Installation
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the 4-position switch and jumper. Failure to observe
this caution could result in damage to the media converter.
4-Position Switch
The 4-position switch is located on
the side of the media converter. Use
a small flat-blade screwdriver or a
similar device to set the switches
(see the drawing to the right).
1. Auto-Negotiation
up = Advertises 100Mb/s full-duplex and half-duplex.
down = Disables Auto-Negotiation. The media converter operates at 100
Mb/s in duplex mode (full or half) of the attached device. (This
setting is primarily used when connecting to a hub).
2. Pause Control Frame
(Applies only if switch 1 is up and the media converter is connected to AutoNegotiation device(s) capable of Pause Control Frame.)
up = Enabled
down = Disabled
3. Link Pass-Through
up = Enabled
down = Disabled
4. Far-End Fault
up = Enabled
down = Disabled.
AutoCross™ Jumper
The AutoCross feature allows either straight-through (MDI) or crossover
(MDI-X) cables to be used when connecting to devices such as hubs,
transceivers, or network interface cards (NICs). AutoCross determines the
characteristics of the cable connection and automatically configures the
media converter to link up, regardless of the cable configuration.
The jumper is located on the circuit board, header J3. To set the jumper:
1. Using a small screwdriver, remove the four (4)
screws securing the device cover, then remove it.
2. Locate the jumper on header J3. Use a small
needle-nosed pliers to move the jumper to the
desired position (see the drawing to the right).
3. Carefully replace the cover; then replace the four
(4) screws to secure the cover to the media
converter.

Installation -- continued
Connect the fiber cable
1. Locate a 100Base-FX compliant fiber cable with male, single-stranded
simplex connectors installed at both ends.
2. Connect the simplex connector at one end of the cable to the singlestrand fiber port on the first E-100BTX-FX-05(10x) media converter.
3. Connect the simplex connector at the other end of the cable to the singlestrand fiber port on the second E-100BTX-FX-05(10x) media converter.
Connect the twisted-pair copper cable
1. Locate or build 100Base-TX compliant cables, with male RJ-45
connectors installed at both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on
the E-100BTX-FX-05(10x) media converter.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45
port on the other E-100BTX-FX-05(10x) media converter.
Connect the fiber cable

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.

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).
