Microprocessor problems - IBM NeXtScale nx360 M4 Compute Node

Use this information to solve microprocessor problems.

The microprocessor's symptoms and actions table with one level of row and column headers.

Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained technician. Go to the IBM support website at the IBM support portal to check for technical information, hints, tips, and new device drivers or to submit a request for information.
The server goes directly to the POST Event Viewer when it is turned on.	Correct any errors that are indicated by the light path diagnostics LEDs (see Light path diagnostics). Make sure that the server supports all the microprocessors and that the microprocessors match in speed and cache size. To view the microprocessor information, run the Setup utility and select System Information > System Summary > Processor Details. (Trained technician only) Make sure that microprocessor 1 is seated correctly. (Trained technician only) Remove microprocessor 2 and restart the server. Replace the following components one at a time, in the order shown, restarting the server each time: (Trained technician only) Microprocessor (Trained technician only) System board
