2.2.2 Combined/Redundant Amplifier Installation and Cabling
For the complete combined/redundant amplifier system, it is
most common to install the Mitec 2723B combiner in the top position
of the rack, followed by SSPA B, with SSPA A in the bottom position.
(See the outline drawing at the end of this section.)
Connect the Comtech supplied inter-unit control cable,
CA/8981, between the Mitec Combiner ports P1,P2,P3 and to each J5 of
SSPA A and SSPA B as indicated by the labels on the cable. (Note
that this cable is setup for the bottom SSPA be SSPA A.)
Attach the supplied waveguide termination to the load port of
the Mitec 2723B such that the termination resides above the unit.
