4.7 Ethernet Ports

4.7.1 RJ45 Twisted-Pair Data Ports

RS2000 series Ethernet switches are equipped with at least 24 10/100BaseTX ports that allow

connection to standard CAT-5 UTP cable with RJ45 male connectors. All RS2000 series RJ45

RuggedSwitch products feature auto-negotiation, auto-polarity, and auto-crossover functions. The

RJ45 receptacles can also accept and take advantage of screened (commonly known as

“shielded”) cabling. Figure 24 shows the RJ45 port pins configuration.

4.7.2 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 category 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 that characterizes

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. Table 6 summarizes cabling standards available today
