Page 10: About This Manual
About this Manual This manual provides installation and operation information for the Comtech EF Data CRS-100 1:1 Redundancy Switch. This is a technical document intended for earth station engineers, technicians, and operators responsible for the operation and maintenance of the CRS-100 1:1 Redundancy Switch. -
Page 11: Important Information

Page 15: Chapter 1. Introduction
Chapter 1. INTRODUCTION The CRS-100 1:1 Redundancy Switch (Figure 1-1) is a companion product for use with Comtech EF Data CDM-500, CDM-550 or CDM-550T Modems. Its purpose is to continuously monitor a pair of modems (in a redundant configuration) so that, in the event of an equipment failure (or an undesired traffic condition), the unit will automatically switch data and IF signals from the failed unit to the Standby unit. - Page 16 Modems see identical Tx and Rx traffic signals all the time, which permits the CRS- 100 to continuously compare the fault status of both Modems. If the CRS-100 sees an identical fault on both Modems at the same time, it will infer that the fault condition exists in the external system, and eliminate an un-necessary switchover.

Page 17: Chapter 2. Installation
Be sure to keep all shipping materials for the carrier's inspection. If the unit needs to be returned to Comtech EF Data, please use the original shipping container. Mounting The CRS-100 is designed to be self-supporting at the rear of the two CDM-500/550/550T modems which it is connected to. -
Page 18: Configuration
These two switches control the conditions which initiate an automatic switchover. Consult the following sections on how to set these switches.

- Page 20 It is essential to ensure that the IF connections, both Rx and Tx, are made correctly, i.e. the Tx IF from Unit ‘A’ connects to the Tx IF port ‘A’ on the CRS-100, and Unit ‘B’ to ‘B’, and the same for the Rx IF connections. Failure to observe this requirement will result in the system malfunctioning.

Page 27: Chapter 4. Functional Description
Chapter 4. FUNCTIONAL DESCRIPTION The CRS-100 connects to two modems, an Online unit, and a Standby unit, monitors the fault status of these two units, and controls the routing of data and IF signals to and from the two units. In the case of an equipment failure, switching automatically takes place to protect the traffic circuit. - Page 28 Functional Description CRS-100 1:1 Redundancy Switch hence lose approximately 3.5 dB in output power level) the CRS-100 does not introduce any attenuation of output signal level. The Rx IF signal is fed to both units simultaneously, using an internal power divider.

Chapter 6. OPERATION AUTOMATIC OPERATION Having connected the cables in accordance with the instructions and diagram in Section 3.4, the User is now ready to put the system into operational use. Before proceeding, the User should check that the Auxiliary Serial link between the two units is functioning correctly. -
Page 32: Info) Misc (Miscellaneous Information)
On the bottom line, the screen should show that the 1:1 link is active. If it does not, then check that the cable is correctly installed before continuing. Comtech EF Data recommends that the User decide upon which condition is desired to initiate a switchover, and to correctly configure the two switches on the left side of the CRS-100. -
Page 33: Config) Mask (Alarm Mask)
‘ACTIVE’ and ‘MASKED’ is made. Comtech EF Data recommends that for most applications the CRS-100 should be configured to switch on Unit faults only. IMPORTANT The system, now configured, is ready to be put into service. -

This can be accomplished either by the User’s own software, or using Comtech EF Data’s own Monitor and Control Software package. If it becomes necessary to remove a Standby unit from the redundancy system, turn the power off before attempting to disconnect any of the cables. -
