Non-IP Redundancy Configuration

Do these steps for setup of the CDM-710GL, -710, or -700 modems for 1:1 Redundancy when the
terrestrial data type is non-Ethernet (e.g., ASI, HSSI, G.703):
Step Task
1
Enable the redundancy state for both modems. From the modem front panel:
CONFIG: AUX (Redundancy Mode)  ENA/DIS – set to Enable.
2
Connect all cables – including the control cable, IF cable and data cables – to the modems and the CRS-170A.

IP Redundancy Configuration

Do these steps for setup of the CDM-710GL, -710, or -700 modems for 1:1 IP Redundancy (i.e., when
the terrestrial data type is Gigabit Ethernet (GigE or GbE)):
Step Task
1 Before connecting the modems to the CRS-170A, you must first configure the following IP module settings on
each modem. From the modem front panel:
CONFIG: AUX (Redundancy Mode)  ENA/DIS set to Disable.
2 Enable the redundancy state for both modems. From the modem front panel:
CONFIG: AUX (Redundancy Mode)  ENA/DIS set to Enable.
Press ENTER to save your settings.
3
Connect all cables – including the control cable, IF cable and data cables – to the modems and the CRS-
170A. Additionally, you must use a Layer 2 switch to establish an Ethernet connection between each modem.

4 Verify that the ONLINE LEDs for the CRS-170A indicate the same online state as displayed by the modems'
front panel LEDs.
