7.4 Module Care

The EOCell Amplifier module, Fiber Optic Transceiver 48V Power Supply module

and optional Alarm module contain semiconductor devices that are susceptible to damage

from electrostatic discharge (ESD). Correct handling of modules is mandatory to ensure

long-term reliability.

Furthermore, to prevent electrical damage to modules during the removal or installation

process, disconnect the BDA from the AC power source.

7.4.1 Module Removal

Verify that AC power to the BDA has been removed.

Disconnect the system RF or fiber optic cable as required.

3 Loosen the module’s top and bottom wedge locks using a 9/64”allen wrench. (Not

Applicable for Duplexer Module).

4 Loosen the module’s front plate screws.

5 Slowly but firmly, pull the module straight out of the chassis. Take care not to twist or

turn the module during withdrawal. The RF connectors on the rear of the module are

easily damaged if handled carelessly.

7.4.2 Module Installation

Verify that AC power to the BDA has been removed.

Carefully align module into its location and then slowly push the module directly straight

fully into its position. Take care not to twist or turn module during installation.

3 Fasten front plate module screws.

4 Tighten module top and bottom wedge locks using a 9/64” allen wrench. (Not Applicable

for Duplexer Module).

5 Verify all modules are connected prior to applying AC power.

6 Connect the system RF and Fiber Optic cables to BDA.
