III.1.D. BACKPLANE OF POWER SUPPLIES WITH
BACKUP – BPL200-SPSX
Definition:
Two SPS248 power supply modules are connected to the BPL200-SPSX backplane. This
backplane is an alternative to the BPL200-SPS backplane. It is employed for backing up the
SPS248 power supply for each rack, in cases where the exchange is fed by an external
power supply.
The BPL200-SPSX cards in the main rack and in the auxiliary racks are almost the same
except a slight difference. The BPL200-SPSX backplane end of the cable, which provides
connection between the BPL200-SPSX backplane and BPL200-MAIN in the main rack, has
been fixed to the backplane. On the other hand, that end has not been fixed to the backplane
in the auxiliary rack; it is rather connected to the card by a connector.
The figure below shows the connectors on BPL200-SPSX and their explanations.

BPL200-SPSX has been mounted between the upper and lower back parts in the metal rack.
The connectors on BPL200-SPSX completely correspond to the module slots in order to
facilitate plugging of the SPS248 modules.
Dimensions of the BPL200-SPSX backplane are 12 cm x 9 cm and it weighs 0.1 kg.
