The two active pairs in an
ATM network are pins 1 & 2
and pins 7 & 8. Use only
dedicated wire pairs (such as
blue/white & white/blue,
orange/white & white/orange)
for the active pins.
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 Copper Activity 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 Activity 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.

Be certain that the twisted-pair cable is configured correctly (straight through
or crossover) for site. Cable connections between an ATM switch and the
media converter must be configured as straight through. Cable connections
between the media converter and a NIC must be configured as crossover.
The physical characteristics of the media cable must meet or exceed the
specifications: ATM UNI 3.1 #AF-PHY-0015
Maximum number of media converters in series:
2

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-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 seated firmly against the
backplane.
3. Secure Slide-in-Module by installing retained installation screw.
