Safety Notices
Caution:
Lithium batteries can be dangerous. Improper handling of lithium
batteries may result in an explosion. Dispose of lithium batteries as
required by local ordinance. Replace only with the same or equivalent
type battery.
The equipment uses 3-wire, grounded power cords. To prevent
electrical hazards, do not remove or defeat the ground prong on the
power cords. Replace a power cord if it gets damaged. The detachable
power supply are intended to serve as the disconnect devices. Contact
your dealer for an exact replacement.
The DC push-button on/off switch on the front panel does not turn off
the system AC power. Also, +5vdc is present on the system board
whenever the AC power cords are connected between the system and
an AC outlet. Before doing the procedures in this manual, make sure
that your system is powered off and unplug the AC power cords from
the back of the chassis. Failure to disconnect power before opening
your system can result in personal injury and equipment damage.
Under no circumstances should the user attempt to disassemble the
power supply. The power supply has no user-replaceable parts. Inside
the power supply are hazardous voltages that can cause serious
personal injury. A defective power supply must be returned to your
dealer.
Never connect the ground wire to a gas pipe. There is a risk of a gas
explosion.
Immediately after powering off the system, components such as CPU
processor heatsinks and hard disk drives may be very hot. Wait for the
system to cool down completely before adding / removing components.
Do not attempt to remove a device while it is in operation. Device
malfunction or personal injury may result.
Be careful not to get your fingers or hair caught in cooling fans located
in the back of a running server.

Using This Guide ix
■Be sure to power off the equipment and unplug its power cords from the wall outlet
before installation/relocation. All voltage is removed only when the power cords
are unplugged.
■Turn off your cellular phone or pager when you use the equipment. Their radio
waves may cause the equipment to malfunction.
■Do not use damaged power cords. Replace it with a new one of the same type.
■In the U.S.A. and Canada, the power cord must be a UL-listed detachable power
cord (in Canada, CSA-certified), type ST or SJT, 16 AWG, 3-conductor, provided
with a molded-on NEMA type 5-15 P plug cap at one end and a molded-on cord
connector body at the other end. The cord length must not exceed 9 feet (2.7
meters).
■Outside the U.S.A. and Canada, the plug must be rated for 250 VAC, 10 amp
minimum, and must display an international agency approval marking. The cord
must be suitable for use in the end-user country. Consult your dealer or the local
electrical authorities if you are unsure of the type of power cord to use in your
country. The voltage change occurs via a switch in the power supply.

Warning: Safety Notices for Users Outside of the
USA and Canada
■PELV (Protectec Extra-Low Voltage) Integrity: To ensure the extra-low
voltage integrity of the equipment, connect only equipment with mains-protected
electrically-compatible circuits to the external ports.
■Remote Earths: To prevent electrical shock, connect all local (individual office)
computers and computer support equipment to the same electrical circuit of the
building wiring. If you are unsure, check the building wiring to avoid remote earth
conditions.
■Earth Bonding: For safe operation, only connect the equipment to a building
supply that is in accordance with current wiring regulations in your country. In the
U.K., those regulations are IEE.

Fire Related Notices
Caution:
To prevent fires, and damage to the equipment and supply wiring,
make sure that the rated load of the power branch circuit is not
exceeded. Equipment nameplate ratings should be used when
addressing this concern. For more information on installation and wiring
of power-related facilities, contact your electrician or local power
company.
If the equipment emits smoke, odor, or noise, immediately turn off the
POWER switch, unplug the cord, and contact your sales agent. There
may be a risk of a fire.
Use a wall outlet with the specified voltage rating and power type.
Otherwise, there is a risk of fire or current leakage.
Avoid installing the equipment where you may need an extension cord.
If you use a cord that does not meet power specifications, there is a risk
of overheating that could lead to a fire.
Insert the plug firmly into an outlet. Otherwise, there is a risk of heat or
fire due to a poor contact. If dust settles on the slots and it absorbs
moisture, there is also a risk of heat or fire.
Use only the supplied power cords. If the rated current of the power
cord is exceeded, there is a risk of fire. Also observe the following
prohibitions to prevent damages to cords:
Do not pull on the cord.
Do not pinch the cord.
Do not bend the cord.
Keep chemicals away from the cord.
Do not twist the cord.
Do not place any object on the cord.
Do not bundle several cords.
Do not alter, modify, or repair the cord.
Do not staple the cord.
Use only interface cables designed for your server. Identify which
component or connector to attach beforehand. If you use a wrong cable
or make a wrong connection, there is a risk of short-circuit that could
lead to a fire. You also have to observe the following prohibitions about
handling and connecting interface cables:
Do not use any damaged cable connector.
Do not step on the cables.
Disconnect the power plug 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 fire.
Firmly install all power cords interface cables and/or boards. An
incompletely installed component may cause a contact failure, resulting
in smoke and/or fire.

Shock Related Notices
WARNING
Do not insert a wire or metal objects into a vent or disk drive slot. There
is a risk of an electric shock.
Do not let water or foreign objects (e.g., pins or paper clips) enter the
equipment. There is a risk of a fire, electric shock, and breakdown.
When such objects accidentally enter the equipment, immediately turn
off the power and unplug the cord. Contact your sales agent instead of
trying to disassemble it yourself.
Do not plug/unplug a power cord with wet hands. There is a risk of an
electric shock.
Make sure to power off the server and unplug the power cord from a
power outlet before installing/removing any optional internal device or
connecting/disconnecting any interface cable to/from the server. If the
server is powered off, but its power cord is plugged to a power source,
touching an internal device, cable, or connector may cause an electric
shock or a fire.
Unless described herein, never attempt to disassemble, repair, or alter
the equipment. There is a risk of an electric shock or fire as well as
malfunction.
You may want to unplug the equipment if a thunderstorm is eminent. Do
NOT touch the equipment and cables during a thunderstorm in your
area. There is a risk of a fire or electric shock.
Make sure to power off the server and disconnect the power plug from
a power outlet before cleaning or installing/removing internal optional
devices. Touching any internal device of the server with its power cord
connected to a power source may cause an electric shock even if the
server is off.
