1. Introduction
1.1. Scope
This document describes the procedures required for installation of a basic
BroadAccess CAG40D-MIN in a 19” rack.
Note: The instructions in this manual are also relevant for the
CAGE40-MIN cage.
Note: If installing the CAG40D-MIN with the MPU-x, you should also refer
to the MPU-x Unit Installation Guide.
The document includes the following sections:
•Section 1 - Introduction: provides document and system overview.
•Section 2 - Site Preparation: explains how to prepare the site prior to
installation.
•Section 3 - Installation: explains how to install a CAG40D-MIN in a 19” rack
and basic rack configuration.
•Section 4 - Cable Connections: explains how to connect power, grounding and
communication cables to the system.
•Section 5 - Final Installation Activities: outlines the remaining activities
required to complete the installation of the system.
1.2. Compatibility
The CAG40D-MIN is compatible for use as a Remote Unit (RU) with
BroadAccess systems.

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.

Figure 1. CAG40D-MIN - Front View
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.

1.5. Safety Precautions
To avoid injury and prevent equipment damage, observe the following safety
precautions:
•Do not move or ship equipment unless it is properly packed in its original
wrapping and shipping containers.
•Observe ESD (Electrostatic Discharge) procedures when handling card.
•When connecting equipment to the DC voltage supplies, ensure correct
polarity.
•Equipment service and maintenance should be undertaken only by trained
personnel.
•Do not touch the backplane when system power is on.
•To prevent damage by lightning, ground the system units and add lightning
protectors to any lines that exit the building.
•Do not permit unqualified personnel to operate workstations used to manage
the system.
1.6. Inventory Check
Before installing the system, ensure that all the equipment to be installed has
arrived. At each site, remove the lists from their envelopes. Take the equipment
out of the boxes, and check that all the parts appearing in the lists have in fact
arrived.
If anything is missing in the order, do not continue with the installation without
conferring with an experienced installation technician. Make sure that the missing
equipment is received from the supplier. If you are uncertain whether or not to
continue with the installation before the missing equipment arrives, please contact
the Customer Support department.
