Configuring the Subrack Interconnect Board
The multi-reciter subrack interconnect board has a set of DIP switches and
links that must be set correctly before the equipment is used. The location
of these switches and links are shown in the diagram on the following page.
Switch Settings
You must ensure that switches S1, S2, S3 and S4 are set correctly for the
type of module installed in the equivalent subrack position. Only subrack
positions 3, 5, and 6 are affected. (Subrack positions 1, 2, 4 and 7 are for
reciters only and require no switch settings.) The following table gives the
switch settings for reciters, PAs, and for the PMU.
