AX Series CAT5e wire Installation Do's and Don'ts
Do Run all cables in a "Star" configuration. That is to say that they all emanate from and are "homerun" to,
one central location, where the AX-CEU will be installed. Visualize a wagon wheel. All of the spokes
start from one central point.
Do Keep all cable runs to a maximum of 980 feet (for each run). IMPORTANT! This is an AX Series
specific distance.
Do Maintain the twists of the pairs all the way to the point of termination, or no more than 1/2" untwisted.
Do Not Skin off more than 1" of jacket when terminating.
Do Make gradual bends of the cable where necessary. No sharper than a 1" radius.
Do Not Allow the cable to be sharply bent or kinked at any time. This can cause permanent damage to the
cables' interior.
Do Dress the cables neatly with cable ties. Use low to moderate pressure.
Do Not Over tighten cable ties. Hook or Loop (Velcro) Cable Ties work very well for commercial installations.
Do Cross-connect cables (where necessary) using CAT5e rated punch blocks and components.
Do Not Splice or bridge CAT5e cable at any point. There should never be multiple appearances of CAT5e
cable.
Do Use low to moderate force when pulling cable.
Do Not Use excessive force when pulling cable.
Do Use cable pulling lubricant for cable runs that may otherwise require great force to install.
Do Not Use oil or any other lubricant not specifically designed for cable pulling. Oil or other lubricants, can
infiltrate the cable, causing damage to the installation.
Do Keep CAT5e cables as far away from potential sources of EMI (electrical cables, transformers, light
fixtures, etc.) as possible.
Do Not Tie cables to electrical conduits or lay cables on electrical fixures.
Do Install proper cable supports, spaced no more than 5 feet apart.
Do Not Install cable that is supported by the ceiling tiles (this is unsafe and may be a violation of building
codes).
Do Always label every termination point. Use a unique number for each cable segment.
Do Always test every installed segment with a cable tester. "Toning" alone is not an acceptable test.
Do Always install jacks in such a way as to prevent dust and other contaminants from settling on the
contacts. The contacts (pins) of the jack should face up on flush mount plates or left, right. or down
(never up) on surface mount boxes.
Do Always leave extra slack on the cables, neatly coiled up in the ceiling or nearest concealed place. it is
recommended that you leave at least 5 feet at the door station side and 10 feet at the CEU side.
Do Not Install cables "taught" in the ceiling or elsewhere. A good installation should have the cables loose but
never sagging.
Do Always use grommets to protect the cable where passing through metal studs or anything that can
possibly cause damage to them.
Do Configure the RJ45 jacks in the 568B wiring standard. 568B standard is required for the AX system.
Do Not Use the 568A wiring standard for the AX system.
Do Not Use staples on CAT5e cable that crimp the cable tightly. The common T-18 and T-25 cable staples are
(1 Exception) not recommended for CAT5e cable. The T-59 insulated staple gun is ideal for fastening CAT5e cabling
as it does not put any excess pressure on the cable.
Do Always obey all local and national fire and building codes. Be sure to "firestop" all cables that
penetrate a firewall. Use plenum rated cable where it is mandated.
