C.3.2.3 Redundancy Operation via the Web Server Interface
Figure C-6. CDM-740 Web Server Interface Utility page
From the CDM-740 Web Server Interface the ‘Utility’ page (Figure C-6) provides the user with
the means to load or save a modem configuration, and control operation of the CDM-740 as part
of a 1:1 Redundancy setup.
In the Redundancy section, to define the Current Redundancy State, use the dropdown menu
to set the status as Online or Offline.
Once the Current Redundancy State has been established, click [Force Redundancy Switch]
to force the unit to toggle the Unit Fail relay to the “fail” state for approx 500ms. If the unit is part
of a 1:1 pair, and it is currently the ‘Online’ unit, this will force a switchover, so the unit will then
be in ‘Standby’ mode. The command is always executed by the unit, regardless of whether it is
stand-alone or in a 1:1 pair.
For complete details on using the CDM-740 Web Server Interface, refer to Chapter 6.
