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.
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.
