Your server is not intended to be used with or control facilities or devices

concerning human lives, including medical devices, nuclear facilities

and devices, aeronautics and space devices, transportation facilities

and devices; and facilities and devices requiring high reliability. NEC

assumes no liability for any accident resulting in personal injury, death,

or property damage if the server has been used in the above conditions.

Do not use the server if any smoke, odor, or noise is present.

If smoke, odor, or noise is present, immediately turn off the power and

disconnect the power plug from the outlet, then contact your sales

agent. Using the server in such conditions may cause a fire.

Keep needles or metal objects away from the server.

Do not insert needles or metal objects into ventilation holes in the server

or openings in the floppy disk or CD-ROM drive. Doing so may cause

an electric shock.

Do not use the server in any unapproved place.

Install the server on a standard EIA 19-inch rack assembly. Do not

install the rack containing the server in a place inappropriate to the rack

installation environment.

Failure to follow these instructions may cause some bad influences to

be imposed on the server and other systems installed on the rack and

also a fire or personal injury due to falling of the rack may occur. For

the detailed explanation on the place where the server should be

installed and the earthquake-resistant construction for the rack, refer to

the manual attached to the rack or contact you sales agent.

Always install the server on a rack conforming to the relevant standard.

Install the server on a rack conforming to the EIA standard for the server

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 proper wall outlet. Use of an improper power source may cause

a fire or a power leak.

cord that does not meet the power specifications of the server may heat

p the cord and cause a fire.u

ay cause a fire.m

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

ossibility of fire.p

Use the authorized power cord only.

Use only the power cord that comes with the server. Use of an

unauthorized power cord may cause a fire when the electric current

exceeds the rated flow.

Also, observe the following to prevent an electric shock or fire caused by
