Set the Jumpers
Both jumpers are located on the media converter circuit board.
Enable/Disable AutoCross™
The AutoCross jumper is labeled “ J2 ”. The drawing illustrates the two
settings:
Disable Either straight-through or crossover twisted-
pair copper cable must be installed,
according to the site requirements
Enable The media converter connects automatically
to either straight-through or crossover
twisted-pair copper cable (see page 9).
NOTE: Factory default is “enable AutoCross.” Transition networks
recommends leaving the deivce in the “enable” mode.
Hardware/Software Mode
The Hardware/Software mode jumper is labeled “ J6 ”. The drawing illustrates
the two settings:
Hardware The media converter mode is determined by
the 4-position switch settings (see the “4-
Position switch” section on page 3).
Software The media converter mode is determined by
the most-recently saved, on-board
microprocessor settings.
Setting the Jumpers
To set the jumpers on the CRMFE10xx-20x , use small needle-nosed pliers or
similar device to move the jumper to the desired position.
To set the jumpers on the SRMFE10xx-20x :
1. Using a small screwdriver, remove the four (4) screws that secure the
cover to the media converter.
2. Carefully remove the cover from the media converter and locate the
jumper on the circuit board.
3. Using small needle-nosed pliers or similar device, move the jumper to
the desired position.
4. Carefully replace the cover on the media converter and replace the four

Install the CRMFE10xx-20x 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 CRMFE10xx-20x 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.

Install the Copper Cable
1. Locate or build 100Base-TX compliant copper 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
CRMFE10xx-20x (local) media converter.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45
port on the other (local) device (switch, workstation, etc.).
4. Repeat steps 2 and 3 for the SRMFE10xx-20x (remote) media converter.
5. Connect the RJ-45 connector at the other end of the cable to the RJ-45
port on the other (remote) device (switch, workstation, etc.).
