NEBS GR-1089 Installation and Caution Instructions
The following are NEBS GR-1089 installation and caution instructions.
Caution
The intra-building ports (Ethernet and serial) of the equipment or subassembly is suitable for connection
to intra-building or unexposed wiring or cabling only. The intra-building ports of the equipment or
subassembly must not be metallically connected to interfaces that connect to the outside plant (OSP) or
its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports
as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of
primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP
wiring.

•
An electrical conducting path shall exist between the product chassis and the metal surface of the
enclosure or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be
provided by using thread-forming type mounting screws that remove any paint or nonconductive
coatings and establish a metal-to-metal contact. Any paint or other nonconductive coatings shall be
removed on the surfaces between the mounting hardware and the enclosure or rack. The surfaces
shall be cleaned and an antioxidant applied before installation.
