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.

OUTPUT SAMPLE

Figure 7-6: 1:1 Redundant System with Link Cable and Switch Cable installed

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.
