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 connecting the modems to the CRS-170A, you will need to first configure the
following IP module settings on the modems. From the modem front panel:
CONFIG
2 On both modems, set the redundancy to the Enable state:
CONFIG
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 the CRS-170A. Additionally, both modems will need an Ethernet connection to each
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 the user 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
2
Connect all cables – including the control cable, IF cable and data 'Y'cables – to the modems
and the CRS-170A.
