DIMM Slot LED Blink Codes = LED on = LED off Alternating Blink Code: LED LED LED LED 01 23 LED Error Codes Error Condition Corrective Action Primary VRM Failure Check that primary voltage regulator module (VRM) is correctly seated. If problem persists, replace VRM. Secondary VRM Failure Check that secondary VRM is correctly seated. If problem persists, replace VRM. Processor OverTemperature Check fan for function. Turn off system, wait 20-25 minutes for system to cool, and restart system. Processor or Terminator Board Not Installed Install processor in primary processor socket and a processor or terminator board in secondary processor socket. DIMM Status Error Codes When no processor error condition exists, each diagnostic LED display the status of the DIMM in the corresponding socket, as follows: • OFF: no DIMM installed • Flashes ON and OFF at 1 Hz in 50/50 proportion of time: defective or inappropriate DIMM • Flashes ON and OFF at 1 Hz in 90/10 proportion of time: non-HP DIMM installed • ON: HP DIMM installed 95

Error Condition
Corrective Action
Primary VRM Failure
Check that primary voltage regulator module
(VRM) is correctly seated. If problem persists,
replace VRM.
Secondary VRM
Failure
Check that secondary VRM is correctly
seated. If problem persists, replace VRM.
Processor Over-
Temperature
Check fan for function. Turn off system, wait
20-25 minutes for system to cool, and restart
system.
Processor or
Terminator Board Not
Installed
Install processor in primary processor socket
and a processor or terminator board in
secondary processor socket.
DIMM Status Error Codes
When no processor error condition exists, each diagnostic LED display the status of the DIMM in the
corresponding socket, as follows:
•
OFF: no DIMM installed
•
Flashes ON and OFF at 1 Hz in 50/50 proportion of time: defective or inappropriate DIMM
•
Flashes ON and OFF at 1 Hz in 90/10 proportion of time: non-HP DIMM installed
•
ON: HP DIMM installed
