The IE-MiniFiberLinX-II ships from the factory with Auto Negotiation enabled on the
twisted pair port. In this mode, the port automatically negotiates for speed and
duplex.
The twisted pair port on the IE-MiniFiberLinX-II can also be manually set for 10 Mbps
or 100 Mbps operation and for Half- or Full-Duplex (i.e. 10 Mbps Full-Duplex, 10
Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps Half-Duplex).
Selective Advertising, when used in combination with Auto Negotiation, advertises
only the configured speed and duplex mode for the twisted pair port. If a specific
speed and/or duplex mode is desired, Selective Advertising should be used rather
than Force Mode, when connecting to devices that ONLY Auto Negotiate.
Bandwidth Control
The IE-MiniFiberLinX-II includes bi-directional bandwidth control, which can be
independently set in 32 Kbps increments up to 100 Mbps. Bandwidth control can be
configured through iView² or a console session. The device features an integrating
algorithm with a 64 Kb buffer, allows traffic bursts, to prevent lost data.
This allows
operators to offer tiered services. See the iView² for configuration information.
FX LinkLoss, TX LinkLoss and FiberAlert
During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an IE-MiniFiberLinX-II receives valid link pulses, it knows the
device to which it is connected is up, and the copper or fiber cable coming from that
device is intact. The appropriate link LED is lit to indicate this. For troubleshooting
information using the LinkLoss and FiberAlert features of the IE-MiniFiberLinX-II
modules, refer to the Troubleshooting section of this manual.
WARNING
The FiberAlert and LinkLoss features cause data interruptions designed to alert remote sites of
line failures. These data interruptions can be misinterpreted as module failures if these features
are not enabled properly. Enable these features only when the resulting data interruptions and
causes are well understood.
FX LinkLoss
FX LinkLoss is 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.
