Chapter 2 Preparations
Do not install the rack or server under the following environment. Doing so may cause malfunction of the
server.
•
Narrow space from which devices cannot be pulled out from the rack completely
•
Place that cannot bear the total weights of the rack and devices mounted on the rack
•
Place where stabilizers cannot be installed or where the rack can be installed only after the practice of
proper earthquake-resistant construction
•
Place of uneven or slanting floor
•
Place of drastic temperature change (near a heater, air conditioner, or refrigerator)
•
Place where intense vibration may be generated
•
Place where corrosive gases (sulfur dioxide, hydrogen sulfide, nitrogen dioxide, chlorine, ammonia,
ozone, etc) exist
Place where the air (or dust) includes components accelerating corrosion (ex. sulfur, sodium chloride)
or conductive metals
•
Place where chemicals may be accidentally sprayed over
•
Place where a carpet not subject to anti-static process is laid
•
Place where some objects may be fallen on the rack
•
Place near a device generating intense magnetic field (such as TVs, radios, broadcast/communication
antennas, power transmission wires, and electromagnetic cranes) is placed (If unavoidable, contact
your maintenance service company for proper shield construction.)
•
Place where the power cord of the server must be connected to an AC outlet that shares the outlet of
another device with large power consumption
•
Place near equipment that generates power noise (e.g., contact spark at power-on/power-off of
commercial power supply through a relay). If you must install the server close to such equipment, have
your maintenance service company separate power cables or install noise filter.
•
Environment where operation of the server is not guaranteed
