• Always install jacks so as to prevent dust and other contaminants
from settling on the contacts. The contacts of the jack should face
up on the flush mounted plates, or left/right/down on surface
mount boxes.
• Always leave extra slack on the cables, neatly coiled in the
ceiling or nearest concealed location. Leave at least five feet at
the work outlet side and 15 feet at the patch panel side.
• Choose either 568A or 568B wiring standard before beginning.
Wire all jacks and patch panels for the same wiring scheme. Do
not mix 568A and 568B wiring in the same installation.
• Always obey all local and national fire and building codes. Be
sure to firestop all the cables that penetrate a firewall. Use
plenum-rated cable where it is required.
