GENERAL DESCRIPTION
PHYSICAL
Figure 1-1. Front View, 1:1 Redundant Line Amplier System
Figure 1-2. Rear View, 1:1 Redundant Line Amplier System
The 1:1 Redundant Line Amplier System is designed
to ensure continuous operation without disruption of
signal transmission. An amplier fault can be repaired
and/or routine maintenance can be performed with out
signal disruption.
If a fault is detected and the unit is in automatic
mode, the faulted amplier is switched off-line by
physically removing its input and output signal lines
and connecting them to the backup amplier. The line
amplier unit also provides manual switching of the
ampliers.
The system stores all information in non-volatile
memory. If power is lost, the amplier will return to its
original settings when power is restored.
The remote interface provides control and status of the
amplier unit from a remote location.
FEATURES
Fault tolerant design
Fully redundant, hot-swappable power supplies
Remote control via RS485 or RS422 (user selectable)
Automatic/manual control from both local and remote
mode
Remote status
Off-line input/output access
Amplier current fault detection

SECTION 2: INSTALLATION
UNPACKING, STORAGE, RESHIPMENT
Carefully open the shipping container and remove the equipment. Inspect the equipment thoroughly and report any
damage.
If the equipment is to be stored, it should be wrapped in plastic and kept in a clean, dry place.
If the equipment is to be reshipped for any reason, wrap in heavy plastic and ship in a heavy (275 lb. test) double wall
carton. At least three inches of a solid packing material should be used on all sides of the unit. The carton should be
marked to indicate that it contains fragile electronic equipment.
MOUNTING
Slides are provided for mounting in a standard 19” equipment rack.
TURN-ON PROCEDURE
After mounting, make all external connections per Table 2-1. Refer to next subsection for proper system conguration.
Refer to Section 1 for the physical conguration of the 1:1 Redundant Line Amplier System.
Apply power to the equipment using the power On/Off switches located on the rear panel of the unit..
All Power Supply and Unit Fault lights should be off.
System is now operational.
