Up-link Port 1X

Magnum DS8016s each have one Up-link port, port # 1X, which can be used

when port #1 is not connected. The Up-link port allows repeater-to-repeater connections

without a special cross-over cable. It works the same for 10Mb or 100Mb connections.

Use port “1” (or ports 2 thru 16) for straight-through twisted pair cabling from

the DS8016 port to a user device, or the “1X” port for cross-over or up-link segment

connections from the first DS8016 port to a repeater or hub or switch. Verify proper port

connection by noting the port’s LINK/RX status, which is illuminated when a proper link

is made and blinking when there is activity.

Note: Port # 1 and Port # 1X, provided for RJ45 connections, are logically one port.

Only one of these ports, either # 1 or # 1X may be used at one time simultaneously.
