III.2.B. BACKPLANE OF THE POWER SUPPLY–
BPL200S-SPS
Definition:
The power supply module of the exchange is connected to the Power Supply backplane.
The Power Supply backplane has been mounted between the upper and lower back parts in
the metal rack. The connector on the backplane fully corresponds to the module slot in order
to facilitate plugging of the power supply module.
Dimensions of the BPL200S-SPS backplane are 11.5 cm x 4.5 cm and it weighs 0.1 kg.
III.2.B.1. HR08 POWER FAILURE TRANSFER STATION
RELAY MODULE CONNECTOR
If the batteries exhaust due to prolonged power failures that affect the DS200S exchange,
then the connection of the exchange with the outer world may completely cease. In order to
prevent such a case, the HR08 module can be installed, so that desired extensions are
transferred to desired lines in the event that the DS200S exchange has become completely
off line.
The HR08 connector on the BPL200S-SPS backplane is used to put HR08 into operation
when the exchange battery gets into the low current cut-off mode (i.e., when the exchange
has been shut down).
Pinouts for the HR08 connector are as in the table below:
Pin no Signal
1 Shut
2 -48VDC
