Overview
This topic explains the NEBS statements for safety, spatial and environmental design that are applicable to the Cisco N916E-NS4-O switches.
NEBS describes the environment of a typical United States Regional Bell Operating Company (RBOC) central office. NEBS is the most common set of safety, spatial, and environmental design standards applied to telecommunications equipment in the United States. It is not a legal or regulatory requirement, but rather an industry requirement.
These NEBS statements apply to the Cisco N916E-NS4-O switches.
This equipment may be ESD sensitive. Always use an ESD ankle or wrist strap before handling equipment. Connect the equipment end of the ESD strap to an unfinished surface of the equipment chassis or to the ESD jack on the equipment if provided.
Statement 7003 —Shielded Cable Shielded Cable Requirements for Intrabuilding Lightning Surge
The intrabuilding port(s) of the equipment or subassembly must use shielded intrabuilding cabling/wiring that is grounded at both ends.
The following port(s) are considered intrabuilding ports on this equipment:
RJ-45 Management Ethernet Port
Statement 7004— Special Accessories Required to Comply with GR-1089 Emission and Immunity Requirements
To comply with the emission and immunity requirements of GR-1089, shielded cables are required for the following ports:
Copper RJ-45 Ethernet Management port
Statement 7005—Intrabuilding Lightning Surge and AC Power Fault
The intrabuilding port(s) 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 intrabuilding 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 to connect these interfaces metallically to OSP wiring.
This statement applies to the intrabuilding ports listed below:
RJ-45 Ethernet Management port
Connect this equipment to AC mains that are provided with a surge protective device (SPD) at the service equipment that complies with NFPA 70, the National Electrical Code (NEC).
This equipment is suitable for installations using the CBN.
When you use thread-forming screws to bond equipment to its mounting metalwork, remove any paint and nonconductive coatings and clean the joining surfaces. Apply an antioxidant compound before joining the surfaces between the equipment and mounting metalwork.
Statement 7016 —Battery Return Conductor
Treat the battery return conductor of this equipment as DC-I.
The equipment is designed to boot up in less than 30 minutes provided the neighboring devices are fully operational.
This equipment is suitable for installation in network telecommunications facilities.
This equipment is suitable for installation in locations where the NEC applies.
