Transition Networks E-100BTX-FRL-03(SC) E-100BTX-FRL-03(SM), E-100BTX-FRL-03SM, E-100BTX-FRL-03 User Manual

The TRANSITION Networks Ethernet™ 100BASE-TX to 100BASE-FX media converters
connect 100BASE-TX unshielded twisted pair cable to 100BASE-FX multimode OR
singlemode fiber-optic cable. Media converter models are selected according to the
fiber mode and fiber connector required at the site. Multimode fiber-optic cable can use
either an ST connector (E-100BTX-FRL-03) or an SC connector (E-100BTX-FRL-03(SC)).
Singlemode fiber (E-100BTX-FRL-03(SM)) uses only an SC connector. All media
converters function in half-duplex mode or, when connected to devices capable of full­duplex connectivity, in full-duplex mode. An MDI/MDI-X switch allows straight-
through twisted-pair cable to be used for crossover 100BASE-TX connections.

CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE
PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in
damage to the public telephone network.

Straight Through/Crossover Cable Requirements and Pin Specifications

The two active pairs in a
100BASE-TX network are pins
1 & 2 and pins 3 & 6. Use only
dedicated wire pairs (such as
blue/white & white/blue,
orange/white & white/orange)
for the active pins.

Straight-through/crossover 100BASE-TX requirements are satisfied
using the MDI/MDI-X switch with straight-through cable.

100BASE-TX cable connections between a hub and the media
converter require the MDI/MDI-X switch to be set to MDI.

100BASE-TX cable connections between the media converter and a
terminal, transceiver or NIC require the switch to be set to MDI-X.

Using small flatblade
screwdriver or similar
tool and referring to
label at front of media
converter, set
MDI/MDI-X switch
position for site
installation.
