Do not install the rack in the places listed below. Not doing so may cause some
malfunctions to occur.
Do not:
● Locate the rack in a narrow space that would prevent devices from being pulled out from the rack
completely.
● Locate the rack on a floor that cannot bear the total weight of the rack and devices mounted in the
rack.
● Locate the rack in a place where stabilizers cannot be installed or where the rack can be installed
only after proper earthquake-resistant is constructed.
● Locate the rack on an uneven or slanting floor
● Locate the rack in an area with drastic temperature change (near a heater, air conditioner, or
refrigerator).
● Locate the rack where intense vibrations may be generated.
● Locate the rack where corrosive gas may be generated (sulfur dioxide, hydrogen sulfide, nitrogen
dioxide, chlorine, ammonia, ozone, etc), moreover where the ingredient which promotes corrosion,
conductive metal (sodium chloride, sulfur, etc.), etc. are contained in dust or air.
● Locate the rack in a place where some objects may fall on the rack.
● Locate the rack near a device that is generating intense magnetic fields (such as a TV, radio,
broadcast/communication antenna, power transmission wire, and electromagnetic crane.) If
unavoidable, contact your service representative to request proper shielding.)
● Locate the rack where the power cord of the server must be connected to an AC outlet that
shares other devices with large power consumption.
● Locate the rack next to an 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, request your service representative for separate power cabling or noise
filter installation.
