Best Practices Do’s and Don’ts:
Do
Keep all cable runs to a maximum of 135 foot for the Rx/ARA and 110 foot for the Tx/ATA.
Do
Maintain the twists of the pairs all the way to the point of termination, or no more than 0.5” (one half inch) untwisted.
Do
Make gradual bends of the cable, where necessary. No sharper than a 10" radius. About the size of a Volley ball.
Do
Not
Allow the cable to be sharply bent, or kinked, at any time.
Do
Dress the cables neatly with cable ties and trim excess from the cable tie. Use low to moderate pressure.
Do
Not
Over tighten cable ties.
Do
Not
Use excessive force when pulling cable.
Do
Not
Tie cables to electrical conduits, or lay cables on electrical fixtures, or have cables touch water pipes, or tie cables to
ceiling grid wire or threaded pipe supports, or touch ceiling tiles, or AC duct work.
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 is a violation of the building codes).
Do
Always label each cable correctly according to the floor plan. Use a unique number for each cable segment. The idea here,
is to make moves, adds, changes, and troubleshooting as simple as possible.
Do
Not
Never install cables taunt 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
Not
Use staples on cables.
Do
Always obey all local, and national, fire and building codes. Be sure to "fire stop" all cables that penetrate a firewall.
