System Upgrade 8-25
PROCESSOR (CPU)
In addition to the standard CPU (Intel® Xeon® Processor), you can add one CPU to make a
multi-processor system.
IMPORTANT:
 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 terminals or onboard parts with a bare hand or place the CPU directly on the desk. For
more information on static electricity, see “ANTI-STATIC MEASURES.”
 Do not use the system before checking to see it works correctly.
 Make sure to use the CPU specified by NEC. Installing a third-party CPU may cause a failure
of the CPU as well as the server.
 Before adding or removing a CPU, power off the server and then remove the CPU/IO module.
 Make sure to read "ANTI-STATIC MEASURES" and "PREPARING YOUR SYSTEM FOR
UPGRADE" before starting installing or removing options.
