The fault output is a dry contact relay and, depending on the configuration, it can be
used to report fault states by means of contact interruption. When the FN2012 is
switched off, the relay contact is deactivated (opened).
The following fault messages can be configured via the web interface:
● 'Fatal fault': Ethernet switch (modular) malfunction
● 'Ring fault': Ring faults are only displayed if the Ethernet switch (modular) has the
function of the 'redundancy manager'
● 'Ring port fault': 'Link down' state of a ring port
