14Es feature an up-link switch on the RJ-45 port to eliminate the need for a special cross-over
cable when connecting the Copper port to a switch or hub. Because of their compact size,
Magnum 14Es can be Velcro®-mounted on an office wall or the side of a desk or cabinet.

3.6.3 Segment Distances, Half-duplex mode
Fast Ethernet shared bandwidth devices operate with multiple nodes in a traffic
domain. When a node attempts to send a packet, it may hit another packet passing by, i.e., a

into the RJ-45 connector of the Magnum 14E Media Converter.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED ensure proper connectivity by noting that the LED will be

4.3 Manual AN / reg Switch, auto-negotiation support
Magnum 14E and 14EH Media Converters are equipped with a tiny manual switch
(AN/reg), which controls the RJ-45 port only, located just beneath the up-link. See diagram.

The difference in the two AN/reg switch settings is for the attached port, i.e., the
port in the switch or hub or NIC at the other end of the twisted pair cable. If the attached
port is of the popular auto-negotiate-only variety, it needs to get FLPs from the 14E Media
