Processor Problems - HP Tc2120 - Server - 256 MB RAM Maintenance Manual

Chapter 6
4. Run the Diagnostics for Windows utility and:
a. Verify the IDE IDs and any relevant switch settings are correct.
b. Verify the problem is the IDE bus, by looking for specific information.
5. If an accessory board was added recently, check for a resource conflict between the new board and an
existing accessory boards.
6. Also, if you have changed the options on an existing board, there may be a resource conflict:
a. Remove the new board and restart the Server.
b. If this corrects the problem, the board is either defective or it is trying to use a system resource used by
the IDE controller board.
c. Check if the board is using memory, I/O addresses, or interrupt lines that are also used by the IDE
controller board.
7. Check for any recent changes or upgrades to the software.
For example, has anyone moved, removed, or changed the configuration files or drivers? Refer to the
software documentation for more information.
8. If you suspect hardware failure and there are no system error messages or beep codes, check each
component associated with the failure.
Equipment failure is probably the most unlikely reason for a IDE devices failure.

Processor Problems

Symptoms:
•
The server is overheating.
Action:
Processor problems in the hp server tc2120 are typically problems of overheating due to incorrect installation
of the heat sink-cooling fan on the processor or a damaged thermal patch.
1. Verify that the jumper switch is set properly for the processor. See
after Processor Upgrade"
2. Remove and reseat the heat sink-cooling fan.
3. Check the condition of the existing thermal patch on the bottom of the heat sink. If it is damaged, replace
the heat sink-cooling fan.
4. Verify the cooling fan is connected to its power connector properly and there is voltage to the fan.
5. Remove and reseat the processor, ensuring the ZIF lever is completely down.
6. Replace each of the following components (one at a time) with a known good component, and retest the
server:
o Heat sink-cooling fan (with a good thermal patch)
o Processor
CAUTION Do not push on the processor components; push only on the
edge. Pushing on the device may damage it.
7. If the fault persists, replace the system board.
