MN-CDM850)
• CDM-840 Remote Router Installation and Operation Manual (CEFD P/N
MN-CDM840)
The CDM-850 and CDM-840 Remote Routers automatically detect connection 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.
Use the Redundancy section of the CDM-850 or CDM-840 HTTP (Web Server) Interface ‘Utility |
Utility’ page (similar to the page shown in Figure 4-1, but subject to update) to manually force
backup of the online unit. 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.
