Now that you have the individual wires exposed and separated, snap them in the punchdown block grooves by hand, starting at the first slot, observing these 2 rules:
1) Keep the twists in the wire pairs up to within 1/2 inch from the grooves in the block, and
2) Remember the BL-O-G order as you put the wires in the slots: white-blue, blue, white-orange, orange, white-green, green, white-brown, and brown.
You can allow an inch or more of the wires to extend beyond the punchdown grooves. These will be cut off with the punchdown tool.
Here is a picture of the punchdown tool. It does two things: it forces the wire strand into the slot, and it cuts off the end.
One side of the blade is clearly labelled "CUT" or "CUTTER". This is the side you must have pointed toward the wire ends as you begin punching down the wires.
Once the wires are positioned and properly color-coded, you can begin punching them down with the punchdown tool.
Again, note the position of the word "CUT" on the tool, and the order of the wire strands: white-blue, blue, white-orange, orange, etc.
Note that as you punch down the wires they are neatly terminated at the block. The incoming cable extends from the other side of the block. Now we are ready to attach the connecting block and the outgoing cable.
