only an authorized representative conducts replacements and installation of the
processor on this server.
Note

multiprocessor configuration make sure to use a processor with the same product
number.
Important
To avoid static electricity, see Chapter 1 (1.8 Anti-static Measures) in Safety
Precautions and Regulatory Notices.
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 motherboard. Repair of the
server due to failures or damage resulted from installing such a CPU will be
charged.
Update the system ROM before installing the processor if a higher speed
processor is to be installed.
Note
Pins on the motherboard are very fragile and easily damaged. To avoid damaging
the motherboard, do not touch the processor or processor socket contact point.
Note
When handling the heat sink always hold along the fin shaft. You may damage the
fin by holding it.
Tips
After adding the CPU, Windows may record the event log to System category of
Event Viewer, but it is no problem for operation.
