Configuring CDM-570Ls for 1:1 Redundancy

CDM-570/CDM-570L/CDMR-570L Satellite Modem Installation and Operation
Manual (CEFD P/N MN/CDM570L.IOM)
For correct operation of the CRS-170A, the CDM-570L Satellite Modems must have
the following installed:
•
•
If the modems do not meet this requirement, contact Comtech EF Data. Firmware
updates are free and may be downloaded from the CEFD web page. Hardware
revision upgrades must be performed at CEFD.
Because the modem automatically detects if it is connected to a 1:1 redundancy system, the
steps required to configure both modems are minimal. Use each modem's front panel to fully
configure, monitor, and control the modem operation. The front panel keypad and display are
used to display all available options. Nested menus display all prompts needed to carry out a
required action. Refer to the pertinent modem's user manual for detailed configuration
information.
Alternately, configuration, monitoring and control of redundant systems is possible via remote
means over an EIA-485 multi-drop bus using the Serial console Command Line Interface, where
data is transmitted in asynchronous serial form using ASCII characters (see Figure 3-2). Refer
back to the modem manual for detailed information on either methodology.
