Wiring standards

5.3.2Wiring standards

There are two supported wiring standards for 8-conductor (4-pair) RJ-45 terminated UTP cable: EIA/TIA 568A and B. These standards apply to installations utilizing Cat 5, 5E, and 6 cable specifications. The switching system supports either of these wiring standards. Refer to the following table for details.

Pin	EIA/TIA 568A	EIA/TIA 568B
1	white/green	white/orange
2	green	orange
3	white/orange	white/green
4	blue	blue
5	white/blue	white/blue
6	orange	green
7	white/brown	white/brown
8	brown	brown

5.3.3Cabling installation, maintenance, and safety tips

The following is a list of important safety considerations that should be reviewed prior to installing or maintaining the cables:

•Keep all Cat 5 runs to a maximum of 10 meters 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. Sharply bending or kinking the cable can permanently damage the interior of the cable.

•Arrange the cables neatly with cable ties, using low to moderate pressure. Do not over tighten ties.

•Cross-connect cables where necessary, using rated punch blocks, patch panels, and components. Do not splice or bridge cables at any point.

•Keep the Cat 5 cable as far away as possible from potential sources of EMI, such as electrical cables, transformers, and light fixtures. Do not tie cables to electrical conduits or lay cables on electrical fixtures.

•Always test every installed segment with a cable tester. Toning alone is not an acceptable test.
