1.4. System Overview
The CAG40D-MIN, which serves as an RU, comprises a card cage into which all
cards required for operation are inserted. A CAG40D-MIN cage supports up to
128 subscribers.
The CAG40D-MIN can be installed with the MPU-x. The MPU-x (Mini Power
Unit) contains a charger and backup batteries for powering the CAG40D-MIN.
The CAG40D-MIN is supplied with a front door. The door assists in cooling the
cards by blocking the cage’s front opening, so that the airflow is directed upwards,
toward the cards. The door also protects the equipment, and contains a transparent
plastic window that enables easy monitoring.
The CAG40D-MIN cage with cards is shown in Figure 1.

The CAG40D-MIN can be installed as follows:
•Outdoor Cabinet (factory installed)
•standard 19” rack
There are three methods of installing the CAG40D-MIN :
•joined units configuration - CAG40D-MIN and MPU-x are assembled to form
a combined unit.
•separate units configuration - CAG40D-MIN and MPU-x are installed in
different locations.
•without the MPU-x unit - a different power supply feeds the CAG40D-MIN.
Note: In configurations where the CAG40D-MIN is installed in a 19’’ rack
separate from the MPU-x (or configurations where a different power
supply feeds the CAG40D-MIN), an optional adapter panel
(ADP-CAG-M) is required.
