Protection On Twisted-Pair Data Ports

All copper Ethernet ports on RUGGEDCOM products include transient suppression circuitry to protect against
damage from electrical transients and conform with IEC 61850-3 and IEEE 1613 Class 1 standards. This means
that during a transient electrical event, communications errors or interruptions may occur, but recovery is
automatic.
Siemens also does not recommend using copper Ethernet ports to interface with devices in the field across
distances that could produce high levels of ground potential rise (i.e. greater than 2500 V), during line-to-ground
fault conditions.
Section 1.4.2

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 m (328 ft) using all 4 pairs in 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. For reliable, error-free data communication, new and pre-existing communication
paths should be verified for TIA/EIA-568-A compliance.
