CRS-170A L-Band 1:1 Redundancy Switch Preface Revision 3 MN/CRS170A.
Chapter 1. INTRODUCTION 1.1 Overview Figure 1-1. CRS-170A L-Band 1:1 Redundancy Switch The CRS-170A L-Band 1:1 Redundancy Switch module, shown in Figure 1-1, is an L-Band Tx-Rx IF signal switch designed for use with L-Band satellite modems in a 1:1 configuration.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM The receive side of the switch uses both power dividers and relays to provide the redundant modem interface for three signals multiplexed onto the LNB coaxial cable: • 950-1950 MHz L-band RX RF from LNB • 10 MHz frequency reference to LNB • DC power supply to LNB The CRS-170A monitors the faults of both modems and determines which modem should be online.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM In both cases, the CRS-170A is controlled by the supporting data switch, and places the “A” or “B” modem RF on-line to match the data switch state. The CDM-600L (CLM-9600L) modems supply redundant power to the CRS-170A through the CRS-150. The SMS-301 itself has redundant power supplies, and feeds power to the CRS-170A through the control cable.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM 1.1.2 Antenna Side Connectors Two 50Ω female Type ‘N’ connectors on the antenna side of the CRS-170A L-Band 1:1 Redundancy Switch module provide the coaxial cable connections to the outdoor transmit and receive equipment (BUC and LNB). Refer to Figure 1-3 and the accompanying table for details (this image depicts the Rev. A and later versions of the CRS-170A; see Figure 4-1 for the original version).
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM 1.2.1 Operation with CDM-625, CDM-570L, CDM-700 and CDM-710 The CRS-170A is configured with two modems to form a complete 1:1 redundant modem. Software built into the modem M&C and cross connected status and communication between the modems allows the M&Cs to jointly function for 1:1 switch control.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM modem from interfering with the Rx data traffic. Send timing output from the offline modem is also TRI-STATE®1 . The User determines the conditions, which cause an automatic switchover. This is controlled by two switches at the front of the unit labeled Switch Conditions, and the User can select between Unit faults only, Unit faults or Receive Traffic faults, Unit faults or Transmit Traffic faults, or all three.
CRS-170A L-Band 1:1 Redundancy Switch Introduction 1.2.1.1 Revision 3 MN/CRS170A.IOM IP Data 1:1 Switching Functional Description A standard Ethernet Layer 2 Switch (provided by User) is needed when a CDM-625/570L/700/710 modem is configured for Ethernet terrestrial traffic. Figure 1-4. IP 1:1 Redundancy For IP 1:1 redundancy operation, both modems are assigned a unique M&C IP address on the same subnet (in the diagram above, 172,18.10.21/24 and 172.18.10.22/24).
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM Figure 1-5. 1:1 Redundancy Switchover All configuration changes can only be made to the Online Modem and will require the User TO “SAVE Parameters to permanent storage” TO ENSURE THE configuration change is also applied to the Backup Modem. 1.2.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM At the heart of the CRS-150 is a Controller State Machine that is responsible for fault monitoring and control of switching functions – it is implemented in a CPLD. The CRS-150 redundancy switch derives its operating power from the two modems (online and standby units) via extra power-carrying wires in the data cable from each modem.
CRS-170A L-Band 1:1 Redundancy Switch Introduction Revision 3 MN/CRS170A.IOM 1.2.4 Operation with SDM-300L3 and SMS-301 The SMS-301 is modified from the standard version that operates with 70/140 MHz IF SDM300A modems. The BNC IF connectors are removed since the connectors and internal switching are not suitable for L-Band operation. Signals on the Status/Faults connector (J14) are modified to provide +12VDC power output and A/B switch control outputs to the CRS-170A.
CRS-170A L-Band 1:1 Redundancy Switch Introduction 1.3 Revision 3 MN/CRS170A.IOM Summary of Specifications Equipment Type L-Band 1:1 Redundancy Switch Manufacturer Comtech EF Data, Tempe, Arizona Comtech EF Data Modems Supported • • • • • • • Operating Modes • Fully Automatic under control of supporting 1:1 switch. • Manual under control of supporting 1:1 switch.

Chapter 2. INSTALLATION 2.1 Unpacking and Inspection The CRS-170A L-Band 1:1 Redundancy Switch module and its Installation and Operation Manual are packaged and shipped in a pre-formed, reusable cardboard carton containing foam spacing for maximum shipping protection. CAUTION Do not use any cutting tool that will extend more than 1” into the container and cause damage to the unit. Be sure to keep all shipping materials for the carrier's inspection.
CRS-170A L-Band 1:1 Redundancy Switch Installation 2.2 Revision 3 MN/CRS170A.IOM Mounting The CRS-170A is designed to be freestanding, or mounted in the rear of a rack containing the modems. Because of the module’s small size and weight, one installation option is to let the module hang freely, supported by the interfacing cables. Alternatively, the available Comtech EF Data Mounting Panel Kit KT/10254 allows the module to be mounted to the rack horizontally or vertically as shown in Figure 2-1.
Chapter 3. MODEM AND SWITCH CONFIGURATION 3.1 Overview IMPORTANT In order to avoid damage to the modems and CRS-170A switch, it is important for the user to first configure the modems for 1:1 redundant operation as outlined in this chapter. Once the modems have been properly configured for 1:1 redundant operations, the user should then set the DIP switches on the CRS-170A to the correct modem selection (see Section 3.7 CRS-170A Switch DIP Settings).
CRS-170A L-Band 1:1 Redundancy Switch Modem and Switch Configuration 3.2 Revision 3 MN/CRS170A.IOM Configuring CDM-625s for 1:1 Redundancy Because the CDM-625 can detect if it is connected to a 1:1 redundancy system, the steps required to configure both modems is minimal. Before connecting the modems to the CRS-170A, follow the below procedures if applicable. If terrestrial data is not Ethernet and CnC will not be used, then no modem 1:1 redundancy configuration is needed. 3.2.
