Decommissioning and Disposal

Proper decommissioning and disposal of this device is important to prevent malicious
users from obtaining proprietary information and to protect the environment.
Decommissioning
This device may include sensitive, proprietary data. Before taking the device out of
service, either permanently or for maintenance by a third-party, make sure it has
been fully decommissioned.
For more information, refer to the associated Configuration Manual.
Recycling and Disposal
For environmentally friendly recycling and disposal of this device and related acces-
sories, contact a facility certified to dispose of waste electrical and electronic equip-
ment. Recycling and disposal must be done in accordance with local regulations.

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.
