Appendix E: UTP Cabling
This appendix discusses various aspects of connection media. The switch system utilizes UTP cabling. The
performance of the system depends on high quality connections. Poor quality or poorly installed or maintained
cabling can diminish switch system performance.
NOTE: This appendix is for information purposes only. Please consult with your local code officials and/or
cabling consultants prior to any installation.
UTP copper cabling
The following are basic definitions for the three types of UTP cabling that the switch supports.
• CAT 5 (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. CAT 5 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.
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 UTP cable specifications. The switch system supports
either of these wiring standards. The following table describes the standards for each pin.
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
