Microprocessor problems

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See the parts listing in the Hardware Maintenance Manual to determine which components are customer

replaceable units (CRUs) and which components are field replaceable units (FRUs).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.

Symptom Action

The server emits a continuous

beep during POST, indicating

that the startup (boot)

microprocessor is not working

correctly.

1. Correct any errors that are indicated by the system board LEDs (see

“System-board LEDs” on page 22).

2. Make sure that the server supports all the microprocessors and that the

microprocessors match in speed and cache size.

3. (Trained service technician only) Reseat microprocessor 1.

4. (Trained service technician only) If there is no indication of which

microprocessor has failed, isolate the error by testing with one microprocessor

at a time.

5. Replace the following components one at a time, in the order shown, restarting

the server each time:

a. (Trained service technician only) Microprocessor 2

b. VRM 2

c. (Trained service technician only) System board

6. (Trained service technician only) If multiple error codes indicate a

microprocessor error, reverse the locations of two microprocessors to determine

whether the error is associated with a microprocessor or with a microprocessor

socket.

v If the error is associated with a microprocessor, replace the microprocessor.

v If the error is associated with a VRM, replace the VRM.

v If the error is associated with a microprocessor socket, replace the system

board.
