Using The System - NEC EXPRESS5800/120Md Series 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, and how to perform a forced
power shutdown.
When using the server system the following precautions should be observed.
Do not delete the hard disk partition exclusively provided for
!
maintenance of the server although it may appear on the operating system
(OS). Deleting the hard disk partition may cause malfunction of the
server.
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 server 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, turn off the power and unplug the power
!
cord from the outlet. Moving the server when it is powered may cause
malfunction or failures of the server.
Some software includes a command to eject the CD-ROM tray or a media
!
in a device mounted in the 5.25-inch device bay. Make sure that the front
door of the tower-based cabinet is open before running the command.
Running this command with the front door closed may cause the CD-
ROM tray or the media to hit against the front door, resulting in a
possible failure of the CD-ROM.
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 uninterruptible power supply unit is recommended.
Only use options recommended for the server. A non-recommended
!
option may be mounted or connected to the server, but it may fail to
operate normally or even cause failures.
