Install the Slide-In-Module
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when installing the media converter. Failure to observe this
caution could result in damage to, and subsequent failure of, the media
converter.
To install the CSETF10xx-205 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
module with the installation guides.
3. Ensure that the module is firmly seated inside the chassis.
4. Push in and rotate the attached panel fastener screw clockwise to secure
the module to the chassis front.

Installation
Set the Jumper
• The jumper is located on the circuit board.
• Use small needle-nose pliers to set the jumper.
Hardware The media converter settings such as
AutoCross and Link Pass-Through cannot be
changed.
Software The media converter settings are determined
by the most-recently saved, on-board
microprocessor settings.

Installing the Cable
Fiber
1. Locate or build 10/100Base-SX compliant fiber cable with male, twostranded TX to RX connectors installed at both ends.
2. Connect the fiber cables to the CSETF10xx-205 media converter as
described:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another media converter,
hub, etc.) as described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.
Connect the fiber cable
to the media converter

Product Features
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.

Auto-Negotiation
The Auto-Negotiation feature allows the 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 100Mb/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. No user intervention is required to
determine the best mode of operation.
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. (Note: Auto-
Negotiation can only be disabled in software mode.) 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 desired speed and duplex mode of
operation.
NOTE: The CSETF10xx-205 series media converter does not support rate
conversion between 10Mb/s and 100Mb/s network devices.
