Baseband connections between CT and Expansion Racks
Inter-rack Baseband connections to Expansion Rack
Remove the blank panel located immediately below the combiner shelf on the CT Rack
Run a Baseband ribbon cable from each modem shelf in the Expansion Rack to the combiner
shelf via the hole created by the removal of the breakout sections during the rack installation.
Insert the connector into the Baseband socket on the Modem Interface shelf (see) and into
the appropriate socket on the Combiner Shelf backplane (the sockets are located behind the
switches). If using a Hybrid Rack these connections will differ from the illustration below. (see
Hybrid Rack Modification for Directional Antenna)
Combiner Shelf Ribbon Connections
Run the alarm bus ribbon from the Alarm and Breaker panel to the Alarm Bus socket in the
CT Rack wiring loom.
