Install a master hub cabinet that provides an environmentally cooled enclosure facility required for the sensitive network equipment to be furnished on this project. The cabinets ha I I be designed for the explicit use of housing sensitive electronic equipment (e.g., gigabit ethernet switches, 10/100 ethernet switches, media converters, port/terminal servers, fiber optics equipment, and other related components, etc.) within a controlled atmosphere required for the proper operating conditions for installed equipment and shall be furnished by the system manager. The master hub cabinet shall meet or exceed the following minimum requirements: a) Size: Dimensions shall be approximately 104"H x 108"W x 77"D; b) AC Unit/Cooling Unit: The cabinet shall have an AC unit/cooling unit(s) with a minimum total cooling capacity of 20,000 BTUs. The AC unit/cooling unit(s) shall be designed specifically for outdoor electronic enclosures and shall be designed for a fully-gasketed, leak -proof installation in accordance with the NEMA 4/4X enclosure rating. Refrigerant shall be CFC -free; c) Lighting: The cabinet shall include a switch controlled fluorescent light fixture providing adequate work lighting throughout the cabinet; d) Electrical Outlets: Two (2) separate duplex (GFCI) wall electrical outlets for test/maintenance equipment shall be provided. Two (2) separate standard duplex outlets shall be supplied for equipment power; e) Equipment Racks: Two (2) 19" EIA equipment racks with two (2) vertical and four (4) horizontal cable management panels per rack, placed as specified within the plan set; f) Ladder Racks: Ladder rack cable management system as depicted within the plan set shall be provided; g) Power Distribution: The cabinet shall provide for power distribution to all installed equipment racks, lighting and the air conditioning unit shall be provided; h) Lightning Protection System: Provide for lightning protection for the overall, integrated structure, including each metallic (copper) conductor penetrating the cabinet; i) Common Grounding System: A cabinet grounding system shall be provided; j) Cabinet Monitoring System: A cabinet monitoring system shall be provided to continuously monitor and report local conditions (temperature, humidity, smoke, and door alarm). 7.9.10 Construction Construct a flat, level, concrete base, meeting the requirements for Class 1, non-stressed concrete and shall be accepted according to Section 347 of the FDOT Standard Specifications, and the latest supplements. The minimum final grade shall be set at nominal 8" above the surrounding grade to ensure that water drains away from the cabinet. Restore surrounding surfaces to their original condition. 7.9.11 Method of Measurement The Detector Cabinet Type II, Detector Cabinet III, and Detector Cabinet VI shall be measured for payment at each site as installed. Detector Cabinet IV and its corresponding base (A268-4.1) shall be paid as each is installed. The Detector cabinet base installed shall be an appurtenance of the Type IV Detector Cabinet. The unit price for each master hub cabinet installed shall include all labor, equipment, foundations, mounting hardware, and miscellaneous material necessary for a complete and acceptable installation. The engineer's system manager will supply the cabinet assemblies as specified in the contract. 7.9.12 List of Items for Outside Plant Cabinets Communications Cabinet — 35"H x 24"W x 22"D, with concrete base Communications Cabinet — 51.25"H x 20"W x 18"D, with concrete base 40
