Installation Troubleshooting

• During installation, first test the fiber and twisted pair connections with all

troubleshooting features disabled, then enable these features, if desired, just
before final installation. This will reduce the features’ interference with testing.

• When working with units where the features cannot be disabled, BOTH the

twisted pair and fiber connections must be established before the link LEDs will
light!

• To test a media converter by itself, have an appropriate fiber patch cable, then

follow these steps to test:

Step 1

Connect the media converter to the twisted pair device with a twisted
pair cable.

Step 2

Loop a single strand of fiber from the transmit port to the receive port of
the media converter.

Step 3

Verify that both twisted pair and fiber link (see LED Operation) are on
the media converter.

• Make sure to use the appropriate twisted pair cable, and have the

crossover/pass-through switch set correctly, if the media converter does not
include AutoCross.

• If using a high powered device (which is designed for long distance installations)

for a short distance installation, the fiber transmitters may overdrive the receivers
and cause data loss. If this is the case, an optical attenuator may be need to be
added to the connection.
