Caution 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 be metallically connected to interfaces which 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 4) 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. The Catalyst 4900 Series Switches have AC power ports that are intended for deployments where an external Surge Protective Device (SPD) is utilized at the AC power service equipment (see definition in National Electric Code). The Catalyst 4900 Series Switches are designed for a Common Bonding Network (CBN) installation. The Catalyst 4900 Series Switches can be installed in network telecommunication facilities or locations where the National Electric Code applies. 78-18039-02 Catalyst 4900 Series Switch Installation Guide C-41
