Handling precautions (for proper operations)
Be sure to observe the following precautions for the proper functioning of the server. Ignoring the precautions
may cause server malfunction or failure.
Do not use any cellphones and switch off them near the server. Electric waves from such devices can
cause server to malfunction.
Install the server in an appropriate place. For details about the installation location, see Chapter 2
Preparations (2. Installation and Connection).
Before connecting/removing cables to/from peripheral devices, make sure that the server is off and unplug
the power cord, if they are non plug-and-play devices.
Connect the provided power cord to a 100/200 VAC outlet.
Make sure that the access LED on the server is off before turning off the power or ejecting an optical disk.
Wait for at least 30 seconds before connecting power cord to power outlet after disconnecting it.
If any Uninterruptible Power Supply (UPS) unit is connected, set it to wait for at least 30 seconds before
turning on the server after power off.
Do not power off or reset the server, nor disconnect the power cord before POST completes.
Turn off the server and unplug the power cord before moving it.
Regularly clean the server to prevent various types of failure. See Chapter 1 Maintenance (2. Daily
Maintenance) in "Maintenance Guide" for details about cleaning.
Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is recommended.
In the following cases, check and adjust the system clock before operation.
‑ After transportation
‑ After storage
‑ After the server is used following a period of disuse, in which storage conditions did not conform to
those that guarantee server operations (temperature: 10 to 35°C; humidity: 8% to 90%).
Check the system clock approximately once per month. Use of a time server (NTP server) is
recommended if high accuracy timing is required by the system.
Observe the storage conditions (Temperature: -30°C to 60°C, Humidity: 5% to 95%, No condensation of
moisture) to store the server. If this server, internal optional devices, and media set for the backup devices
(tape cartridges) are moved from a cold place to a warm place in a short time, condensation will occur and
cause malfunctions and failures when these are used in such state. To protect important stored data and
property, make sure to wait for a sufficient period to use the server and components in the operating
environment.
Reference: Time effective at avoiding condensation in winter (more than 10°C differences between
the room temperature and atmospheric temperature)
Disk devices: Approximately 2 to 3 hours
Tape media: Approximately 1 day
This server does not support hibernation/standby function.
For optional devices, we recommend you use our NEC products. Even if they are successfully installed or
connected, installation of unsupported devices can cause the server to malfunction or even failure. You will
be charged to repair failure or damage caused by use of such products even within warranty period.

Using a computer extensively may affect different parts of your body. Here are tips you should follow while working on
a computer to minimize strain on your body.
Keep proper posture
The basic body position for using a computer is sitting straight with
your hands on the keyboard parallel with the floor, and your eyes
directed slightly downward toward the monitor. With the proper
posture described above, no unnecessary strain is applied on any
part of your body, in other words when your muscles are most
relaxed.
Working on the computer with bad posture such as hunching over or
being too close to the monitor could cause fatigue or deteriorated
eyesight.
Adjust the angle of your display
Most display units are designed for adjustment of the horizontal and
vertical angles. This adjustment is important to prevent the screen
from reflecting bright lights and to make the display contents easy to
see. Working without adjusting the display to a comfortable angle
makes it difficult for you to maintain a proper posture and you will
get tired easily. Adjust the viewing angle before use.
Adjust the brightness and contrast of the display
Display screens have functions to control brightness and contrast.
The most suitable brightness/contrast depends on age, individuals,
and environment, so adjust it to suit your preferences. A too bright or
too dark display is bad for your eyes.
Adjust the angle of keyboard
Some keyboards are ergonomically designed, which allow the angle
to be adjusted. Adjusting the angle of the keyboard is effective to
reduce tension on your shoulders, arms, and fingers.
Clean your equipment
Keeping your equipment clean is important not only for the appearance but also for functional and safety reasons. A
dusty monitor makes it difficult to see the display contents, so clean it regularly.
Take rest breaks
When you feel tired, take a break. Light exercise is also
recommended.
