Figure 6-5 - Redundancy With Heartbeat - Motorola APEX1000 Installation And Operation Manual

A properly configured and functioning Chassis Redundancy scheme requires you to:
•
Configure both APEXs by designating one as primary and the other as secondary
•
Configure the routes on the primary APEX
•
Configure the correct redundant APEX IP address (either ENET1 or ENET2)
•
Configure the redundancy mode, either
In hot redundancy mode, mappings are activated on both active and standby
APEXs (both APEXs join multicasts and process the input streams)
In warm redundancy mode, mappings are only activated on the active APEX
(only the active APEX joins multicasts and processes the input streams)
Additionally, the RF outputs from both APEXs must be wired into the same combiners
(only one APEX RF output can be active at any given time).
Because both APEXs are wired into the same combiners, all QAM channel outputs will
mute following a fault detection; this procedure enables the secondary QAM channels to
come online without colliding with primary QAM channels.
