Powering the media converter
AC
1.
Install the power cord barrel connector into the back of the media
converter.
2.
Connect the power adapter plug into AC power.
3.
Verify that the media converter is powered by observing the illuminated
LED power indicator light.
DC
Consult user guide 33266 for information on the SPS-1872-xx DC external
power supply.
Operation
Status LEDs
The E-100BTX-FX-05(10x) media converter is designed to operate without
user intervention. Use the status LEDs to monitor media-converter operation
on the network.

Product features
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to perform
automatic configuration to achieve the best possible mode of operation over a
link. The media converter will broadcast its speed
(10 Mb/s, 100 Mb/s, etc.)
and duplex
(full/half)
capabilities to the other devices and negotiate the best
mode of operation.
NOTE:
The E-100BTX-FX-05(10x) series media converter does NOT support
rate conversion between 10Mb/s, 100Mb/s, and 1000Mb/s network devices.
Pause Control Frame
The Pause Control Frame feature can improve network performance by
allowing one end of the link to signal the other to discontinue frame
transmission for a set period of time to relieve buffer congestion.
NOTE:
If the Pause Control feature is present on ALL network devices
attached to the media converter(s), enable the Pause Control feature on the
media converter(s). Otherwise, disable Pause Control.
Link Pass-Through
The Link Pass-Through feature 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, the media converter will automatically disable the TX
(transmit)
signal, thus, “passing through” the link loss. The far-end device is notified
automatically of the link loss, which prevents the loss of valuable data
unknowingly transmitted over an invalid link.
Far-End Fault
When a fault occurs on an incoming fiber link (1), the media converter
transmits a Far-End Fault signal on the outgoing fiber link (2). In addition, the
Far-End Fault signal also activates Link Pass-Through, which in turn disables
the link on the copper portion of the network (3) and (4).
