Maintenance 7-3
Startup and Exit of System Diagnostics
There are two ways to diagnose the CPU blade: to use the local console (keyboard) connected to the
Blade Enclosure, and to use the management PC via serial port (remote console).
IMPORTANT: Two methods of LAN and the serial port are mentioned
in "MAINTENANCE TOOLS" of Chapter 8 "Troubleshooting" in the
way of communicating in remote console.
Use the serial port to execute System Diagnostics with remote console.
The LAN connection is not for System Diagnostics.
Procedures to start the diagnostics program are as follows:
1.
Shutdown the OS, and turn off the CPU blade.
2.
Disconnect all the LAN cables from the Blade Enclosure. If the switch module is
connected with the Blade Enclosure, remove all the LAN cables from the switch module.
3.
Power on the CPU blade.
4.
Use the NEC EXPRESSBUILDER DVD to start the system.
5.
Select [Tool menu (Normal mode)] when local console of the CPU blade is used for, or
select [Tool menu (Redirection mode)] when remote console is used for.
NOTE:
If the system displays the [Language selection] menu, select
[English].
