Appendix A. CABLE DRAWINGS

A.1 Introduction

This appendix contains drawings of cables used with the CRS-280L L-Band IF Switch for 1:N Redundancy. These cables are broken into two
categories – Control Interface Cables and IF Interface Cables:

• The Control Interface Cables are used to connect the CRS-280L rear panel J1 CRS Control Interface or J2 SMS Control Interface

connector to its companion redundancy switch IF Switch Control Interface connector.

• The IF Interface Cables may be selected and used to connect the CRS-280L, via the front panel Tx/Rx Type ‘N’ threaded female

connectors, to the Redundant Modem and up to 10 traffic modems that are part of the 1:N redundancy setup, as well as to any
external uplink / downlink RF equipment.

Each section provides illustrations of the cables’ technical specifications; additionally, the table in each section cross-reference to the
illustrations found in
