Processor (CPU)
The server may have another CPU installed in addition to the factory-installed CPU (Intel® Xeon® Processor).
Important
•
The CPU to be added must have the same specification (the core voltage,
clock, and others) as the CPU already installed.
•
The CPU is extremely sensitive to static electricity. Make sure to touch the
metal frame of the server to discharge static electricity from your body before
handling the CPU. Do not touch the CPU pins by a bare hand or place the CPU
directly on the desk. For static notes, refer to “Handling precautions (for
Anti-static Measures)”.
•
Do not operate the system until confirming that the additionally installed CPU
is in normal state.
•
Make sure to use the CPU authorized by NEC. Installing a third-party CPU may
cause a failure of the CPU as well as the server. Repair of the server due to
failures or damage resulted from installing such a CPU will be charged.
Tips
If the different revision of the processors are installed in the multiprocessor system,
Windows logs the following information in system log of Event Viewer. However, this event
does not affect the system operation.
