PPS and RPS alarm signals are passed via a wire cable from the RPS power supply
slot on the motherboard to the PBD-ATS card that services the Peripheral Shelf Unit
in which the PPS and optional RPS Power reside.
The alarm cabling is connected on the backplane of the even numbered peripheral
shelves as follows: (P3 is located behind the PPS and RPS power supply slots, on the
backplane of the motherboard.)
When the Peripheral Shelf Unit does not include an odd shelf:
P6 on the PBD-ATS is connected to Pin 29 of P3 on the even shelf.
When the Peripheral Unit includes an odd shelf:
P6 on the PBD-ATS is connected to Pin 29 of P3 on the even shelf.
P7 on the PBD-ATS is connected to Pin 27 of P3 on the even odd shelf.
An FC1 cable is connected between pins 1-7, denoted
To Lower MBS3
, on
P3 of the odd shelf to pins 19-25, denoted
To Upper MBS3
, on P3 of the
even shelf.
H-41 connector (2-wire) cables are used to connect between P6/P7 and P3.
The three pin connector can be attached to the upper 3 pins or lower 3 pins of P6/P7,
so that if one of the pins break, there is always an alternative wiring option.
The H41 cable orientation is significant. Verify that the white colored wire is
connected between the lowest of the three pins in P6/P7 to the right pin of
Pin 27 / Pin 29.
illustrates the location of RPS inter-shelf cable FC1 and PPS/RPS Alarm
cable H-41 with polarity. The FC1 carries the RPS control signals and outputs between
the odd and even peripheral shelves. The H-41 cable carries alarm signals to the
PBD-ATS servicing the Peripheral Unit which contains the PPS (and RPS).
The appearance of some flat cables may vary from the illustration, and the conductors
may exit from the right side of the connector instead of the left as shown. Note the
position of the white dot which appears on the connectors of most FC1 cable
assemblies. If the white dots are not visible on the cable assembly, make certain that
the color of the wire conductor at the top edge of the cable is the same at both ends.
