Starting and Ending the System Diagnostics

There are two ways to diagnose the server: to use the local console (keyboard) of the server itself, and to use the management PC via serial port (remote console).

Procedures to start the diagnostic program is as follows:

IMPORTANT: In the electronic "NEC EXPRESSBUILDER" User's Guide, you will find that both LAN and COM port can be used in remote console mode, however, in system diagnostics, only the COM port can be used.

1.Shutdown the OS, and turn off the server. Then, unplug the power cord.

2.Disconnect all the LAN cables from the server.

3.Plug the power cord and turn on the server.

4.Use the EXPRESSBUILDER CD-ROM to reboot the server.

See the electronic "NEC EXPRESSBUILDER" User's Guide for details.

The following menu appears when started the server using the EXPRESSBUILDER.

Local console

Remote console

5.Select [Tools].

6.Select [System Diagnostics].

The system diagnostics starts and completes in approximately three minutes.

When the diagnosis completes, the following appears on the screen of the display unit.
