Power the Media Converter
The CBFTF10xx-10x slide-in-module media converter is powered through the
Point System™ chassis.
Operation
Status LEDs
Use the status LEDs to monitor the media
converter and the network connections.
The “FD” and “LACT” LEDs near the top of the
media converter refer to the
fiber port
.
F(ull) D(uplex)
On = Full-duplex fiber connection.
Off = Half-duplex fiber connection.
L(ink) ACT(ivity)
On = Fiber link connection.
Flashing = Fiber network activity.
P(o)W(e)R
On = Connection to external AC or DC power.
The two-color LEDs refer to the
twisted-pair copper port
.
Duplex/Link LED
Yellow = A link on the half-duplex twisted-pair copper link.
Flashing Yellow = Activity on the half-duplex copper link.
Green = A link on the full-duplex twisted-pair copper link.
Flashing Green = Activity on the full-duplex copper link.
Speed LED
Yellow = 10 Mb/s operation.
Green = 100 Mb/s operation.

Product Features
Rate Conversion
The media converter allows connection of
10Mb/s
terminal devices on a
10Base-T legacy Ethernet copper network to
100Mb/s
terminal devices on a
100Base-TX fast Ethernet copper network.
Auto-Negotiation
The Auto-Negotiation feature allows the CBFTF10xx-10x media converter to
automatically configure itself to achieve the best possible mode of operation
over a link. The media converter broadcasts its speed (10 Mb/s or 100 Mb/s)
and duplex capabilities (full or half) to the other devices and negotiates the
best mode of operation. Auto-Negotiation allows quick and easy installation
because the optimal link is established automatically.
A scenario where the media converter is linked to a non-negotiating device is
a case where the user may want to
disable
Auto-Negotiation. In this instance,
the mode of operation will drop to the least common denominator between
the two devices (e.g.: 10 Mb/s, half-duplex). Disabling this feature gives the
user the ability to force the connection to the best mode of operation.
AutoCross™
When the AutoCross feature is activated, it allows either straight-through
(MDI) or crossover (MDI-X) copper cables to be used when connecting to
10Base-T or 100Base-TX devices. AutoCross determines the characteristics of
the connection and automatically configures the unit to link up, regardless if
the copper cable is MDI or MDI-X configuration. (Transition networks
recommends leaving the device in the default “enable” mode.)
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 (1), the media converter will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of
valuable data unknowingly transmitted over an invalid link.
