3-4 Setting Up Your Server
Before you begin the rack installation review the following guidelines.
Do Not:
„
Locate a rack in a narrow space that would inhibit 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 that has drastic temperature change (near a heater, air
conditioner, or refrigerator).
„
Locate the rack where intense vibration may be generated.
„
Locate the rack where corrosive gases (sulfur dioxide, hydrogen sulfide, nitrogen dioxide,
chlorine, ammonia, ozone, etc) exist.
And also, locate it in the environment where the air (or dust) includes components
accelerating corrosion (ex. sulfur, sodium chloride) or conductive metals.
„
Place the rack on a carpet not subject to the anti-static process.
„
Locate the rack 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 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.
„
Locate the rack where following conditions can not be satisfied.
Conditions for operation: *
Temperature: 10 to 35
°
C
Humidity: 20 to 80% (no condensation)
* It is recommended that the server should be used in a room where temperature is in the
range between 15 to 25
°
C.
