3.2.7 Fan unit
The fan unit is used for cooling the installed components within the DIB-R5 flexibleTx.
The air filter pad is affixed to the inside of the front door and filters the dirt and dust parti-
cles from the air.
The fan unit is implemented in the form of a fan subrack for the DIB-R5 flexibleTx and
contains six fans. For every fan, the state is signaled via an LED so that the status is
visible from the outside. The ambient temperature is continuously being monitored and
the fan speed is adjusted accordingly. In addition, the fans of the cavity combiner are
being monitored.
The following figure shows the front view of the fan unit. The following table describes it in
detail.
