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 Link 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 Link 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-FX device.
• Refer to Tech Tips available at: http://www.transition.com
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES • Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
Troubleshooting
The physical characteristics of the media cable must meet or exceed IEEE
802.3u 100BASE-TX and 100BASE-FX 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: Media Converter Slide-in-Modules can be installed in any installation slot, in any
order.
To install the Media Converter Slide-in-Module in the E-MCC-1600 chassis:
1. 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.
2. 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.
3. Secure Slide-in-Module by installing retained installation screw.

100BASE-FX CABLE CONNECTIONS

• Be certain that the correct mode and wavelength fiber cable is used for single-
mode and/or for multimode fiber cable installations.

100BASE-TX CABLE CONNECTIONS

• Be certain that the MDI/MDI-X switch located ONthe Slide-In-Module circuit
board is set correctly before installing Slide-In-Module in Media Conversion
Center. Cable connections between a hub and the media converter require the
MDI/MDI-X switch to be set to MDI. 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,
set MDI/MDI-X switch
position for site installation.
