Cables, Port Connections, and Pinout Information

This section explains the switch physical interfaces, and provides information about cables and port connections. Copper cable diagnostics are supported. High-speed workstations, hubs, routers, or other switches are connected through standard RJ-45 connectors to the switch physical interface ports, located on the front panel. For each device, the supported mode is set to Half Duplex, Full Duplex, and Auto.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections also operate with 1000BASE-T, provided if all four wire pairs are connected. However, it is recommended that enhanced Category 5 (Category 5e)cable is used for all critical connections or any new cable installations. The Category 5e specification includes test parameters that are only recommendations for Category 5, and comply with the IEEE 802.3ab standards.

RJ-45 Connections for 10/100/1000BASE-T Ports

The 10/100/1000BASE-T ports are copper Twisted-Pair ports.
