Note:
1. If an existing installation has a two cable configuration, we
recommend that you replace the cables with the newer cable
assembly.
2. You should use no more than two bus cables for the entire
subsystem.
Note:
The ACM/16 and ACM/16RJ require the connection of only
one external power supply for every 48 ports connected to a
HOST Adapter. Please connect the power supply to the POWER
IN connector on the first ACM/16 or ACM/16RJ module (16
ports) and then connect power cables between the POWER OUT
and the POWER IN connectors on the ACM/16 or ACM/16RJ
modules.
When you add another ACM/16 or ACM/16RJ module to bring
the total to 64 ports you must connect another external NT960
power supply to the POWER IN connector on this additional
ACM/16 orACM/16RJ module. If you add another 32 ports to
bring the total to 96 ports you can once again connect power
cables between the POWER OUT and POWER IN connectors on
the ACM/16 or ACM/16RJ modules. Please refer to Figures 11,
12 and 13 for connecting multiple ACM/16, ACM/16RJ or
ACM/Flex16 modules.
