Note: See “System replaceable units” on page 144 to determine which components should be replaced by a field
service technician.
Diagnostics panel lit LED FRU/action
NMI (non-maskable interrupt occurred)
v
Check the system-error log and the BMC log for information about the
error.
S_ERR (soft error)
1. Restart the server.
2. Update firmware and adapter drivers.
3. Check the POST error log for information.
4. System board.
TEMP (temperature exceeded a threshold
level)
Note: The FAN LED might also be lit.
1. Make sure that all fans are operating correctly.
2. Ambient temperature must be within normal operating specifications;
see “Features and specifications” on page 3.
3. System board.
FAN (a fan failed or is operating slowly)
Note: The TEMP LED might also be lit.
1. Check individual fan LEDs.
2. Failing fan.
3. System board.
MEM (memory failure (LED next to the
failing DIMM is on))
1. Run Configuration/Setup Utility program and make sure DIMMs
are correctly configured.
2. Failing DIMM.
3. System board
CPU (microprocessor failure (LED next to
the failing microprocessor is on))
1. Failing microprocessor
2. System board
PCI (PCI error; LED on system board at
failing adapter will also be lit)
1. Failing adapter.
2. System board.
VRM (VRM or integrated VRD failed (LED
next to the failing VRM is on))
1. Remove ac power from the server for 20 seconds, then
reconnect power and restart the server.
2. If LED next to VRM is lit, replace pluggable VRM.
3. If LED next to integrated VRD is lit, replace the system board.
DASD /RAID (hard disk drive failure
(check drive LED) or RAID failure (check
LEDs)
Note: This LED will also be lit when a
hard disk drive is removed from the server.
1. Be sure the fans are operating correctly and the airflow is good
so that the drive is not overheating.
2. Hard disk drive.
3. SCSI backplane.
4. System board.
SERVICE PROCESSOR BUS (service
processor error)
1. Remove ac power from the server for 20 seconds, then
reconnect power and restart the server.
2. System board.
EVENT LOG (system warning has
occurred)
v Check system-error log and BMC log for information about the
error.
CPU/VRM mismatch (microprocessor
does not match VRM or VRD)
1. Install a matched microprocessor and VRM.
2. System board
