Safety notes
To use this server safely, read thoroughly the "Safety Precautions and Regulatory Notices" that comes with your
server. For symbols used in this document, refer to "Safety precautions".
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.
●General
– Do not block air vents of the CPU blades, Blade Enclosures, power supply units, and additional fan units.
– The CPU blade and internal option devices contain precision component that is easily affected by drastic
temperature change. If the device is used after storage or relocation, make sure that the device is fully
adapted to the operating environment.
– Do not touch the CPU blade terminals or on-board components by a bare hand nor place the CPU blade
directly on the desk.
– It is recommended to use options provided by NEC. Some memory devices and solid state drives of
other vendors are designed to be available for the server. If such an option causes the server to be
defected or damaged, you will be charged for the repair within the warranty period.
– Turn off the cellular phone or pager around the server. Radio interference may cause malfunctions of the
server.
●CPU blade
– N8400-230F/231F/232F/233F/234F/236F CPU blade should be installed in the Blade Enclosure
(SIGMABLADE).
– Install or remove CPU blades one by one.
– Hold the portions covered with metal plates when a CPU blade is installed or removed. To carry a CPU
blade, put it into the case in which the CPU blade was contained at the purchase and pack it into the
package.
– Check and adjust the system clock before the operation if any of the following conditions is applicable.
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C to 40C; humidity: 20% to 80%).
– Check the system clock at the rough rate of once per month. When the system clock is installed in a
system requiring high time precision, it is recommended to use a time server (NTP server).
If the system clock is remarkably delayed or advanced as the passage of time in spite of adjustment,
contact your sales representative to ask maintenance.
– Store the unit under the storage condition (temperature: –10°C to 55°C, humidity: 20% to 80%, without
condensation).
– Turn on the power of each CPU blade by pressing the POWER switch or the remote power-on operation
after the period of 60 seconds or longer has passed from the supply of power (the POWER LED of the
CPU blade goes on amber). The power of the CPU blade may not be turned on if the power-on operation
is done within the period of less than 60 seconds from the supply of power. After making sure that the
power is supplied to every CPU blade, turn on the power of each CPU blade by pressing the POWER
switch.

Precautions for Use (Be Sure to Read)
Express5800/B120f User's Guide
16
– After turning off the power of a CPU blade once, turn on the power again after 30 seconds have passed
from the power-off.
– Remove a CPU blade after turning off the power of the CPU blade.
– Do not perform any of the following operation during POST (including similar operations from EM card
and external applications).
Press the POWER switch of the CPU blade.
Press the RESET switch of the CPU blade.
Remove the CPU blade from the Blade Enclosure.
Disconnect the power cord from the power unit of the Blade Enclosure.
●Hard disk drive
– Confirm the slot to which the hard disk drive is inserted. The slot for the hard disk drive to be connected
to each CPU blade is defined previously.

Handling precautions (for Anti-static Measures)
This product contains static-sensitive electronic components. Follow this measures below to avoid a failure
caused by static electricity when installing or uninstalling any optional device.
●Wearing anti-static wrist strap or anti-static gloves
Wear a wrist strap on your wrist and connect the wire to the chassis. If there is no wrist strap, touch an
unpainted metal surface of the chassis connected to the ground to discharge static electricity from your body
before touching the component. Touch the metal part occasionally to discharge the static electricity while
working on the component.
●Checking the workplace
– Work on an anti-static floor or concrete floor.
– If you work on a place where static electricity is likely to be generated (e.g. carpet), be sure to provide
anti-static protection.
●Using the work table
Place the server on a mat with Electrostatic Discharge (ESD) protection.
●Clothing
– Do not wear wool or synthetic clothes.
– Wear anti-static shoes.
– Remove any kind of metal accessories such as a ring, bracelet or wrist watch.
●Handling of components
– Keep the component in an anti-static bag until you install it to the server.
– Hold the component by the edges to avoid touching any terminals or mounting parts.
– Place the component in an anti-static bag when storing or moving them.
●Handling of cables
When connecting a cable (e.g., LAN cable), static electricity may also be charged due to friction against the
floor.
Connecting the charged cable with an I/O device may cause damage to the devices in the system. It is
recommended to use a product such as electrostatic discharge kit to eliminate the static charge before
connecting the cable.
●Installing and uninstalling the optional device
– To avoid electric hazard and malfunction, be sure to turn off the power switch of the server and unplug
the power cord from the outlet before installing or uninstalling any optional device. If the device is
hot-swappable, you do not need to turn off the power switch and unplug the power cord.
– The device contains static-sensitive electronic components. When installing or uninstalling the optional
device, wear an anti-static wrist strap on your wrist to avoid a failure caused by the static electricity. To
use the strap, connect the wire to the chassis.

Express5800/B120f User's Guide 19
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.
