Failover Sequence; Qam Rf Redundancy Window - Motorola APEX1000 Installation And Operation Manual

Failover Sequence

In the event of port failure on an APEX1000 connected to a REM1000, the following
sequence of events takes place:
1. The APEX1000 detects a failed QAM channel, RF Port, or QAM Module, and issues
a standard SNMP trap alarm.
2. The APEX1000 mutes the failed RF port, and configures the backup port identically
to the failed port.
3. The APEX1000 re-routes mapped services from the failed port to the backup port.
4. The APEX1000 transmits a message commanding the REM1000 to switch to its
redundant port, and issues the RF failover SNMP trap.
5. The APEX1000 receives confirmation of the switch-over from the REM1000,
un-mutes the backup port, and updates the status.

QAM RF Redundancy Window

Use the QAM RF Redundancy window to define the connection type for RF Redundancy
and set (or suspend) failover.
After configuration is complete between the two APEXs and the REM, use this window
to monitor Redundancy and Failover status, or to make further changes to the
configuration.
