7.1.1 Hardware Setup 
 
The hardware setup for a Compact Outdoor 1:1 Redundant System is very simple and  
involves the addition of (2) cables along with a redundancy switch. A schematic diagram of 
the redundancy setup is shown in Figure 7-6. 
 
The Link Cable is a simple (3) conductor crossover cable that allows the system to pass 
command and control between amplifiers.  With the redundancy kit, this cable is supplied in a 
26 inch (660mm) length. 
 
The Switch Cable is a “Tee” configuration and connects between each amplifier and the 
redundancy switch. The Redundancy Switch is a –28 VDC type. Therefore the controller in 
each Compact Outdoor Amplifier is capable of supplying +28 VDC to the common voltage 
input. Either controller may then provide a (sink) return to engage either position 1 or position 
2 of the redundancy switch. 
 
Care must be observed when connecting this cable to the amplifiers. The cable end labeled  
“A1” must be connected to the amplifier whose output is connected to Port 3 of the waveguide 
switch.  Likewise the cable end labeled “A2” must be connected to the amplifier whose output 
is connected to Port 1 of the waveguide switch. This is for proper identification purposes of 
the Redundancy Control Firmware used by each Compact Outdoor Amplifier.
