APPENDIX C: CABLING GUIDELINES

This appendix provides specifications for cables used with the NETGEAR Model

GS524T Copper Gigabit Switch.

Using 1000BASE-T Gigabit Ethernet over Category 5 Cable

Overview

When using the 1000BASE-T standard, the limitations of cable installations and

the steps necessary to ensure optimum performance must be considered.The most

important components in your cabling system are patch panel connections,twists

of the pairs at connector transition points, the jacket around the twisted pair cable,

bundling of multiple pairs on horizontal runs and punch down blocks.All of these

will affect the performance of 1000BASE-T technology if not correctly imple-

mented.The following sections are designed to act as a guide to correct cabling for

1000BASE-T.

Cabling

The 1000BASE-T product is designed to operate over Category 5 cabling, but to

further enhance the operation, the cabling standards have been amended.The latest

standard is Category 5e,which defines a higher level of link performance than is

available with Category 5 cable.

If installing new cable,we recommend using Category 5e cable,since it costs about

the same as Category 5 cable and will increase performance. If using the existing

cable,be sure to have the cable plant tested by a professional who can verify that

it meets or exceeds either ANSI/EIA/TIA-568-A:1995 or ISO/IEC 11801:1995

Category 5 specifications.

Length

The maximum distance limitation between two pieces of equipment is 100 m,as

per the original Ethernet specification.The end to end link is called the “channel.”

TSB-67 defines the “Basic Link”which is the portion of the link that is part of the

building infrastructure.This excludes patch and equipment cords.The maximum

basic link length is 295 feet (90 m).
