Keep this user’s guide at hand for quick reference at any time it may be required.
Read “SAFETY INDICATIONS” first, and then proceed to “NOTES ON USING THE NEC

EXPRESS SERVER

”.

SAFETY INDICATIONS

To ensure proper and safe use of the server, handle the server according to the direction
of the Maintenance Guide.

The Maintenance Guide describes possible dangers in use of the server, the dangers you
encounter if you do not observe the instructions, and the ways to avoid the dangers.

Warning labels are attached to components with possible danger or their vicinity in the
server when operating the server.

In the Maintenance Guide and the warning labels, "WARNING" and "CAUTION" are
used as the terms indicating hazardous levels. The terms are defined to have the
following meanings.

WARNING

Indicates the presence of a hazard that may cause loss of
life or serious personal injury if the instruction is ignored.

CAUTION

Indicates the presence of a hazard that may cause minor
personal injury, including the burn, or property damage if the
instruction is ignored.

Precautions and notices against hazards are presented with one of the following 3
symbols. The individual symbols are defined as follows:

This symbol indicates the presence of a hazard if the instruction is
ignored. An image in the symbol illustrates the hazard type.
(Attention)

This symbol indicates prohibited actions. An image in the symbol
illustrates a particular prohibited action. (Prohibited Action)

This symbol indicates mandatory actions. An image in the symbol
illustrates a mandatory action to avoid a particular hazard.
(Mandatory Action)

( Example)

Symbol to draw attention
Term indicating a degree of danger

CAUTION

Do not touch components in the NEC Express server
while they are hot.

Components (e.g., especially hard disk drive) in the
server are hot immediately after the power is turned off.
Mount/dismount components only when th y are cool. e

CHAPTER 1

NOTES ON USING YOUR SERVER

This chapter includes information necessary for proper and safe operation of the NEC Express
server.

About Warning Labels

The warning label is attached to components with possible danger or their vicinity in the NEC
Express server to inform the user that a hazardous situation may arise when operating the server.
(Do not take off any label or soil it.)

If you find any label unattached, almost peeled off, or soiled, making the warning illegible, contact
your sales agent.

It is
stuck on
the
inside o

cover.

Safety Notes

This section provides notes on using the NEC Express server safely. Read this section carefully
to ensure proper and safe use of the server. For symbols, see "SAFETY INDICATIONS"
provided earlier.

For Proper Operation

Observe the following notes for successful operation of the server. Use of the server ignoring the
notes will cause malfunctions or failures of the server.

 Install the server in a place that meets requirements for successful operation. For details,

see Chapter 3, "Setting Up Your Server."

 Make sure to power off the server before connecting or disconnecting cables between the

server and peripheral devices.

 Verify that the access lamp on the server is unlit before turning off the server or ejecting

the floppy disk.

 When plugging the power cord to the system, you may experience 10 seconds delay from

the time you press the POWER switch on the front panel. This is normal system
operation.

 When you have just turned off the server, wait at least 30 seconds before turning it back

on.

 Do not turn off the server until characters appear on the screen.

 For the disk which does not conform to the CD standard, the playback of such a disk with

the CD drive is not guaranteed.

 Turn off the power and unplug the power cord from the outlet before relocating the

server.

 Clean the server on a regular basis. (See Chapter 7 for cleaning.) Regular cleaning

proactively prevents various failures of the server.

 Lightning may cause a momentary voltage drop. To prevent this problem, it is

recommended to use of an uninterruptible power supply unit.

 Make sure to use optional devices supported by the server. Some non-supported devices

may be physically installed/connected but cause failures of the server as well as
malfunctions of the server.

 NEC recommends you use NEC's genuine products. Some third-party products claim

that they support the server. However, repair of the server due to a failure or damage
resulted from use of such third-party products will be charged.

9

Transfer To A Third Party

The following must be observed when you transfer (or sell) the server or software provided with
the server to a third party:

Make sure to provide the manual along with the server to a third party.

IMPORTANT: It is the user's responsibility to completely
erase or modify all the data stored in storage device such as
hard disk so that the data cannot be restored.

Provided software

To transfer or sell any software application that comes with the server to a third party, the
following requirements must be satisfied:

 All provided software applications must be transferred and no backup copies must be

retained.

 Transfer requirements listed in "Software License Agreement" that comes with each

software application must be satisfied.

 Software applications that are not approved for transfer must be uninstalled before

transferring the server.

10

DISPOSAL AND CONSUMABLES

 Dispose the server, all the internal devices, floppy disks, and CD-ROMs according to all

national laws and regulations.

IMPORTANT:

♦ ♦ For disposal (or replacement) of the battery on the mother board of

the server, consult with your sales agent.

It is the user's responsibility to completely erase or modify all the
data stored in storage device such as hard disk so that the data cannot
be restored.

 Your server contains some components that are only good for a limited period of time and

require replacement, such as fans, internal batteries, the internal CD-ROM drive, the
floppy disk drive, and the mouse. For stable operation of the server, NEC recommends
you replace these components on a regular basis. Consult with your sales agent for
replacement or the product lives.

11

12

USER SUPPORT

Before Asking for Repair, do the following when the NEC Express server appears to fail:

1. Check if the power cord and the cables to other devices are properly connected.

2. See Chapter 6 to find if your problem fits the description. If it does, take the

recommended measure for it.

3. Check if the software required for operation of the NEC Express server is properly

installed.

If the NEC Express server still appears to fail after you have taken the above actions, consult with
your sales agent immediately. Take notes on lamp indications of the server and alarm indications
on the display unit before consultation, which may provide a significant help to your sale agent.
