UTP cabling

The following information is intended to brief you on various aspects of connection
media. The performance of a switching system depends on high quality connections.
Poor quality or poorly installed or maintained cabling can diminish system
performance.This appendix is for information purposes only. Consult with the local code
officials or cabling consultants prior to any installation.
5.2.1

UTP copper cabling

Switching systems utilize unshielded twisted pair (UTP) cabling.The following are basic
definitions for the three types of UTP cabling that the appliance supports:
• Cat 5 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. Cat 5 cable is generally
used for networks running at 100 or 1000 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.
5.2.2

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 Cat5,
5E, and 6 cable specifications. The switching system supports either of these wiring
standards. Refer to the following table for details.
