CDM-840 Operation in 1:1 Redundancy

CDM‐840 Remote Router Installation and Operation Manual (CEFD P/N MN‐CDM840)
The CDM‐840 Remote Router automatically detects if it is connected to a 1:1 redundancy
system. With both units automatically configured for 1:1 operation, the online unit keeps the
offline unit updated as online unit configuration changes occur.
The user can also manually force backup of the online unit. Using the Redundancy section of the
CDM‐840 Web Server (HTTP) Interface 'Utility | Utility' page (Figure 3‐1), if the unit is part of a
1:1 redundant pair and this unit is currently online, click [Force Redundancy Switch] to force the
current unit to switch to standby mode.
