Usage of System Diagnostics
After turning off the server or restarting the server, run System Diagnostics in the following procedure.
1. System Diagnositics is done by using,EXPRESSBUILDER, which is attached to main machine.
If it is not necessary to diagnose hard disk drives for System Diagnostics, remove all the hard disk drives
installed to main machine.
If it is necessary to diagnose a hard disk drive, install the hard disk drive to primary CPU/IO module only.
Remove a hard disk drive of secondary CPU/IO module from main machine.
Important If EXPRESSBUILDER is to be started on main machine, remove hard disk
drives from both primary and secondary CPU/IO modules. Or, install a hard
disk drive to primary CPU/IO module only. Do not start EXPRESSBUILDER
while hard disk drives are installed to both
primary and secondary CPU/IO
modules.
Note
For primary CPU/IO module, check the PRIMARY lamp on the front side of
CPU/IO module (Refer to
Chapter 1 (6.1 Error Indication by LED)

Since removed hard disk drives go back to the original locations after System
Diagnostics are completed, make a note which one goes where beforehand.
