4.2.5 Redundancy Configuration
Redundancy is available when two units are used to ensure reliable service in the event of failure of a
unit. The units are configured in Primary/Backup roles and communicate between each other using a
serial cable (Part Number CA-0000011) connected to each unit’s redundant port and via Ethernet.
Other Unit’s IP Address
Enter the IP address of the unit to be used in conjunction with this unit for redundant functionality.
Mode
Select the mode of this receiver (Primary, Backup, Disabled). If two units are to be configured as a
redundant system, then one unit must be "Primary" and the other must be "Backup". Please note that both
units must be configured correctly (one as primary, the other as backup) in order for redundancy to
function correctly.
IMPORTANT
Note: CMR Redundancy does not automatically configure the backup unit when changing the
primary, or vice versa. Each unit must be independently configured when changes are required.
