
Important Refer to 5.1.3 Basics of Installation, Removal, and replacement in this Chapter
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 ftsmaint command to isolate the CPU module and I/O module to be
removed so that the CPU/IO 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.
