1-12 Physical Description DXC-100PSX

Broadband Redundant Module, DE3T3/R

The Broadband Redundant Module is designed to interface with the DXC-100-

resident standby DT3 or DE3 interface module via a set of BNC interconnection

cables. This module is used to facilitate DXC-100-commanded interface switching

to the standby module from the protected module (via latching relays). The

Broadband Redundant Module must be installed in DXC-100PSX slot 7 for

Broadband Group 2, or in DXC-100PSX slot 11 for Broadband Group 1. The

standby DT3 or DE3 module set must be installed in a matching slot (slot 7 or 11)

in the DXC-100 chassis.

Thumbscrews are provided at the top and bottom of the faceplate to secure the

module in the chassis and to make an electrical connection to frame ground for

regulatory emission compliance. See
