7. Link Alarm
Link Alarm allow user easily to identify and diagnose the
linking status. If set Link Alarm switch to Enable, UTP and
Fiber port can link up only when both linking conditions
are good. In addition, if any of the fiber or UTP port link
down during operation, the other port will also turn down
link to alert the user. Turn Link Alarm switch to Enable
provide user transparent link indication between two
network devices interconnected by ET-912Series Media
Converter.
If disable the Link Alarm. The UTP and fiber port will link
up base on their individual linking condition. Further, if
fiber port link down during operation, it will not turn down
the UTP port link and vice versa.
