equipment (on a rack) and then a single ground conductor can be routed from the same block to
an approved ground.
Danger:
Failure to install both grounds will void the Product Safety certifications (UL and the CE Mark)
on the product, as well as allow a hazard to be present that could result in death or severe
personal injury.

Approved grounds
There are two methods for equipment grounding.
The first is based on NFPA 70: National Electrical Code (NEC – a United States code).
Note:
Compliance with NFPA 70: NEC – or – with the equivalent local electrical code/grounding
requirements is mandatory.
The second is based on ANSI/EIA/TIA-607 (Commercial Building Grounding (Earthing) and
Bonding Requirements for Telecommunications).
Note:
ANSI/EIA/TIA-607 (TIA-607) defines an intra-building ground-wiring scheme for
communications equipment, and specifies equipment connection/grounding points according
to that scheme. TIA-607 assumes the underlying building grounding infrastructure is in
compliance with NFPA 70: NEC. Compliance with the NEC (or the equivalent local electrical
code/grounding requirements) is essential for the proper application of TIA-607.
Compliance with NFPA 70: NEC will provide suitable grounding for the Avaya equipment. TIA-607
provides an enhanced, communications-specific grounding scheme: where TIA-607 has been
implemented the Avaya equipment shall be grounded per this method.
Important:
• Ensure that the installation site has access to approved grounds and that either a trained
technician or a licensed electrician will be verifying all grounds and installing the
Supplementary Ground Conductor.
• If you have difficulty interpreting the grounding methods in this document, Avaya
recommends obtaining the services of a certified power contractor or auditor prior to
system installation or cutover.
Warning:
Failure to follow grounding recommendations can result is a system installation that is:
• Unsafe for personnel handling or using the equipment
• Not properly protected from lightning or power transients
