Model 117A4 Carrier Installation Instructions Installing Multiple Carriers
Model 117A4 Carrier Installation Instructions
503-801-18034 Issue 2 February 1999
Installation Self Test with a Single Radio Module in Each Carrier
1
Wait a few seconds after powering the carriers, then verify that the carriers’ OUT
OF SYNC LEDs are not lit.
2
The following illustration shows the correct LED lights for a five-carrier
installation with one radio module installed in each carrier. This example
installation has four 117A4 carriers—one acting as the control carrier and the
other three acting as expansion carriers—and one 117A3 carrier acting as an
expansion carrier.
When the correct installation procedures are followed and one radio module is
present in each carrier, the red OUT OF SYNC LEDs will not be lit on any
carrier, no matter which model. The other LEDs will be lit as follows:
~
Model 117A4 control carrier CONTROL/EXPANSION LED = Green
~
Three Model 117A4 expansion carriers CONTROL/EXPANSION LED =
Amber
~
The radio modules’ PASS and POWER LEDs = Green
The Model 117A3 expansion carrier has no CONTROL/EXPANSION LED,
but the DIP switch in Slot 4 of the carrier is set to Expansion.
