Overview
Physical Characteristics
Refer to Appendix titled Mechanical Drawings for the Physical
Characteristic Specifications of your amplifier.
The Xicom Solid State ODUs are air cooled where the outside
cooling air does not pass through the SSPA and power supply
enclosure. The SSPA and power supply are conduction cooled.
They are mounted on a finned aluminum plate. A fan pushes
outside air through the fins keeping moist cooling air separate from
the electronics and power supply.
The power supply is field replaceable. See the appendix titled
Mechanical Drawings for a detailed drawing illustrating removal.
The appendix titled SSPA Power Supply Removal Procedure
contains step by step instructions for removing the power supply
module.
Environmental Specifications
Table 1, Environmental Specifications, lists the typical amplifier
environmental specifications.
Refer to the appendix titled Specifications for the environmental
specifications unique to your amplifier.
The amplifier is designed to operate in rain and snow. However, in
high snow load conditions it is advisable to provide a snow shroud
to prevent a buildup of snow at the air inlet causing a blockage that
will reduce air flow.
