Chapter 3. Unpacking and Installation
This section provides unpacking and installation instructions.
3.1 Installation Requirements
The gateway is designed to be installed within any standard 19-inch (48.26 cm) wide equipment cabinet
or rack. It requires one rack unit (RU) of installation space (1.75 inches/4.45 cm) vertically and 13.0
inches (33.0 cm) of depth. Including cabling, a minimum of 16.0 inches (40.64 cm) of rack depth is
required. The rear panel of the gateway has power entering from the left and IF Cabling entering from the
right (as viewed from the rear of the gateway). Data and Control Cabling can enter from either side.
Please refer to Section 4 for rear panel connector descriptions and pinouts. The gateway can be placed
on a table or suitable surface if required.
WARNING
PROPER GROUNDING PROTECTION
During installation and setup, make sure that the gateway is properly
grounded. The equipment shall be connected to the protective earth
connection through the end user protective earth protection.
Also, make sure that the IF input and output coax cable shielding are correctly
terminated to the Chassis ground.
WARNING
ELECTRICAL SHOCK HAZARD
There are no user-serviceable parts or configuration settings inside the
Chassis. A shock hazard exists internally at the power supply module.
DO NOT open the Chassis under any circumstances.
IMPORTANT
 When installing the gateway in an equipment rack or any other method,
adequate ventilation must be provided.
 The ambient temperature inside the rack must be between 0 
and 50

C, and
held constant for best equipment operation.
 The air available to the rack must be clean and relatively dry.
 The gateways must not be placed immediately above a high-heat or EMF
Generator to ensure the output signal integrity and proper receive operation.
 DO NOT install the gateway in an unprotected location where there is direct
contact with moisture, rain, snow, wind or sun.
