NEBS safety statements when using NEBS racks for mounting the switch.
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.
The following NEBS statements apply to the Cisco C9550 Series Smart Switches:
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
Statement 7009—Equipment With Integrated Primary Protection (EIPP)
This equipment contains integrated primary protection. This equipment is not suitable for installation in central office (CO) and network locations that contain other primary protection for outside plant (OSP) cables, such as electronic equipment enclosures (EEEs), for example, controlled environmental vaults (CEVs) and huts. The equipment may be located in electronic equipment cabinets (EECs) where appropriate installation practices are used, for example, installation should not employ a separate primary protector for the equipment, appropriate cabling should be run to the equipment, and so forth. For the purposes of determining placement and location of fuse links or fuse cable, treat the equipment as a fuseless protector regardless of any capability it has to provide fusing. This equipment utilizes a listed integral primary protector rated .
Statement 7013—Equipment Grounding Systems—Common Bonding Network (CBN)
This equipment is suitable for installations using the CBN.
Statement 7016—Battery Return Conductor
Treat the battery return conductor of this equipment as DC-I.
Statement 7018—System Recover Time
The equipment is designed to boot up in less than 30 minutes provided the neighboring devices are fully operational.
Statement 8015—Installation Location Network Telecommunications Facilities
This equipment is suitable for installation in network telecommunications facilities.
Statement 8016—Installation Location Where the National Electric Code (NEC) Applies
This equipment is suitable for installation in locations where the NEC applies.
