For large Matrix systems in which network redundancy and visibility is critical,
redundant system controllers provide uninterrupted monitoring and control of hosts and
remote units.
A Primary controller can display and make configuration changes through the EMS,
while a Secondary, or backup controller provides a read-only view. If a Primary
controller fails, you can manually switch to the Secondary controller.
Redundant system controllers adhere to the following rules:
System controllers are unaware of each other and do not communicate directly
Failed system controllers that have been recovered will restart in the Primary or
Secondary role last used
Only one system controller appears in the EMS system tree at a time. For
example, log into the Primary controller to see it at the top of the tree. The
Secondary controller is not visible
If a system controller fails and you can't log into the EMS, RF
signals can still be transmitted and received on the uplink and
downlink path as long as there are no Critical alarms.
