Do not install the rack in the places listed below. Installing the rack or mounting the server on the rack in such a place may
cause some malfunction to occur.
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 gas is generated (ex. the area, where the vapour of sulphur is generated), chemicals
are nearby, or chemicals may be sprayed accidentally.
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.
* If installed in a closed or multi-unit rack assembly, required air flow for cooling might not be maintained, and this
cause the operating ambient temperature of the rack environment may rise greater than room ambient. Therefore,
consideration should be given to installing the server in an environment compatible with the rated ambient
temperature (10 to 35°C) and appropriate air flow.
