1000BASE-T Cable Requirements Making Network Connections

Do not plug a phone jack connector into any RJ-45 port. This may damage the IBP. Instead, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

For 1000 Mbps operation, all four wire pairs in the cable must be connected. When auto-negotiation is enabled, the 1000BASE-T ports support the auto MDI/MDI-X feature, which means that at any operating speed (10, 100, or 1000 Mbps), either straight-through or crossover cables can be used to connect to any server, workstation, or other network device. Make sure each twisted-pair cable does not exceed

100 meters (328 feet). (Note that auto-negotiation must be enabled to support auto MDI/MDI-X.)

4.2 1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) cable should be used. The Category 5e specification includes test parameters that are only recommenda- tions for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3ab standards.

4.2.1Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing infor- mation is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95Bulletin, “The Additional Transmission Performance Guidelines for 100 Ohm 4- Pair Category 5 Cabling”.

Note that when testing your cable installation, be sure to include all patch cables between IBP and end devices.
