SSEFE10xx-10x
24-Hour Technical Support: 1-800-260-1312 -- International: 00-1-952-941-7600
Installation
The Link Pass-Through and speed switches are located on the side of the
media converter. Use a small screwdriver to set the recessed switches.
Set Link Pass-Through (switch 1)
Switch 1 sets the Link Pass-Through feature:
up = Enable Link Pass-Through.
down = Disable Link Pass-Through.
Link Pass-Through is a troubleshooting feature that allows the media converter
to monitor both the fiber and copper RX (receive) ports for loss of signal. In
the event of a loss of an RX signal on one media port, the media converter will
automatically disable the TX (transmit) signal of the other media port, thus,
“passing through” the link loss. This feature prevents the loss of valuable data
unknowingly transmitted over an invalid link.
Speed: up = 100 Mb/s
Link Pass-Through: up = Enable

Set the Speed (switch 2)
Switch 2 sets the speed for both the twisted-pair copper and fiber links:
up = copper and fiber links are at 100Mb/s.
down = copper and fiber links are at 10 Mb/s.
NOTE: The SSEFE10xx-10x media converters are fully compliant with
10Base-T, 100Base-TX, and 100Base-FX standards and, therefore, can be
connected to any compliant 10Base-T, 100Base-TX, and 100Base-FX devices.
The SSEFE10xx-10x media converters are NOT 10Base-FL compliant and,
therefore, must be connected to another SSEFE10xx-10x media converter in a
10Mb/s network.
