1. Is the power LED on the media converter illuminated?
NO
• Is the Slide-In-Module properly connected to the Media Conversion Center
chasis backplane?
• Is the Power Supply Module properly connected both to the Media
Conversion Center chasis backplane and to the AC outlet?
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the 100BASE-TX SDC LED illuminated?
NO
• Check UTP cables for proper connection and pin assignment. (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.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
Troubleshooting
The physical characteristics of the media cable must meet or exceed IEEE
802.3u 100BASE-TX and 100BASE-SX specifications.

Installing Slide-In-Module(s)
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when installing Media Converter Slide-in-Module(s) in the 16-Slot Media Conversion
Center. Failure to observe this caution could result in damage to, and subsequent
failure of, the Media Converter Slide-in-Module(s).
NOTE: Slide-in-Modules can be installed in any installation
slot, in any order.
To install the Media Converter Slide-in-Module in the E-MCC1600 chassis:
1. Ensure that switches on circuit board are set correctly for
site installation.
2. Remove Media Converter Slide-in-Module protective plate
from selected installation slot by removing two screws that secure
plate to front of E-MCC-1600. Retain one installation screw.
3. Carefully slide Media Converter Slide-in-Module into installation slot, aligning
Media Converter Slide-in-Module with installation guides.NOTE: Ensure that the
Media Converter Slide-in-Module is firmly seated against the backplane.
4. Secure Slide-in-Module by installing retained installation screw.
C/E-100BTX-SX-01
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 full-duplex 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.
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 for four-position switch settings.
MDI/MDI-X Straight-Through/Crossover Straight-through/crossover 100BASE-TX requirements are
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.
