3.7. Copper Ethernet Ports
The RuggedBackbone™ RX1510 can be ordered with up to 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:
