Note: By default, the APEX will enter a fault if an enabled GigE interface experiences a
link loss.
To configure the failover options listed, use the

Interface Fault Detection

Interface faults are based on link detection, not on data rate. By default, loss of link on an
enabled GigE interface causes a link fault. If transport stream redundancy is configured,
you must configure the APEX to failover only when both GigE interfaces lose link by
selecting either GigE 1 and 2 Link Loss and / or GigE 3 and 4 Link Loss. If you select
GigE 1 and 2 and both interfaces experience a link loss, then the APEX fails to the
standby.
•
When Link Loss is enabled on ENET1, it causes the APEX to enter a fault state when
the link is lost on the OAM&P control interface.
•
When Link Loss is enabled on ENET2, it causes the APEX to enter a fault state when
the link is lost on the ENET2 application interface.
Note: ENET2 link loss should not be enabled if a crossover cable is connecting the two
APEXs. Loss of power on one APEX in a direct connect mode causes the link to be down
on both APEXs.
