IP Redundancy Configuration

Setup of the CDM-700/CDM-710/CDM-710G modems for 1:1 IP Redundancy (i.e., when the
terrestrial data type is GigE) is as follows:
Step Procedure
1
Before c onnecting t he m odems t o t he C RS-170A, y ou w ill ne ed t o f irst configure t he
following IP module settings on the modems. From the modem front panel:
CONFIG  AUX (Redundancy Mode)  ENA/DIS set to Disable.
2 On both modems, set the redundancy to the Enable state:
CONFIG  AUX (Redundancy Mode)  ENA/DIS set to Enable.
Press ENTER to save parameters to flash memory
3 Connect all cables – including the control cable, IF cable and data cables – to the modems
and t he C RS-170A. A dditionally, both modems w ill need an E thernet c onnection t o eac h
other through a Layer 2 switch.
4
Verify that one modem is ONLINE by the front panel LEDs; also verify that the ONLINE
LEDs for the CRS-170A indicate the same online state as the modems.
All configuration changes can only be made to the Online Modem and will
require you to "Save Parameters to permanent storage" to ensure
the configuration change is also applied to the Backup Modem.
3.6.2

Non-IP Redundancy Configuration

Setup of the CDM-700/CDM-710/CDM-710G modems for 1:1 Redundancy when the terrestrial
data type is non-Ethernet (i.e. HSSI, G.703) is as follows:
Step Procedure
1 On both modems, set the redundancy to the Enable state:
CONFIG  AUX (Redundancy Mode)  ENA/DIS set to Enable.
2
Connect all cables – including the control cable, IF cable and data 'Y'cables – to the modems
and the CRS-170A.
