Installation, Relocation, Storage, And Connection - NEC express5800 A2010b User Manual

Installation, relocation, storage, and connection

Do not attempt to lift the server by three or less persons
Some servers weigh up to 55 kg depending on the server components. Carrying the server by three or
less persons may damage their back. At least four persons should securely hold the server from its
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 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 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.
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/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 authorized 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.
• Do not use any damaged cable connector.
• Do not step on the cable.
• Do not place any object on the cable.
• Do not use the server with loose cable connections.
• Do not use any damaged cable.
