C/E-CX-FRL-04

Provides a coax connector to 10BASE-2
coaxial “thin-net” Ethernet™ cable and a
set of RX (receive) and TX (transmit) ST
10BASE-FL connectors to 850nm
multimode fiber cable.

A Coax configuration switch sets an internal 10BASE-2 terminator
to EITHER 50 ohms OR 0 ohms.

• 0 ohm switch position is used when connecting to the
middle or in line of a thin coax segment.

• 50 ohm switch positionis used when connecting end of
coax segment DIRECTLY to the media converter's BNC
port.

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 [phone]/ (800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the 10BASE-2 link able to receive signals?

NO

• Check coax cables for proper connection.

• Check coax cable for opens or shorts. Check and/or replace each BNC “T” connector
on the segment, making sure each “T” is attached firmly.

• Verify that coax cables on media converter are terminated properly at both ends.
NOTE: In a coax thinnet installation, the first and last device in a daisy-chain are
terminated.

• Verify that each 10BASE-2 segment is grounded to earth ground.

• Contact Technical Support at [phone]/ (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 10BASE-FL device.

• Contact Technical Support at [phone]/ (800) LAN-WANS.

YES

• Contact Technical Support at [phone]/ (800) LAN-WANS.

Troubleshooting

Installing Slide-In-Module(s)

The physical characteristics of the media cable must meet or exceed IEEE

802.3 10BASE-2 and 10BASE-FL specifications.

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.

10BASE-2 CABLE CONNECTIONS

• Ground EACH coax segment to earth ground at one end.

• Set coax configuration switch:
Use 50 ohm switch position when connecting the end of a coax segment

DIRECTLY to the media converter's BNC port.
Use 0 ohm switch position when connecting to the middle or in line of a

thin coax segment. (For this position a BNC "T" must be connected to the
media converter's BNC port).

10BASE-FL CABLE CONNECTIONS

• Verify that the fiber products to be connected are 10BASE-FL or FOIRL
compliant. NOTE: Fiber ports on TRANSITION Networks fiber media
converters conform to 10BASE-FL or FOIRL but NOT to 10BaseFB or FDDI.
