None, but the Check Log LED is lit. |
An error has occurred and cannot be isolated.
The error is not represented by a path. |
- Check the IMM2 system even log and the system-error log for information
about the error.
- Save the log if necessary and clear the log afterwards.
|
System Error LED |
An error occurred. |
- Check the light path LEDs and follow the listed instruction.
- Check the IMM2 system even log and the system-error log for information
about the error.
- Save the log if necessary and clear the log afterwards.
|
OVER SPEC |
The power supplies are using more power than
their maximum rating. The system is drawing power incoherent to power
supply specified ratings. |
If the OVER SPEC LED is lit, use one of the
following procedures:
- Turn off the server, disconnect the power from the server.
- Remove the optical drive, fans, hard disk drives, and hard disk
drive backplanes.
- Restart the server to see whether the problem remains.
- Reinstall each device that was removed in step 2 one at a time,
starting the server each time, to isolate the failing device.
- Replace any failing device.
- (Trained technician only) Replace the system board.
|
LINK |
Reserved. |
|
PS |
A power supply is not detected or has failed. |
- Check the power-supply in the server that has an lit yellow LED
(see Power-supply LEDs).
- Make sure that the power supplies are seated correctly.
- Remove one of the power supplies to isolate the failed power supply.
- Replace the failed power supply.
|
PCI |
An error has occurred on a PCI card, a PCI bus
or on the system board. An additional LED is lit on one of the riser
cards. |
- Check the system-event log for information about the error.
- Check the LEDs on the PCI riser cards to identify the component
that caused the error.
- If you cannot isolate the failing adapter by using the LEDs and
the information in the system-event log, remove one adapter at a time
from the failing PCI bus; and restart the server after each adapter
is removed.
- Replace the following components, in the order shown, restarting
the server each time:
- PCI riser card
- (Trained technician only) Replace the system board.
|
FAN |
A fan has failed, is operating too slowly, or
has been removed. The TEMP LED might also be lit. |
- Check the LEDs on the server.
- Reseat the failing fan, which is indicated by a lit LED on the
fan.
- Replace the failing fan.
|
TEMP |
The system temperature has exceeded a threshold
level. A failing fan can cause the TEMP LED to be lit. |
- Make sure that the air vents are not blocked.
- Determine whether a fan has failed. If it has, replace it.
- Make sure that the heat sink is seated correctly.
- Make sure that the room temperature is not too high. See Server features and specifications and System reliability guidelines for the server temperature information.
|
MEM |
An invalid memory configuration (both the MEM
LED and CONFIG LED might be lit) or a memory error has occurred . |
Note: Each time you install or remove a DIMM,
you must disconnect the server from the power source; then, wait 10
seconds before restarting the server.
- If the MEM LED and the CONFIG LED are lit, the system issues an
invalid memory configuration error. Complete the following steps to
correct the problem:
- Check the system-event log in the Setup utility or IMM error messages.
Follow steps indicated in UEFI (POST) error codes and Integrated Management Module II (IMM2) error messages.
- If the CONFIG LED is not lit, the system has detected a memory
error. Complete the following steps to correct the problem:
- Update the firmware to the latest level (see Updating the firmware).
- Reseat or swap the DIMMs.
- Check the system-event log in the Setup utility or IMM error messages.
Follow steps indicated in UEFI (POST) error codes and Integrated Management Module II (IMM2) error messages.
|
NMI |
A nonmaskable interrupt has occurred, or the
NMI button was pressed. |
Check the system-event log for information about
the error. |
CONFIG |
A hardware configuration error has occurred. |
- If the CONFIG LED and the CPU LED are lit, complete the following
steps to correct the problem:
- Check the microprocessors that were just installed to make sure
that they are compatible with each other (see Replacing a microprocessor and heat sink for additional
information about microprocessor requirements).
- (Trained technician only) Replace the incompatible microprocessor.
- Check the system-event logs for information about the error. Replace
any components that are identified in the error log.
- If the CONFIG LED and the MEM LED are both lit, complete the following
steps:
- Make sure that the DIMM configuration is supported (see Installing a memory module for
DIMM requirements and installation sequence information).
- Replace the DIMMs with a supported configuration.
|
CPU |
An invalid microprocessor configuration or a
microprocessor has failed (both the CPU LED and the CONFIG LED might
be lit). |
- If the CONFIG LED is lit, the system issues an invalid microprocessor
configuration error. Complete the following steps to correct the problem:
- Check the microprocessors that were just installed to make sure
that they are compatible with each other (see Replacing a microprocessor and heat sink for additional
information about microprocessor requirements) and use the Setup utility
and select System Information → System Summary → Processor to
verify the microprocessors information.
- (Trained technician only) Replace the incompatible microprocessor.
- Check the system-event logs for information about the error. Replace
any components that are identified in the error log.
- If the CPU LED is lit and the CONFIG LED is not lit, complete
the following steps:
- (Trained technician only) Make sure that the failing microprocessor,
which is indicated by a lit LED on the system board, is installed
correctly. See Replacing a microprocessor and heat sink for information
about installation and requirements.
|
When only the CPU LED is lit, a microprocessor
has failed. |
If the CONFIG LED is not lit, a microprocessor
failure occurs, complete the following steps to correct the problem:
- (Trained technician only) Make sure that the failing microprocessor
and its heat sink, which are indicated by a lit LED on the system
board, are installed correctly. See Replacing a microprocessor and heat sink for information
about installation and requirements.
- (Trained technician only) Replace the failing microprocessor (see Removing a microprocessor and heat sink and Replacing a microprocessor and heat sink).
- For more information, go to the IBM Service website.

HDD |
A hard disk drive has failed or is missing. |
- Check the LEDs on the hard disk drives for the drive with a lit
status LED and reseat the hard disk drive.
- Make sure that the cables are correctly connected to the hard
disk drive backplane.
- For more information, see Hard disk drive problems.
- If the error remains, replace the following components in the
order listed, restarting the server after each:
- Replace the hard disk drive.
- Replace the hard disk drive backplane.
- If the error remains, replace the following components one at
a time, in the order listed, restarting the server after each:
- Replace the hard disk drive.
- Replace the hard disk drive backplane.
- If the problem remains, go to the IBM Service website.
|
BOARD |
An error has occurred on the system board. |
- Check the LEDs on the server.
- Check the LEDs on the system board to identify the component that
caused the error. The BOARD LED can be lit due to any of the following
reasons:
- Battery
- Missing PCI riser-card assembly
- Failed firmware update
- Failed system board
- Check the system-event log for information about the error.
- Replace any failed or missing replacement components, such as
the battery or PCI riser-card assembly.
- (Trained technician only) replace the server system board.
