FAULT ISOLATION and CORRECTION

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 Power LED on the media converter illuminated?

• Is the power adapter the proper voltage and cycle frequency for the

AC outlet?

NOTE: Refer to the “Power Supply Requirements” on page 7.

• Is the power adapter properly installed in the media converter and

in the outlet?

• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the SDFiber (Signal Detect/Fiber) LED illuminated?

• Check fiber cables for proper connection.

• Verify that TX and RX cables on media converter are connected to

RX and TX ports, respectively, on other media converter.

• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.

YES

• Proceed to step 3.

3. Is the SDTP (Signal Detect/Twisted-Pair) LED illuminated?

• Check twisted pair cables for proper connection.

• Check RJ-45 Pinning Switch for correct twisted pair cable

configuration.

• Check integrity of device attached to media converter by twisted-

pair cable.

• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.

YES

• Proceed to step 4.

4. Is the AISFiber LED on either media converter illuminated?

• Proceed to step 5.

YES

• Determine if broken fiber link has caused All Ones Insertion (AIS)

on the fiber interface and correct failure. If not, proceed to step 5.

Set switches 5, 6, and 7 to

enable test functions or to

permit normal network

operation. (Switch 8 not used.)

Set the MDI/MDI-X switch to use straight-through cable where crossover-

configuration cable is required.
