Introduction
1.4Decommissioning and Disposal
1.4 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
accessories, contact a facility certified to dispose of waste electrical and electronic
equipment. Recycling and disposal must be done in accordance with local
regulations.
1.5 Cabling Recommendations
The IEEE 802.3ab Gigabit Ethernet standard defines 1000 Mbps 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.
The following table summarizes the relevant cabling standards:
Cabling
Category
1000Base-
TX Compliant
Required Action
< 5 No New wiring infrastructure required.
5 Yes Verify TIA/EIA-568-A compliance.
5e Yes No action required. New installations should be designed with
Category 5e or higher.
6 Yes No action required.
> 6 Yes Connector and wiring standards to be determined.
Follow these recommendations for copper data cabling in high electrical noise
environments:
• Data cable lengths should be as short as possible, preferably 3 m (10
ft) in length. Copper data cables should not be used for inter-building
communications.

Installation Manual, 04/2021, C79000-G8976-1172-07

Introduction
1.5Cabling Recommendations
• Power and data cables should not be run in parallel for long distances, and
should be installed in separate conduits. Power and data cables should intersect
at 90° angles when necessary to reduce inductive coupling.
• Shielded/screened cabling can be used when required. Care should be taken to
avoid the creation of ground loops with shielded cabling.
