is unaware that there is a fault. FiberAlert returns faults back on the fiber they came
in on.
Using LinkLoss and FiberAlert
In a typical central site to remote site media conversion, it is recommended that the
enable the LinkLoss and FiberAlert features are enabled as indicated in the following:
FiberAlert and LinkLoss
Feature Enabled Fault Location Port affected
FiberAlert Remote Side Only Fiber Fiber
TX LinkLoss Remote Side (or both) Twisted Pair Fiber
FX LinkLoss Host Side (or both) Fiber Twisted Pair
** WARNING **
Do not enable FiberAlert on both modules when using iMcV-FiberLinX-II in pairs. This will
cause them to lock up when a fault occurs on the fiber. Only enable FiberAlert on the
remote module.
Link Fault Pass Through (LFPT)
Link Fault Pass Through is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote modules. LFPT is enabled by turning on
both FX and TX LinkLoss on both modules. This feature allows either end of the
conversion to detect a link fault occurring at the other end of the media conversion
chain.
Regardless whether a break occurs on a copper or fiber segment between the End
device and the media converter, or between the two media converters, End devices
at both ends.
