Installation, relocation, storage, and connection
Do not attempt to lift the server by yourself
Some server systems weigh 18 kg or more (R120f-1M: up to 21 kg, R120f-2M: up to 32 kg)
depending on the server components. Carrying the server by yourself may damage their back.
At least two persons should securely hold the server from its bottom when carrying it.
Do not install the server in other than the specified place.
Do not install the server in the following places or any place other than specified in 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 sodium 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 your
sales representative.
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.
Do not apply any weight on the server when it is pulled out from the rack
Do not apply force on the server when it is pulled out from the rack. Doing so causes 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/disconnecting any
interface cable to/from the server. If the server is off-powered but its power cord is plugged to a
power source, touching a cable or connector may cause an electric shock or a fire resulted from
a short circuit.
Use only the specified interface cable.
Use only interface cables provided by NEC and locate a proper device and connector before
connecting a cable. Using an unauthorized cable or connecting a cable to an improper
