2-2. DIP Switch with Link Mode
An ST/SC/MT-RJ/VF-45 connector provides the link to the multi-mode fiber
cabling or single-mode fiber cabling, and two LED indicators show the status of
the Module at-a glance. A DIP-switch sets the operating mode to half-duplex or
full-duplex (default).

2-3. LED Descriptions
There are two LED indicators for each of the Fiber connection ports. If there is no
connection to a port, the corresponding LED indicators are not lit.
•
Link/Activity
. This LED indicator is green when there is a connection secured
to a device (a link) to the corresponding port. The LED indicator blinks when
there is a transmission of data (activity) taking place at the corresponding port.
•
Duplex Mode/Collision
. This LED indicator is orange when the
corresponding port is operating in Full Duplex mode. When the corresponding
port is operating in Half Duplex, the LED indicator is not lit. When collisions
are occurring at the corresponding port, the LED indicator blinks.
