1.0 ABOUT THIS MANUAL
This guide describes:
• Installation planning for a P20 Redundant Transceiver Chassis
• Instructions for installing transceivers in a Redundant Trans-
ceiver Chassis
• Instructions for installing a Redundant Transceiver Chassis, and
optionally configuring it as a repeater in a repeater-assisted sys-
tem
• Initial start-up of a Redundant Transceiver Chassis.
Procedures for programming and troubleshooting the internal trans-
ceivers are contained in the Installation and Operation Manual supplied
with the transceivers.
Once the unit has been properly installed, configured and started up,
operation of the P20 Redundant Transceiver Chassis is completely
automatic. Operator actions are limited to observing the rear LED status
indicators for proper operation, and selecting A and B transceivers.
Following installation, we suggest keeping this guide near the equip-
ment for future reference.
2.0ABOUT THE P20
The P20 Redundant Transceiver Chassis (Figure 1) is a tabletop or
rack-mount unit designed to hold two WDS transceivers, two power
supplies, and a switchover logic board that automatically selects
between transceiver A or B as the active transceiver. (Manual selection
can also be made using a front panel switch.) Within a radio system, this
setup is called a Redundant Station.
