FX/TX LinkLoss and FiberAlert
During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an iMcV-FiberLinX-II receives valid link pulses, it knows that
the device to which it is connected is up, and that the copper or fiber cable coming
from that device is intact. The appropriate LNK (link) LED is lit to indicate this. For
troubleshooting information utilizing the LinkLoss and FiberAlert features of the iMcV-
FiberLinX-II modules, refer to Troubleshooting at the end of this manual.
** WARNING **
FiberAlert and LinkLoss features cause data interruptions designed to alert remote sites of line
failures. These data interruptions can be misinterpreted as module failures when these features
are enabled. Enable these features only when the resulting data interruptions and causes are
well understood.
FX LinkLoss
FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults to the
RJ-45 Data port to indicate that a fiber link fault has occurred.
TX LinkLoss
TX LinkLoss is a link integrity monitoring feature that forwards an RJ-45 link fault to
the fiber connected device to indicate that a link fault has occurred.
FiberAlert
FiberAlert minimizes the problems associated with the loss of one strand of fiber.
Normally when a single strand of fiber is lost, the transmitting side of the connection
