Table 3 GR-1089 Installation and Caution Instructions

Shielded cable grounded at both ends specified for copper telecom ports.

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 Cisco MDS 9000 Series Multilayer Directors has 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 Cisco MDS 9000 Series Multilayer Directors are designed for a Common Bonding Network (CBN) installation.

The Cisco MDS 9000 Series Multilayer Directors can be installed in network telecommunication facilities or locations where the National Electric Code applies.

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.

The DC return connection to this system should remain isolated from the system frame and chassis (DC-I) .

The nominal DC operating voltage is -48V DC.
