•
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

antennas, power transmission wires, and electromagnetic cranes) is placed.
•
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
