Switch Settings and Cable Requirements
Station: Selected when connecting
media converter to terminal device.
Lobe:
Selected when connecting
media converter to switch.
1. Is the power LED on the media converter illuminated?
NO
•
Is the power adapter the proper type of voltage and cycle frequency for AC outlet?
•
Is the power adapter properly installed in the media converter and in the outlet?
•
Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
•
Proceed to step 2.
2. Is the Copper SDC Link LED illuminated?
NO
•
Check UTP cables for proper connection and switch position. (See above.)
•
Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES

Twisted pair connection requires two active pairs
configured as straight through. The two active
pairs in a Token Ring network are pins 4 & 5 and
pins 3 & 6. Use only dedicated wire pairs (such
