4.2 Connecting External Rectifier

The external rectifier is an external power supply that provides the power to IP phones
connected to the OfficeServ 7200 when the PLIM, PLIM2, or GPLIMT board is used.
Since the capacity of the internal power is not sufficient for external equipment, additional
power supply is required.
The procedure to connect an external rectifier is as follows:
1) Switch off all powers for the OfficeServ 7200 and the external rectifier.
2) There are 3 screws to connect power cables to A and B (GND and -54 V) in the rear of
external rectifier. Prepare the power cables as shown in the figure below.
The power cables consists of a red line and a blue line and each end of the cables is
marked as GND (red cable) or -48 VDC (blue cable). The other ends are attached to
connectors to connect to the sockets of the external rectifier in the OfficeServ 7200.
3) Connect the power cables as shown in the figure below.
Connect GND (red cable) and 48 VDC (blue cable) of the power cables to A area
(GND) and B area (-54 V) separately. Any screw in an area can be available for the
connection.
