Cabling Guidelines
This appendix provides specifications for cables used for the Model FS562/FS566 switch.
Fast Ethernet Cable Guidelines
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 2-pair or 4-pair twisted
insulated copper conductors bound in a single plastic sheath. Category 5 cable is certified up to
100 MHz bandwidth. 100BASE-TX operation 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 crosstalk 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).
