To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the serial high-speed WAN interface ports only to intra-building or unexposed wiring or
cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The
intra-building port(s) of the equipment or subassembly must not be metallically connected to
interfaces that connect to the 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. Statement 7003
Warning
The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building
or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly
MUST NOT metallically connect to interfaces that connect to the 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, Issue 5) 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. Statement 7018
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security. Statement 1072
Warning
Always use the ESD wristband when working. See Electrostatic Discharge and Grounding Guide for Cisco
NCS 2000 Series.
