Microprocessor Problems; Monitor Problems - Lenovo ThinkServer RD230 Hardware Maintenance Manual

• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See the parts listing in Chapter 7 "Parts listing, RD230 Types 1043, 1044, 4010, and 4011" on page 91 to
determine which components are customer replaceable units (CRUs) and which components are field
replaceable units (FRUs).
• If an action step is preceded by "(Trained service technician only)," that step must be performed only by
a trained service technician.

Microprocessor problems

• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See the parts listing in Chapter 7 "Parts listing, RD230 Types 1043, 1044, 4010, and 4011" on page 91 to
determine which components are customer replaceable units (CRUs) and which components are field
replaceable units (FRUs).
• If an action step is preceded by "(Trained service technician only)," that step must be performed only by
a trained service technician.
Symptom
The server emits a continuous
beep during the POST,
indicating that the startup
(boot) microprocessor is not
working correctly.

Monitor problems

Some monitors have their own self-tests. If you suspect a problem with your monitor, see the documentation
that comes with the monitor for instructions for testing and adjusting the monitor.
Action
3. Return the removed DIMMs, one pair at a time, to their original connectors,
restarting the server after each pair, until a pair fails. Replace each DIMM in the
failed pair with an identical known good DIMM, restarting the server after you
reinstall each DIMM. Replace the failed DIMM. Repeat step 3 on page 15 until
you have tested all removed DIMMs.
4. (Trained service technician only) Replace the system board.
Action
1. Make sure that the server supports all the microprocessors and that the
microprocessors match in speed and cache size.
2. (Trained service technician only) Reseat microprocessor 1.
3. (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.
4. 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
5. (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.
• If the error is associated with a microprocessor, replace the microprocessor.
• If the error is associated with a VRM, replace the VRM.
• If the error is associated with a microprocessor socket, replace the system
board.
