3.7. Copper Ethernet Ports

The RuggedBackbone™ RX1501 can be ordered with up to 36 10/100Base-TX ports that allow connection to standard CAT-5 UTP cable with RJ45 male connectors. All copper Ethernet ports feature auto-negotiation, auto-polarity, and auto-crossover functions. The female RJ45 connector can accept and take advantage of screened (commonly known as “shielded”) cabling.

3.7.1. RJ45 Twisted-Pair Copper Ports

Female RJ45 connectors are available on LMs that support 10/100Base-T and on LMs and SMs that support 10/100/1000Base-T Ethernet. See the illustration and table below for pin configuration and assignment.

3.7.2. Gigabit Ethernet 1000Base-TX Cabling Recommendations

The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet communications over distances of up to 100 meters using 4 pairs of CAT-5 (or higher) balanced, unshielded twisted-pair cabling. For wiring guidelines, system designers and integrators should refer to the Telecommunications Industry Association (TIA) TIA/EIA-568-A wiring standard for minimum cabling performance specifications required for proper Gigabit Ethernet operation. To ensure reliable, error-free data communications, new and pre-existing communication paths should be verified for TIA/EIA-568-A compliance. The table: Cabling Categories and 1000Base- TX Compliance summarizes the relevant cabling standards as they apply to 100Base-TX connections.
