot-swap hard disk drive has failed on SCSI channel B.
MEM A memory error occurred.
CPU One of the microprocessors has failed or a microprocessor is installed in the wrong
connector.
VRM One of the voltage regulator modules on the processor board has failed.
FAN One of the fan assemblies has failed or is operating too slowly.
Note:
TEMP The system temperature has exceeded the maximum rating.
NON RED Server drawing too much power to operate in a redundant power mode.
OVER SPEC The server is drawing more power than the power supplies are rated for.
PS1 The first power supply has failed.
PS2 The second power supply has failed.
PS3 The third power supply has failed.

Cause
A failing fan can also cause the TEMP and DASD LEDs to be on.
Check the system error log and correct any problems. See "Choices available from the Configuration/Setup
main menu" on page 44 for information about clearing the error log. Disconnecting the server from all power
sources for at least 20 seconds will turn off the system error LED.
Restart the server.
1. If the PCIA, PCIB, or PCIC LED is not on, restart the server.
If the problem persists, try to determine the failing adapter by removing one adapter at a time and restarting the
server after each adapter is removed.
1. Run service processor diagnostics.
2. Replace Legacy I/O board.
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 PCI bus A (PCI slots 1–2) and restarting the server after
each adapter is removed.
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 PCI bus B (PCI slots 3–6) and restarting the server after
each adapter is removed.
Check the error log for additional information. If the error log indicates a problem with the integrated SCSI
controller, the Ethernet controller or video controller, see "Starting the diagnostic programs" on page 25.
1. If the TEMP LED is also on, take the actions listed for that LED.
2. If the amber status LED on one of the hot-swap hard disk drives is on, replace the drive.
1. Check the DIMM error LEDs on the memory board.
2. Replace the DIMM indicated by the lit DIMM error LEDs.
1. Check the microprocessor error LEDs on the memory board. If a microprocessor error LED is on for a
microprocessor connector that has a terminator card installed instead of a microprocessor, the
microprocessors are not installed in the correct order. See "Installing a microprocessor kit" on page 73
for information about the correct order for installing microprocessors and VRMs. Otherwise, continue
with the next step.
2. Turn off the server, reseat the microprocessor indicated by the lit microprocessor error LED, and restart
the server.
3. If the problem persists, replace the microprocessor.
1. Check the VRM error LEDs on the processor board.
2. Turn off the server, reseat the VRM indicated by the lit VRM error LED, and restart the server.
3. If the problem persists, replace the VRM.
The LED on the failing fan assembly will be lit. Replace the fan assembly.
1. Check to see if a fan has failed. If it has, replace the fan.
2. Make sure the room temperature is not too high. (See "Features and specifications" on page 3.)
If the problem persists, see "Temperature checkout" on page 31.
System can continue to operate in a nonredundant power mode. To operate in a redundant mode, add a power
supply or remove most recently installed options.
Either add a power supply or remove a device from the server.
Replace the first power supply.
Replace the second power supply.
Replace the third power supply.
