14.2.11 Configuring redundancy management
In the 'Redundancy management configuration' element, you can configure
redundancy management for Ethernet networks that have several Ethernet
switches (modular) FN2012 [➙ 137].
You will find the 'Redundancy management configuration'' element in the 'Network'
> 'Global system configuration' > 'FS720 network configuration' > 'Ethernet sub-net'
task card.
For the 'Redundancy management configuration', the 'Type of redundancy
configuration' can be configured manually on the 'Overview' tab.
You cannot make an
y manual configuration settings if you opt for the '
Automatic
'
configuration.
The '
Loop wired network
' configuration requires you to configure the '
Redundancy
manager' manually.
The '
Stub wired network
' configuration requires you to manually
configure the
suppression of ring and port faults for the external ports.
The following chapters describe the various configuration types for 'Redundancy
management configuration'.
14.2.11.1 Automatic configuration
For automatic configuration, the value 'Automatic' is set in the 'Type of redundancy
configuration' field.
Automatic configuration for 'Redundancy management configuration' is the default
configuration for a ↑ 'Site'. You cannot make any manual configuration settings if
you opt for automatic configuration.
In an automatically configured Ethernet network with several 'Stations', an FN2012
has the function of the 'Redundancy manager' allocated to it by the system. The
'Redundancy manager' is defined automatically in the Ethernet network. Ring faults
and port faults are not suppressed.
If a '
Site
' only has one '
Station
' or if the '
Station
' is not linked to any other '
Station
'
via an Ethernet network, ring faults and port faults are suppressed automatically.
Automatic configuration cannot be used if the fire detection system is configured
with a 'Stub wired network'. Manual configuration is required for a 'Stub wired
network'.
