Add Jacks to the Jack Field

To add jack boxes to the jack field, do the following:

1Position the jack panel box so that the door with the handle is on the right (as you face it), and attach it to the top box in the rightmost column of boxes already in the jack field by meshing the tongues and grooves.

2Use appropriate screws to attach the jack panel box to the mounting surface that supports the jack field.

3Pull the two plastic caps off the connecting block on the 4-line adapter, and set the caps aside. You’ll need the caps again in a later step.

4Snap the 4-line adapter into the jack panel box so that the jacks on the adapter face to the right. If you have more than four outside lines, remove the plastic caps from the other adapters and snap them into the box in the same way.

Connect the Outside Lines to the Jack Field

To connect outside lines to the jack field, do the following:

1Attach the connector on the 25-pair cable to the 50-pin connector at the network interface.

2Slit the jacket at the free end of the 25-pair cable, and cut away as much of the jacket as necessary to allow the individual twisted pairs of colored wires to reach the adapter(s) in the jack field.

3Following the order and color code, place the colored wires in the grooves on the block of the adapter. If you have more than four outside lines,

continue placing wires in grooves on the remaining adapters until you have attached a pair of wires for each outside line.

4Align the two plastic caps over the grooved block that holds the colored wires on the adapter, and push the caps down until they snap into place. If you have more than one adapter, do the same with each of them.

5If the caps did not trim the wires when you snapped them down onto the block, use a pair of scissors to trim the ends of the wire protruding from the grooves. When you’re finished, none of the wires should extend far enough beyond the plastic caps to touch each other.

Label the Jacks and the Jack Panel Box

You should have a label sheet that includes a telephone number directory, jack-identifier label strips, and labels for the jack panel box and the line jacks. To label the jacks in the box, do the following:

1On the telephone number directory, fill in the telephone numbers for your outside lines in the order in which they appear at the network interface or on the list provided by the local telephone company.

2Using the telephone number directory as a guide, label the jacks in the jack panel box with the appropriate line jack labels.

3Attach the label to the outside of the right door of the jack panel box.

4Attach the long, narrow label showing jacks 1 through 8 to the inside of the right door of the jack panel box.
