EXECUTION

1.21 GENERAL

Install equipment and components in accordance with manufacturer's written instructions, in compliance with NEC, and with recognized industry practices. Ensure that all work complies with specifications and serves the intent of the construction documents. Cabling and equipment shall be installed in accordance with good engineering practices as established by the EIA/TIA and the NEC.

1.22 INSTALLATION

A. Cabling - General:

Provide dedicated horizontal cable runs from data closets to all “terminated" information jacks as described above and indicated on the Drawings.

Where data or voice outlets are shown on plans, this Contractor shall provide jack termination, faceplate, and cabling.

Provide Modular Information Outlets in outlet boxes for all "terminated" data information jacks.

Excess cable behind faceplate connections shall be pulled back into ceiling spaces and secured in such a manner as to prevent damage to cabling or connections.

A minimum 10 foot loop of extra horizontal cable shall be secured in the accessible ceiling space.

Tighten connectors and terminals, including screws and bolts, in accordance with equipment manufacturer's published torque tightening values for equipment connectors.

Avoid excessive and sharp bends that may damage cabling. Do not exceed manufacturer's recommended pulling tensions for backbone and horizontal cables.

Allow sufficient slack (10 feet) in cable to prevent premature deterioration of cable system components and to assist in the maintenance and servicing of cable and/or other building systems and components.

Provide Cable Distribution J-Hooks as necessary to route and support cables within the data closet. All cables shall be properly supported.

Provide Velcro straps to bundle and organize cabling for a quality and professional installation. Vinyl/plastic tie wraps are prohibited.

Fittings or connections are allowed only at the input and output of devices. Splicing shall not be accepted in cable runs. Spliced cable runs shall be rejected and replaced with continuous cables, prior to acceptance.

Separation of Wires: Comply with EIA/TIA569 rules for separation of UTP cables from potential EMI sources.

All cabling outside the data closet shall be routed in conduit or wire way, installed by the electrical contractor.

Conduit fill shall not exceed 40%. This applies to both raceways and sleeves. Each conduit end not terminated in a box shall be equipped with a protective insulator or sleeve to cover the conduit end to protect the wire or cable during installation and remaining in the conduit.

B. Sleeving: All cabling penetrating a wall or floor and not in a raceway shall be sleeved. A penetrator sleeve system and method for using same provides an encasement for wires and cables passing through a wall or floor. The system should include appropriate securing devices for tightly retaining the penetrating element in place. This will also create a space between the penetrating element and surrounding structure, which must be fire stopped in order to restore the fire-resistance rating of the parent assembly. The penetrating element shall be one of the following;

1. EMT conduit with bushed ends.

2. Prefabricated fire-rated pathway. Recommend the following or approved equivalent. Follow manufacturer’s conduit fill recommendations.

EZ-PATH Fire Rated Pathway Spec Seal Ready Sleeve C. Fire stopping: Provide fire stopping after cabling installation at all fire wall/floor penetrations. Contact VA project manager to determine acceptable fire stopping materials for use during the installation.

D. Grounding: The general contractor shall be responsible for installing a ground bus adjacent to the rack. Ground all racks and cable runway to this ground bus. The contractor shall provide a #6 copper conductor from each rack/runway to the ground bus. Ground equipment per manufacturers’ instructions and NEC requirements.

E. Labeling, in accordance with VA Standards:

Label patch panel terminations with the identical numbers used at the outlets.

Label both ends of each cabling run within 6 inches of termination points with marker and flag ties, a label machine, or approved equal. Label the room end of the cable with the data closet identification number (closet number and jack number) and label the data closet end of the cable with the room jack number (room number, voice and data jack number).

Whenever possible, cross connect riser pairs shall be run sequentially.
