Using The System - NEC Express5800 320La User Manual

Using the System

The following subsections describe how to use this server system properly and
safely, including an explanation of the server system power on/off sequences,
what the POST program checks in the server, how to perform a forced power
shutdown, and how to reset the system.
When using the server system the following precautions should be observed.
Make sure you power off the server before connecting or disconnecting
!
cables between the server and peripheral devices. Connecting or
disconnecting the cables while the server is powered on may cause
malfunction or failures within the server.
Verify that the access lamp on the floppy disk drive is unlit before turning
!
off the server or ejecting the floppy disk. Turning off the server or
ejecting the floppy disk while the access lamp is lit may damage data
being stored on the floppy disk.
After turning off the server, wait at least 40 seconds before turning it on
!
again. Cycling the power immediately may cause malfunction or failures
of the server.
Before relocating the server unit, turn off the power and unplug the power
!
cords from the outlet. Moving the server unit when it is powered may
cause malfunction or failures of the server.
Some software includes a command to eject the CD-ROM tray. Make
!
sure that the front door (tower-based system) or front panel (rack-mount
system) of the server unit and the front door of the rack cabinet are
opened before running the command. Running this command with any
door or panel closed may cause the CD-ROM tray to hit against it,
resulting in a possible failure of the CD-ROM or power supply.
Clean the server regularly. Regular cleaning prevents failures of the
!
server and its components.
Lightning may cause a momentary voltage drop. To prevent this problem,
!
an optional uninterruptible power supply unit is recommended.
Only use options qualified by NEC for the server. An unqualified option
!
may be mounted or connected to the server, but it may fail to operate
normally or even cause failures. Note that damage resulting from
installation of unapproved devices is not covered under warranty.
