Media Converter Port in Full-Duplex Network
CABLE SPECIFICATIONS (continued)
In a full-duplex network, maximum cable lengths are determined by the
cables used. See page 10 for cable specifications.
COPPER CABLE
NOTE: The 512-Bit Rule described below does NOT apply in a full-duplex
network.
Each RJ-45 connector requires 2 pairs of Category 5 rated cable.
The 50-pin Telco connector requires 24 pairs of Category 5 rated
cable.
Media Converter Port in Half-Duplex Network
The 512-Bit Rule applies separately to each collision domain.
USING THE 512-BIT RULE
Either shielded twisted-pair (STP) or unshielded twisted-pair (UTP) can
be used. DO NOT USE FLAT OR SILVER SATIN WIRE.
CATEGORY 5:
In a half-duplex network, maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet™ collision domain.
(Switches and routers divide the network into separate Ethernet™
collision domains.) The 512-Bit Rule determines maximum distances by
calculating the collision domain round-trip delay in bit-times.

To calculate a collision domain round-trip delay in bit-times, find the

terminal devices in the collision
domain. Calculate the round
trip delay by multiplying the
length of the cable (in meters)
by the delay per meter (in bit-

media converter port delays. If

Using LinkAlert™
OPERATION
The E-TX-FX-xx00 series multi-port media converter LinkAlert™ feature allows
each media converter port to pass 100BASE-TX-side link faults over the port link
to the 100BASE-FX side and to pass 100BASE-FX-side link faults over the port
link to the 100BASE-TX side.
Use the status LEDs to monitor multi-port media converter operation in the
network.
NOTE: Each 100BASE-TX/ 100BASE-FX media converter port is identified by
a number located just above the fiber connector(s) for that 100BASE-TX
/100BASE-FX port connection. The LEDs that apply to each 100BASE-TX or
100BASE-FX port connector(s) are located, when facing the multi-port media
converter, at the left of the connector(s) for that 100BASE-TX or 100BASE-FX
port connection.
If the port does not detect a good link on the 100BASE-TX side, the port disables
all transmission (including active-idle) on the 100BASE-FX side.
