Rack installation
CAUTION
Do not attempt to carry or install the server alone
More than t
wo people are required to carry or install the rack. Otherwise, the rack may fall, resulting in
personal injury or damage to peripheral devices. In particular, tall racks such as a 44U rack become
unstable unless steadied with a stabilizer. Make sure that
two or more people hold the rack to carry or
install the rack.
Do not install with the load weight distributed unevenly
To avoid unevenly distributing the load of the rack and server, install a stabilizer or connect multiple racks
to distribute the weight. Otherwise, the rack may fall, resulting in personal injury.
Do not install components alone, and check the door hinge pins of the rack
Two or more people are required to install the rack components such as the door or rails. When installing
the door, make sure that both upper and lower hinge pins are held in place. Incomplete attachment may
cause components to fall off as well as personal injury.
Do not extend any device from the rack that is not stabilized
When extending a device from the rack, make sure that the rack is stable (by using a stabilizer or seismic
reinforcement). Otherwise, the rack may fall, resulting in personal injury.
Do not extend more than one device out of the rack
Extending multiple devices from the rack may cause the rack to fall, resulting in personal injury. Extend
only one device at one time.
Do not exceed the rated capacity of the power supply when connecting devices
To prevent burn injuries, fire, and damage to the server, make sure the loa
d on the branch circuit that
supplies power to the rack will not exceed the rated load. For inquiries regarding the installation or wiring
of the power supply system, consult with the company that performed the installation or wiring, or the
power company that services your area.

Power supply and power cord use
WARNING
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this warning may cause an
electric shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. Failure to follow this warning may cause a gas explosion.
CAUTION
Plug in to a proper power source.
Use a gro
unded outlet with the specified voltage. Use of an outlet with a voltage other than that specified
causes fire and electrical leakage. Do not install the server in any environment that requires an extension
cord. Connecting to a cord that does not conform
to the power supply specs of the server causes
overheating, resulting in fire.
If you want to use an AC cord set with a ground wire of class 0I, be sure to connect the ground wire
before inserting the power plug into the outlet. Before disconnecting the gr
ound wire, be sure to
disconnect the power plug from the output.
Do not connect many cords into a single outlet by using extension cords.
The electric current exceeding the rated flow overheats the outlet, which may cause a fire.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (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.
Do not use any unauthorized interface cable.
Use only the interface cables provided with the server. Electric current that exceeds the amount allowed
could cause fire. Also, observe the following precautions to preven
t electrical shock or fire caused by a
damaged power cord.
•Do not stretch the cord harness
•Do not bend the power cord.
•Do not twist the power cord
•Do not step on the power cord.
•Uncoil the power cord before use
•Do not secure the power cord with staples or
equivalents
•Do not pinch the power cord
•Keep chemicals away from the power cord
•Do not place any object on the power cord
•Do not alter, modify, or repair the power cord
•Do not use a damaged power cord (replace the
damaged power cord with a power cord of the
same standard. For information on replacing
the power cord, contact the store where you
purchased the product or a maintenance
service company)

License Notification
Express5800/E120e-M User's Guide
19
CAUTION
Do not use the attached power cord for any other devices or usage.
The power cord that comes with your server is designed aiming to connect with this server
and to use
with the server, and its safety has been tested.
Do not use the attached power cord for any other
purpose. Doing so may cause a fire or an electric shock.
Do not pull out a cable by gripping the cable part.
Pull a cable straight out by gripping the connector part. Pulling a cable by gripping the cable part or
applying extra pressure to the connector part may damage the cable part, which may c
ause a fire or
electric shock.
Installation, relocation, storage, and connection
CAUTION
Do not attempt to lift the server by two or less persons
Some servers weigh up to 41 kg depending on the server components. Carrying th
e server by yourself
may damage your back. At least three
people should securely hold the server from the bottom when
carrying it. Do not attempt to lift the server while the front bezel attached.
Doing so causes the front bezel
to fall off the server, resulting in personal injury.
Do not install the server in any place other than specified.
Do not install the server in the following places or any place other than specified in this User'
s Guide.
Failure to follow this instruction may cause a fire.
•A dusty place
•A humid place such as near a boiler
•A place exposed to direct sunlight
•An unstable place
Do not use the server in an environment where corrosive gas is present
Do not install the server in a place subject to corrosive gases including s
odium chloride, sulfur dioxide,
hydrogen sulfide, nitrogen dioxide, chlorine, ammonia, or ozone.
Do not install the server in an
environment that contains dust, chemicals that accelerate corrosion such as NaCl or sulfur, or conductive
materials. Failure to follow this warning may cause the wiring on the printed wiring board to short-
circuit,
leading to fire. If you have any questions, contact the store where you purchased the product or a
maintenance service company.
Do not install the server while the cover is removed
Do not install the server to a rack while the cover or other relevant items removed.
Not only will the
cooling effect within the server decrease, causing the server to malfunction, but also may allow dust to
enter the server, resulting in fire or electrical shock.
Do not get your fingers caught in the rails
When mounting/removing the server onto/from the rack, be careful to avoid getting your fingers caught in
the rails or cutting your fingers on the rails.

License Notification
Express5800/E120e-M User's Guide
20
CAUTION
Do not apply any weight on the server when it is extended from the rack
Do not apply force on the server when it is extended from the rack. Doing so cause the frames to bend,
which makes it impossible to be mounted on the rack. It also
may cause the server to fall, resulting in
personal injury.
Do not attempt to connect or disconnect the interface cable while the power cord is plugged into
an outlet
Be sure to unplug the power cord from a power outlet before connecting/disconnec
ting any interface
cable to/from the server. If the server is off-
