Transition Networks E-100BTX-SX-01 User Manual

The TRANSITION Networks Ethernet™ E-100BTX-SX-01 series 100BASE-TX to 100BASE-SX media converters connect 100BASE-TX unshielded twisted pair cable to 850 nm 100BASE-SX multimode fiber-optic cable, using either an ST connector (E-100BTX-SX-01) or an SC connector (E-100BTX-SX-01(SC)).
A four-positiion switch on the media converter allows selection of Auto­negotiation, half-duplex or full-duplex, and/or Link Pass Through (LPT) /Remote Fault Detection (RFD). An MDI/MDI-X switch allows straight- through twisted-pair cable to be used for crossover 100BASE-TX connections.

Switch Settings and Cable Requirements
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 requirementsare satisfied using the MDI/MDI-Xswitch with straight-through cable.
Set the MDI/MDI-X switch to MDI for cable connections between hub and media converter. Set the MDI/MDI-X switch to MDI-X for cable connections between media converter and terminal, transceiver or NIC.
Setting Switches
Use small flatblade screwdriver or similar device to set recessed switches. Refer to label on top of media converter for MDI/ MDI-X switch settings. Refer to drawing at left for four-position switch settings.
4-Position Switch (4th switch not used)
Auto-negotiation (UP) Detects and adapts to line
speed/operation mode of attached device. Full/Half-duplex (UP) Allows an attached full­duplex station to transmit and receive simultaneously. (DOWN) Allows an attached station to transmit and receive sequentially. LPT/RFD (UP) Blinks the SDF or SDC LED if a malfunction is detected at the unit to which the media converter is attached.
MDI/MDI-X Straight-Through/Crossover
1. Is the power LED on the media converter illuminated?
NO
Is the power adapter the proper type of voltage and cycle frequency for AC outlet?
Is the power adapter properly installed in the media converter and in the outlet?
Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
Proceed to step 2.
2. Is the 100BASE-SX SDC LED illuminated?
NO
Check UTP cables for proper connection and MDI/MDI-X switch position. (See above.)
Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
Proceed to step 3.
3. Is the fiber SDF LED illuminated?
NO
Check fiber cables for proper connection.
Verify that TX and RX cables on media converter are connected to RX and TX ports, respectively, on the other 100BASE-SX device.
