Operation
Using status LEDs
Use the status LEDs to monitor the media converter operation in the network.
Power Steady LED indicates connection to external AC power.
Fiber Steady LED indicates fiber link connection.
Copper Steady LED indicates copper link connection.
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to be used with 100Base-
TX ports. Using Auto-Negotiation, the media converter brings up the copper links
in the highest speed and mode possible for all attached network devices.
Full-Duplex network
In a full-duplex network, maximum cable lengths are determined by the type of
cables that are used. See page 1 (front cover) for the cable specifications for the
different J/FE-CF-03 models. (The 512-Bit Rule does not apply in a full-duplex
network.)
Half-Duplex network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the round
trip delay limitations of each Fast Ethernet™ collision domain. (A collision domain
is the longest path between any two terminal devices, e.g. a terminal, switch, or
router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating
the round-trip delay in bit-times (BT) of a particular collision domain. If the result
is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled “Collision
Domains” on the Transition Networks website at:
