After you pull the cable along the route you selected earlier, bring it into the classroom. (Note: A future lesson will go into more details regarding some of the techniques used to route cable along walls, inside walls, inside attics, and behind drop ceilings.) Allow enough cable for the ends to reach all the way to each jack location, plus enough excess or slack to reach the floor and extend another 50-90 cm. Go back to the spools of cable at the central point or wiring closet. Use the labels on each spool as a reference, then mark each cable with the appropriate room number and letter. Do not cut the cables unless they have a label. For best results, cut the cable and the pull string with wire snips. This will produce a clean cut that will not result in loss of signal. If you follow each of these steps, the networking media used for the horizontal cabling run should be labeled at both ends.
