Operating Environment
Before operating the node with the digital reverse modules installed, ensure that the
operating environment meets the following standards.
Ambient temperature range outside the node must be maintained between -40°C
and +60°C (-40°F to 140°F).
Storage temperature range of the digital reverse modules must be maintained
between -40°C to +85°C (-40°F to 185°F).
Humidity range must be maintained between 5% to 95% non-condensing before
installation of the bdr digital reverse module(s).
To Install the Transmitter Module
The bdr transmitter module uses the same style housing as the optical receivers and
transmitters, except that it uses double-wide module housing. As such, it occupies
two standard transmitter positions in the node lid.
The following illustration shows the location of the installed modules in the node.
