6.3 Cabling installation, maintenance and safety
tips
The following is a list of important safety considerations that should be reviewed
prior to installing or maintaining your cables:
• Keep all UTP runs to a maximum of 100 feet each.
• Maintain the twists of the pairs all the way to the point of termination, or no
more that one-half inch untwisted. Do not skin off more than one inch of
jacket while terminating.
• If bending the cable is necessary, make it gradual with no bend sharper than
a one inch radius. Allowing the cable to be sharply bent or kinked can
permanently damage the cable's interior.
• Dress the cables neatly with cable ties, using low to moderate pressure. Do
not over tighten the ties.
• Cross-connect cables where necessary, using rated punch blocks, patch
panels and components. Do not splice or bridge the cable at any point.
• Keep the UTP cable as far away as possible from potential sources of EMI,
such as electrical cables, transformers and light fixtures. Do not tie the cables
to electrical conduits or lay the cables on electrical fixtures.
• Always test every installed segment with a cable tester. "Toning" alone is not
an acceptable test.
• 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.
