CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the 4-position switch and the jumper(s) and when
installing the Slide-in-Module. Failure to observe this caution could result in
damage to, and subsequent failure of, the Media Converter.
Set the 4-Position Switch
The 4-position switch is located on the
side of the Media Converter. Use a
small flatblade screwdriver or a similar
device to set the recessed switches.
Refer to the drawing for the locations
of the four individual switches.

Set the Jumpers
The jumpers are located on the Media Converter circuit board. Use small
needle-nosed pliers or a similar device to set the jumper.
The Hardware/Software jumper is labeled “H” for hardware and “S” for
software (see the drawing below).
Hardware The Media Converter mode is determined by
the 4-position switch settings listed above.
Software The Media Converter mode is determined by
the most-recently saved, on-board
microprocessor settings.
The Far-End Fault jumper is labeled “FE” for enable Far-End Fault and “FD”
for disable Far-End Fault (see the drawing below).
EnableA fault on the fiber link causes the Media
Converter to transmit a Far-End Fault signal.
DisableNo Far-End Fault signal is transmitted when a
fault occurs.
Installing the Slide-In-Module
CAUTION: Slots in the PointSystem™ Chassis without a Slide-in-Module
installed MUST have a protective plate covering the empty slot for Class A
and/or Class B compliance.
To install the CGETF10xx-15x Media Converter Slide-in-Module:
1.Locate an empty installation slot on the PointSystem™ Chassis.
2.Carefully slide the Slide-in-Module into the installation slot, aligning the
Slide-in-Module with the installation guides.
3.Ensure that the Slide-in-Module is firmly seated against the back of the
chassis.
4. Secure the Slide-in-Module by securing the panel fastener screw
(attached to the Slide-in-Module) to the chassis front.

Product Features
Auto-Negotiation
The Auto-Negotiation feature allows the Media Converter to be used with
10Base-T and 100Base-TX twisted-pair ports. Using Auto-Negotiation, the
Media Converter brings up the copper links in the highest speed and mode
possible for all the attached network devices.
If selected, Auto-Negotiation allows a twisted-pair link to become operational
only after the Auto-Negotiation function matches network speed capabilities
at both ends of the twisted-pair copper segment.
Autocross
The AutoCross™ feature, when selected, allows either straight-through (MDI)
or crossover (MDI-X) cables to be used when connecting to 10Base-TX or
100Base-TX devices, such as hubs, transceivers, or network interface cards
(NICs). AutoCross determines the characteristics of the cable connection and
automatically configures the unit to link up, regardless of the cable
configuration. (This feature does not require operator intervention.)
Far-End Fault
When the Far-End Fault feature is activated, a fault on an incoming fiber link
causes the Media Converter to transmit a Far-End Fault signal on the outgoing
fiber link. In addition the Far-End Fault signal also activates the Link PassThrough, which, in turn, disables the link on the copper portion of the
network.

Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See page 1 (front cover) for the cable specifications
for the different CBFTF10xx-15x models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex Network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A
collision domain is the longest path between any two terminal devices, e.g. a
terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled “Collision
