CPU/IO Module
To replace a processor (CPU), memory (DIMM), and PCI card, remove the CPU/IO module.
Important
See
Chapter 2 (5.1.3 Precautions for installing/replacing optional
devices
)
and
Chapter 1(1.8 Anti-static Measures) in Safety Precautions and Regulatory
Notices
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 CPU/IO module being operating may cause unexpected trouble.
Use the management software (e.g., ft server utility or NEC ESMPRO Manager) to
isolate the CPU/IO module to be removed so that the CPU/IO module is removed
when it is stopped, without fail.
Then remove the relevant CPU/IO module after verifying the Status LED on the
CPU/IO module. See
Chapter 1 (6.1 Error Indication by LED)
for details of the
Status LED.
When replacing both CPU/IO modules, replace one CPU/IO module and wait until
dual configuration is established to replace the other CPU/IO module. If you
replace the both CPU/IO modules simultaneously, establishing dual CPU/IO
module configuration can result in interruption of the whole system.
