Configuring LinkLoss and FiberAlert

this manual to determine what features your module offers as well as the jumper
locations and ON/OFF positions.

Auto-Negotiation on McLIM TX/FX and TX/SX
When Auto-Negotiation is enabled, the media converter negotiates as a 100 Mbps
Full-Duplex device; if the device the media converter is connected to can operate at
100 Mbps Full-Duplex, a link will be established.
If the twisted pair port on the other device does not have the ability to auto-
negotiate, or if a 100 Mbps Half-Duplex connection is desired, Auto-Negotiation on
the media converter must be disabled. Half- and Full-Duplex settings must be
manually set and match on both end devices to which the media converters are
connected.
