Intended Application Uses
This product was evaluated as Information Technology Equipment (ITE), which may be installed in offices,
schools, computer rooms, and similar commercial type locations. The suitability of this product for other product
categories and environments (such as medical, industrial, residential, alarm systems, and test equipment), other
than an ITE application, may require further evaluation.
Site Selection
The system is designed to operate in a typical office environment. Choose a site that is:
 Clean, dry, and free of airborne particles (other than normal room dust).
 Well-ventilated and away from sources of heat including direct sunlight and radiators.
 Away from sources of vibration or physical shock.
 Isolated from strong electromagnetic fields produced by electrical devices.
 In regions that are susceptible to electrical storms, we recommend you plug your system into a surge
suppressor and disconnect telecommunication lines to your modem during an electrical storm.
 Provided with a properly grounded wall outlet.
 Provided with sufficient space to access the power supply cord(s), because they serve as the product's main
power disconnect.
 Provided with either two independent AC power sources or two independent phases from a s single source.
See “Power and Electrical Warnings” on page 174.
