Cpu/Io Module; Precautions - NEC Express5800 320Fd-MR User Manual

8-6 System Upgrade

CPU/IO MODULE

To replace devices such as CPU (processor, DIMM (memory) or PCI card, you need to remove the
CPU/IO module.
IMPORTANT:

Ask your sales agent to replace the CPU/IO module and components of the CPU/IO module.
Make sure to read "ANTI-STATIC MEASURES" and "PREPARING YOUR SYSTEM FOR

UPGRADE."

To install or remove CPU or DIMM, first power off the server before removing the CPU/IO
module.

Removing the module under operation may cause unexpected trouble. Use the management
software (e.g., ftServer Utility or NEC ESMPRO Manager) to identify the module to be removed
so that the module is removed when it is stopped, without fail.
Then remove the relevant module after verifying the Status LED on the CPU/IO module. See
Chapter 2 "LEDs" for details of the Status LED.

Precautions

When replacing both CPU/IO modules, replace one module and wait until dual configuration is
established to replace the other module. If you replace the both modules simultaneously, establishing
dual CPU/IO module configuration may fail and result in interruption of the whole system.
