Power Requirements
Phantom or Auxiliary Power
The 8503T voice terminal can receive power from the switch or from an auxiliary
power supply. The installer can select the type of power used by setting two
jumpers on the bottom of the voice terminal under a sliding plate between the Line
jack and the Adjunct jack. A pictorial representation of the jumpers is located to
the right of the sliding plate. These jumpers are labeled PHAN (phantom power)
and AUX (auxiliary power). The voice terminal is shipped in the PHAN position.
You must verify that the jumper settings are set correctly for your configuration.
NOTE:
The power jumpers must be setonlyby qualified service personnel.
nPHAN (phantom power) should be selected when power is provided by the
PBX. When the jumpers are set to PHAN, less than one Watt of power will
be drawn from the switch to suppor t normal operation.
nAUX (auxiliary power) should be selected when power is provided in the
closet. When the jumpers are set to AUX, the 8503T voice terminal will
operate on a nominal 40 or 48 Vdc, UL-listed Communications Circuit
Power source.
