Cpu Module - NEC Express 5800 User Manual

CPU MODULE

Concerning the CPU module, you can add or replace the following components, or CRU
(customer-replaceable units):
CPU (processor)
DIMM (memory)
Remove the CPU module to install or remove these devices. The figures used in this section show
the rack-mount model. The orientation is the only difference from the tower model.
IMPORTANT:
Ask your sales agent to replace the CPU module and components of the CPU module.
Make sure to read "Anti-static Measures" and "Preparing Your System for Upgrade" before
installing or removing options.
To install or remove CPU or DIMM, first power off the server before removing the CPU module.
The procedures described below are for replacement of DIMMs.
Removing the module being operating may cause unexpected trouble. Use the management
software (e.g., ft server 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 module. For
information on the status LEDs, see "LEDs" in Chapter 2.
Handle the module fixing screw with your hand, not by using any tool.
If you have replaced the module, attach an HDD ID label indicating the replaced module
number to the upper part of the fixing screw of the module.
When replacing a PCI module and a CPU module, replace one module and wait until dual
configuration is established to replace the other module. If you replace the both modules
simultaneously, dual configuration of either CPU modules or PCI modules may fail. (See
Chapter 7 "Troubleshooting.")
