Missing RF Modules
When an RF module in a host or remote no longer communicates with the system
controller
, the module’s status changes to
Missing
and the gray bar of a missing module
cannot be expanded.
To re-establish connection to the system controller, disable the RF module by making it
Unavailable, and then re-enable it. See
Making an RF Module Unavailable
If an RF module is missing because of maintance activities, you can also use the Module
Availability feature to hide the module and its associated alarms in the EMS. RF Modules in
Standby and Failed states can also be made Unavailable.
