3.7 Removing and Installing System
Components
Note that the receiver does not have to be powered down
when components are removed or installed.
To Remove the CPM2 Module
The CPM2 charges the battery and provides low battery
voltage disconnect; removing the CPM2 module will
disconnect the battery and shut down the entire system if
AC power is not available. If the CPM2 must be removed
during an AC power failure, first connect a temporary battery
(protected with a 5A fuse and reasonably charged) to the
+BATT and GND terminals of the DML2A before removing
the CPM2.

MLR2-DV Installation Maximum Configuration

Remove the 4 retaining screws on the front panel of the
module. Slowly pull the module out of the metal cabinet.
After the CPM2 is replaced, remove the temporary battery
so that the CPM2 can properly maintain the main battery.
To Remove a Line Card Module
Remove the 4 retaining screws from the front panel of the
module. Slowly pull the module out of the metal cabinet.
To Install a Line Card Module
Adding a Line Card Module to the MLR2-DV requires the
addition of an MLRX Expansion Card Cage. Each MLRX
can hold two DVL2A modules. The MLRX is shipped with
power and communications bus cables.
