Plug in to a proper power source.
Use a proper wall of specified voltage and current. Use of an improper power
source may cause a fire or a power leak.
Do not install the server switch unit where you need an extension cord. Use of a
cord that does not meet the power specifications of the server switch unit may heat
up the cord and cause a fire.
Do not connect the power cord to an outlet that has an illegal number of
connections.
The electric current exceeding the rated flow overheats the outlet, which may cause
a fire.
Do not connect the power cord to an outlet that has an illegal number of
onnections. c
The electric current exceeding the rated flow overheats the outlet, which may cause
a fire.
Plug the AC cord into the outlet as far as it goes.
Heat generation resulting from a halfway inserted AC cord (imperfect contact) may
cause a fire. Heat will also be generated if condensation is formed on dusty blades
of the halfway inserted plug, increasing the possibility of fire.
Use the authorized AC cord only.
Use only the proper AC cord that comes with the server switch unit. Use of an
unauthorized AC cord may cause a fire when the electric current exceeds the ra ted
flow. AC cord for Japan (100 VAC) is provided with the server switch unit. Do not
use the provided AC cord in any other country than Japan.
Also, observe the following to prevent an electric shock or fire caused by a
damaged AC cord.
n Do not stretch the cord harness.
n Do not pinch the power cord.
n Do not bend the power cord.
n Keep chemicals away from the AC cord.
n Do not twist the power cord.
n Do not place any object on the AC cord.
n Do not bundle power cords.
n Do not alter, modify, or repair the AC cord.
n Do not use any damaged power cord. (Replace a damaged AC cord with a new
one of the same specifications. Ask your service representative for replacement.)
Do not carry or install the rack only by a single person.
At least two persons are required to carry or install the rack. Failure to follow this
instruction may cause the rack to fall to result in personal injury and/or breakage of
surrounding devices. In particular, a high rack (such as 44U rack) is unstable if it is
not fixed by stabilizers. At least two persons must always carry or install the rack
while they support it.
Do not install the rack so that the load may be concentrated on a specific point.
Install stabilizers on the rack or earthquake-resistant construction to the rack so that
the total load of the rack and devices mounted on the rack is not concentrated on a
single point. Join the racks in multiple-rack installations to distribute the load.
Failure to follow this instruction may cause the rack to fall to result in personal
injury.
Do not install components on the rack only by yourself.
At least two persons are required to install parts including the doors and trays for
the rack. Failure to follow this instruction may cause some parts to fall to be broken
and/or to result in personal injury.
Do not leave more than one device being pulled out from the rack.
Pulling out more than one device from the rack may cause the rack to be fallen.
Only pull out a single device from the rack at a time.
Do not provide the wiring for the rack to exceed the rating of the power supply.
To prevent burns, fires, and device damages, the power supplied to the power
supply in the rack shall not exceed the rating load of the power branch circuit.
Contact the power constructor or local power company for the requirements on the
wiring and installation of electric facilities.

Installation, Relocation, Storage, and Connection
CAUTION
Do not install the server switch unit in any other place than specified.
Do not install the server switch unit in the following places or any other places than
specified in this User's Guide. Failure to follow this instruction may cause a fire.
n a dusty place
n a humid place such as near a boiler
n a place exposed to direct sunlight
n an unstable place
Do not connect any interface cable to the server switch unit with the server being
powered or the AC cord being connected.
Make sure to power off the server and unplug the AC cord from an outlet before
connecting/disconnecting the interface cable. If the server is off-powered but its AC
cord is plugged to a power source, touching the cable may cause an electric shock
or a fire resulted from a short circuit.
Do not use any unauthorized interface cable.
Use only interface cables specified by NEC and locate a proper device and
connector before connecting a cable. Using an unauthorized cable or connecting a
cable to an improper destination may cause a short circuit, resulting in a fire.
Also, observe the following notes on using and connecting an interface cable.
nDo not use any damaged cable connector. Before connecting an interface cable,
confirm that any cable connector is not damaged and any connector pin is not
bent or dirt.
n Do not step on the cable.
n Do not use the server switch unit with loose cable connections.
n Do not place any object on the cable.
n Do not disable the locking mechanism of the connectors.
Do not disassemble, repair, or alter the server switch unit.
Do not attempt to disassemble, repair, or alter the server switch unit. Failure to
follow this instruction may cause an electric shock or fire as well as malfunctions of
the unit.
Disconnect the AC cord before cleaning the server swit ch unit.
Make sure to power off the server and disconnect the AC cord from a power outlet
before cleaning. Touching any connectors with the server's power being on or with
the AC cord being connected to a power source may cause an electric shock or a
fire due to short circuit.
Also, disconnect the AC cord from the outlet occasionally and clean the plug with a
dry cloth. Heat will be generated if condensation is formed on a dusty plug, which
may cause a fire.
CAUTION
Make sure to complete cable and AC cord installations.
Always install the AC cord and an interface cable firmly. An incomplete installation
may cause a contact failure, resulting in smoking or fire.
During Operation
Do not touch the server switch unit when it thunders.
Disconnect the AC cord from the outlet when a thunderstorm is approaching. If it
starts thundering before you disconnect the AC cord, do not touch any part of the
server switch unit including cables. Failure to follow this warning may cause a fire or
an electric shock.
Do not use a cellular phone or pager around the server switch unit.
Turn off the cellular phone or pager around the server switch unit. Radio
interference may cause malfunctions of the server switch unit.
Keep any animal (pet) away from the server switch unit.
Pet's discharges or fur may enter the server switch unit and cause a fire or electric
shock.
The warning label is attached to components with possible danger or their vicinity in the server switch
unit to inform the user that a hazardous situation may arise when operating the unit (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 service representative.
Observe the following notes for successful operation of the server switch unit. Use of the server
switch unit ignoring the notes will cause malfunctions or failures of the unit.
n Make sure to power off the server switch unit and disconnect the AC cord from the power outlet
before connecting or disconnecting cables.
n Check to see that the Server Online lamp goes off and unplug the power cord from the outlet
before relocating the server switch unit.
n Clean the server switch unit on a regular basis (see Chapter 3). Regular cleaning proactively
prevents various failures of the unit.
n Lightning may cause a momentary voltage drop. To prevent this problem, it is recommended
to use an uninterruptible power supply.
n Use the keyboard and mouse which you purchased as components in the NEC Express5800
server system to connect them with the server switch unit. Using any other unauthorized
keyboard and mouse cause failures of the unit as well as a malfunction of the unit.
n Do not press two or more switches simultaneously. Doing so may cause a malfunction of the
unit.
n Use only the AC cord that comes with the server switch unit. Use of an unauthorized AC cord
may cause a failure of the unit or a fire when the voltage exceeding the rated one is applied to
the unit.
n Use NEC's genuine interface cables for options. Repair of the unit due to a failure or damage
resulted from use of a third-party product will be charged even in the warranty period.
