UTP Cabling

This appendix discusses various aspects of connection media. The performance
of a s3-0801/1601 switching system depends on high quality connections. Poor
quality or poorly installed or maintained cabling can diminish switching system
performance. Switching systems utilize UTP cabling.
This appendix is for information purposes only. Please consult with your local code
officials and/or cabling consultants prior to any installation.
6.1

UTP copper cabling

The following are basic definitions for the three types of UTP cabling that the
switch supports:
• UTP (4-pair) high performance cable consists of twisted pair conductors,
used primarily for data transmission. The twisting of the pairs gives this cable
some immunity from the infiltration of unwanted interference. UTP cable is
generally used for networks running at 10 or 100 Mbps.
• CAT 5E (enhanced) cable has the same characteristics as CAT 5, but is
manufactured to somewhat more stringent standards.
• CAT 6 cable is manufactured to tighter requirements than CAT 5E cable.
CAT 6 has higher measured frequency ranges and significantly better
performance requirements than CAT 5E cable at the same frequencies.
6.2

Wiring 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. 6.2 describes the standards for each
pin.
