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.
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 need to be
added to the connection.
