CHAPTER 3: Configuration

installed settings, JP1 links RJ-45 Pin 3 to the coax TX shield, while JP2 links RJ-45 Pin 6 to the coax RX shield.

To remove these jumpers in order to break these links, you’ll need to open the case of your Adapter or temporarily remove each port-card module from your Balun Mate II. Follow these steps, taking all reasonable precautions against static electricity:

1.Make sure that the Adapter or module is disconnected from all cables and from all other devices.

2A. If you’re setting the jumpers on an Adapter, insert a flat- blade screwdriver into the slot on the side of the Adapter’s case and twist. The case will pop open, exposing the circuit board.

2B. If you’re setting the jumpers on a Balun Mate II module, unscrew the nuts and washers on the module from the two screwposts embedded in the chassis’ front panel. (You might need a nutdriver to do this.)

Once this is done, carefully slide the module out of the back of the rack chassis.
