Power Supply Connector Posts
The main and branch power supply connector posts are located on the rear panel
of the PDP, as illustrated in Figure 2-3.
Main power supply connector posts: Located on the right side of the PDP rear
panel, are used to connect the external power cables and input two channels
of DC -48V power into the PDP.
Branch power supply connector posts: Located on the left side of PDP rear
panel, are used to connect subrack power cables and output PDP’s power rail
to the subracks.
Caution:
P1 and P2 can be used together to provide redundant power rails for
each subrack, or used separately to provide a single non-redundant
power rail for each subrack.
If the equipment room provides only the single power rail, but the
AN5116-06B requires redundant power rails or 6 branch power rails,
users can use shorting plugs to short circuit -48V1 and -48V2; GND1
and GND2 of the main power supply connector posts.
