D. Cabling Guidelines

This appendix provides specifications for cables used with a NETGEAR Smart

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

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

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 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).
