3.2 Unpacking the Chassis
w/modules, bandpass and optional
trap filters
Thoroughly inspect the chassis with
modules and all other materials upon
their arrival. Axcera certifies that upon
leaving our facility the equipment was
undamaged and in proper working order.
The shipping containers should be
inspected for obvious damage that
indicates rough handling.
Remove the chassis and modules, along
with bandpass filter and optional trap
Filter, from the crates and boxes.
Check for dents and scratches or broken
connectors, switches, display, or
connectors. Any claims against in-transit
damage should be directed to the carrier.
Inform Axcera as to the extent of any
damage as soon as possible.
The modules are mounted to the chassis
assembly with slides that are on the top
and the bottom of the modules. There
are two thumb screws on the front panel
that hold each of the modules in place.
3.3 Installing the Chassis w/modules
and filters
The exciter/driver and power amplifier
chassis assemblies are made to mount in
a standard 19” rack. The chassis
assemblies mount using the four #10
clearance mounting holes on the ends.
The chassis should be positioned; to
provide adequate air intake into the front
and the air exhaust of the fan in the rear;
the ability to slide the modules out for
replacement purposes; the installation of
the bandpass filter; optional trap filter;
the coupler assembly; and output
transmission line. The chassis or cabinet
in which it is mounted should be
grounded using copper strapping
material.
NOTE: To pull out any power amplifier
module for replacement purposes, the
input and output coaxial cables must first
