Input Power
For backup purposes, ShoreTel recommends that all ShoreGear voice switches and the
ShoreWare server be connected to an uninterruptable power supply (UPS). This
ensures that telephone service will continue in the event of a power interruption.
Table 13-2 shows the power requirements for the ShoreGear voice switches.
Power and Heat Dissipation
The voice switches dissipate power and heat. ShoreTel recommends that you use the
information provided in Table 13-3 to help calculate the ventilation requirements of the
equipment room.
Environmental Requirements
The ShoreGear voice switches require that the environmental specifications provided in
Table 13-4 be met.
