Installation Troubleshooting
To test the PSE-McBasic 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 whose features cannot be disabled, both twisted pair and
fiber cables must be connected before the link LEDs will light.
To test a PSE-McBasic by itself, first verify that an appropriate fiber patch cable is
being used. Then, follow these steps:
Step 1: Connect the PSE-McBasic 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 PSE-McBasic.
Step 3: Verify that the twisted pair port and fiber port link.
Use the appropriate twisted pair cable, and have the crossover/pass-through switch
set correctly.
If using a high powered device designed for long distance installations in a short
distance installation, an optical attenuator may be needed to prevent data loss on a
connection.
