CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the jumper. Failure to observe this caution could result
in damage to, and subsequent failure of, the media converter.
Set the Coax Grounding Jumpers
NOTE: Modify the settings for J11 and J12 only if necessary.
Jumpers 11 and 12 (located on the circuit board near the coax ports) provide a
grounding feature so that the SCSCF30xx-10x media converter complies with
the G.703 specification where:
• The output coax port is connected to chassis ground.
• A provision to connect the input coax port to chassis ground is provided.
The factory settings for these two jumpers are:
Jumper 12 (jumpered) = Output coax port is connected to chassis ground.
Jumper 11 (not-jumpered) = Input coax port is not connected to chassis ground.
not jumpered
The jumpers are located on the circuit board inside the media converter
housing. To set the jumpers:
1. Using a small screwdriver, remove the four (4) screws that secure the cover
and carefully remove the cover from the media converter.
2. Locate the jumper on the circuit board.
3. Using small needle-nosed pliers or similar device, move the jumper to the
desired position. (Refer to the above drawing.)
4. Carefully replace the cover on the media converter and replace the four (4)
screws that secure the cover to the media converter.

Install the Coax Cable
1. Locate or build coax cables with female connectors installed at both
ends.
2. Connect the coax cables to the media converter as described:
• Connect the female TX cable connector to the male TX port.
• Connect the female RX cable connector to the male RX port.
3. Connect the coax cables to the other device (switch, workstation, etc.) as
described:
• Connect the female TX cable connector to the male RX port.
• Connect the female RX cable connector to the male TX port.

Install the Fiber Cable
1. Locate or build fiber cables with male, two-stranded TX to RX connectors
installed at both ends.
2. Connect the fiber cables to the local SCSCF30xx-10x 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 remote SCSCF30xx-10x media converter
as described:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.
