Installation -- Continued

Set the AutoCross™ Jumper

When the AutoCross feature is activated, it allows either straight-through or crossover cables to be used when connecting to 100Base-TX devices. AutoCross determines the characteristics of the connection and automatically configures the unit to link up, regardless of the cable configuration.

•The jumper is located on the circuit board labeled “D” and “E”.

•Use small needle-nose pliers to remove and position the jumper.

Troubleshooting

If the media converter fails, isolate and correct the failure by determining the answers to the following questions and then taking the indicated action:

1.	Is the PWR LED on the media converter illuminated?
	NO
	• Is the media converter installed properly in the chassis?
	• Is the power cord properly installed in the chassis and at the external
	power source?
	• Does the external power source provide power?
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).

Disable	Either straight-through or crossover
	twisted-pair copper cable must be
	installed, according to the site
	requirements.
Enable	The media converter connects
	automatically to either straight-through or
	crossover twisted-pair copper cable.

D E Disable AutoCross

D E Enable AutoCross

	YES
	• Proceed to step 2.
2.	Is the LKC LED on the media converter illuminated?
	NO
	• Check the twisted-pair cables for proper connection.
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).
	YES
	• Proceed to step 3.

NOTE: AutoCross is enabled by default.” Transition networks recommends leaving the jumper in the “enable” position.

Install the media converter

CAUTION: Wear a grounding device and observe electrostatic discharge precautions when installing the CFETF10xx-205 media converter. Failure to observe this caution could result in damage to or failure of, the media converter.

1.Carefully slide the media converter into the slot, aligning it with the slot guides.

2.Ensure that the converter is firmly seated into the slot.

3.Push in and rotate the attached panel fastener screw clockwise to secure the converter to the chassis.

3.	Is the LKF LED on the media converter illuminated?
	NO
	• Check the fiber cables for proper connection.
	• Verify that the TX and RX cables on the media converter are
	connected to the RX and TX ports, respectively, on the other device.
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).
	YES
	• Proceed to step 4.
4.	Is the RXC LED on the media converter flashing?
	NO
	• If there is no activity on the 100Base-TX port, proceed to step 5.
	• If there is activity on the 100Base-TX port, disconnect and reconnect
	the 100Base-TX cable to restart the initialization process.
	• Restart the workstation to restart the initialization process.
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).
	YES
	• Proceed to step 5.
5.	Is the RXF LED on the media converter flashing?
	NO
	• If there is activity on the 100Base-FX port, disconnect and reconnect
	the 100Base-FX cable to restart the initialization process.
	• Verify that the TX and RX cables on the media converter are
	connected to the RX and TX ports, respectively, on the other device.
	• Restart the workstation to restart the initialization process.
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).
	YES
	• Contact Technical Support: 1-800-260-1312 (Int’l: 00-1-952-7600).
