Gigabit Media Converter Module – Installation Guide
7
Pass-Through enabled, a loss of fiber link on either the transmit or
receive line will be passed through to the local copper connection
thus notifying the connected device.
If the Media Converter Module has been set to Smart Link Pass-
Through mode, the effect will be the same as FFA, since the link
loss on the fiber receiver will result in bringing down the copper
link, which will in turn cause the transmit fiber link to be brought
down.
Note: This feature only takes effect if Fiber Negotiation has been
turned OFF.
The following diagram is an illustration of the operation of this
feature.
(A) – Remote Media Converter setup for Fiber Fault Alert -
Enabled, Fiber Negotiation – OFF and Link Mode – Normal.
