Do not install the rack in the places listed below. Installing the rack or mounting the server switch unit on the rack in such a place may cause some malfunction to occur.

￿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 gas is generated, chemicals are nearby, or 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 a TV, radio, broadcast/communication antenna, power transmission wire, and electromagnetic crane) is placed (If unavoidable, contact your service representative to request proper shield construction.)

￿Place where the AC cord of the server switch unit 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 switch unit close to such equipment, request your service representative for separate power cabling or noise filter installation.
