1.5
Cabling Recommendations
Before connecting the device, be aware of the recommendations and considerations
outlined in this section.
1.5.1
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 electri-
cal event, communications errors or interruptions may occur, but recovery is auto-
matic.
Siemens also does not recommend using copper Ethernet ports to interface with de-
vices 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.
1.5.2
Gigabit Ethernet 1000Base-TX Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbit/s Ethernet commu-
nications 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 de-
signers 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.
The following table summarizes the relevant cabling standards:
