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. The Tx (transmit) side switches four modem output signals that are multiplexed onto the transmit coaxial cable: 950-2250 MHz L-band transmit RF;...

Similarly, the SDM-300L3 requires an SMS-301 switch together with the CRS-170A. In both cases, the CRS-170A is controlled by the supporting data switch, and places the “A” or “B” modem RF online to match the data switch state. The CDM-600L (CLM-9600L) modems supply redundant power to the CRS-170A through the CRS-150.
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 its accompanying table for details (this image depicts the Rev.
OR’d so that the switch remains active if power is lost from one of the modems. Mode Switches – The Mode DIP switches, located on the antenna side of the CRS-170A, allow the switch to operate in two different modes: Normal (Intelligent Controller) Mode and SDM-300L/CDM-600L (Dumb Controller) Mode.

Modem Unit faults or Receive Traffic faults; Modem Unit faults or Transmit Traffic faults; or all three. Also located on the antenna side of the CRS-170A are two green LEDs that indicate which modem is Online. With the ‘bridging’ architecture of the CRS-170A (whereby identical terrestrial data traffic signals are routed to both Online and Offline modems), the redundancy controller can avoid unnecessary switchovers.
CRS-170A L-Band 1:1 Redundancy Switch Revision 10 Introduction MN/CRS170A.IOM 1.2.1.1 1:1 IP Redundancy Data Switching – Functional Description 1.2.1.1.1 CDM-570L (with Optional IP Module) – Managed Switch or Router Modes • Do not use the M&C Ethernet port (bottom RJ-45 connector) when the optional IP Module is installed.
CRS-170A L-Band 1:1 Redundancy Switch Revision 10 Introduction MN/CRS170A.IOM Any new packets arriving destined for that MAC address will be forwarded only out the port identified in the CAM table. Most switch CAM tables do have a flush or timeout value, but is normally set to a very high number to limit the amount of times the switch has to broadcast a packet out all ports.

CRS-170A L-Band 1:1 Redundancy Switch Revision 10 Introduction MN/CRS170A.IOM Note the following: 1. The Managed Switch Mode method of redundancy is intended to be equivalent to pulling the Ethernet cable from one port and putting it into a different port on the same switch.
CRS-170A L-Band 1:1 Redundancy Switch Revision 10 Introduction MN/CRS170A.IOM Whichever modem is online will assume the Traffic IP. When there is a switchover to the backup modem, this modem will now assume the Traffic IP. Per Figure 1-9, the backup modem will also broadcast a “gratuitous ARP” which will tell all local devices to now associate a new MAC address for the Traffic IP 172.18.10.20.
10MHz reference signals, DC power for the BUC and LNB, and FSK signaling to the BUC are switched in the CRS-170A under control of the CRS-150. In the case of an equipment failure, automatic switching takes place to protect the traffic circuit.

LED will illuminate on the front of the CRS-150 to indicate whether the ‘A’ or ‘B’ unit is online, and a green LED on the antenna side of the CRS-170A will indicate the same status. DIP switches on the CRS-170A’s front panel are set to establish modem-specific operation. With the CDM-600L (CLM-9600L), place the Mode switch in the SDM-300L/CDM-600L (CLM-9600L) position and push the Switch Condition switches to the OFF position.
IF signals, 10MHz reference signals, DC power for the BUC and LNB, and FSK signaling to the BUC are switched in the CRS-170A under control of the SMS-301. In the case of an equipment failure, automatic switching takes place to protect the traffic circuit. Consult the Comtech EF Data SMS-301 Redundancy Switch Installation and Operation Manual for detailed information on operation of the SMS-301.
