APPENDIX C: CABLING GUIDELINES

This appendix provides specifications for cables used with the Model FS518T Fast

Ethernet Switch.

Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for

100BASE-TX.The specification requires Category 5 UTP cable consisting of either

two-pair or four-pair twisted insulated copper conductors bound in a single plastic

sheath. Category 5 cable is certified up to 100 MHz bandwidth. 100BASE-TX oper-

ation uses one pair of wires for transmission and the other pair for receiving and for

collision detection.

When installing Category 5 UTP cabling, use the following guidelines to ensure that

your cables perform to the following specifications:

• Certification

Make sure that your Category 5 UTP cable has completed the Underwriters

Laboratories (UL) or Electronic Testing Laboratories (ETL) certification process.

• Termination method

To minimize cross-talk noise, maintain the twist ratio of the cable up to the point

of termination; untwist at any RJ-45 plug or patch panel should not exceed

0.5 inch (1.5 cm).
