CDM-570/570L 1:1 IP Redundancy Configuration

The following steps are required for setting up a CDM-570 IP 1:1 redundant system using either
a CRS-170A (for the CDM-570L) or a CRS-180 (for the CDM-570) 1:1 Redundancy Switch:
1. First, the two CDM-570/570Ls will need an Ethernet connection to each other through a
Layer 2 switch or hub (preferably an L2 switch).
2. Before connecting the CDM-570/570Ls to the 1:1 switch, you will first need to configure
the following on the CDM-570/570L IP Module settings:
•
Administration
to DISABLED;
•
Administration
Working Mode;
•
Administration
Feature set.
3. On both modems, enter a unique IP Address that is on the same subnet (Interface
Ethernet Interface
to the other (Ops and Maintenance
4. On both modems, set Administration
Redundancy set to ENABLED. Save Parameters to Permanent Storage and power down
both modems.
5. Connect the CDM-570/570Ls to the1:1 switch:
•
•
6. While monitoring the Serial console CLI on both modems, observe the following after
powering on both modems at the same time (also observe the switch Online LEDs to see
which modem is the Online modem).

Redundancy Configuration
Working Mode: Both modems need to be set to the same
Features: Both modems need to have the same IP Option
IP Address). Verify that you can ping from one CDM-570/570L
Refer to Sect. H.4 for cabling with the CDM-570 IF
Refer to Sect. H.5 for cabling with the CDM-570L
Online modem CLI will display:
1:1 Redundancy (Auto Detected)
