CPU/IO Module
To replace a CPU (processor), DIMM (memory), or PCI card, you need to remove the CPU/IO module.
Important
•
See
Chapter 2 (5.1.2 Anti-static measures)
and
Chapter 2 (5.1.4 Preparing your
system for upgrade)
before starting installing or removing options.
•
To install or remove CPU or DIMM, first power off the server before removing the
CPU/IO module.
•
Removing the module being operating may cause unexpected trouble. Use the
management software (e.g., ft server utility or NEC ESMPRO Manager) to isolate
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 1 (6.1 Error Messages by LED Indication)
for details of the
Status LED.
•
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 can
result in interruption of the whole system.
