Attachment A Specifications for Electronics Cabinets and Racks

Dated: March 18, 2024

1. Overview

1.1 Current Estimated Qty of Approximately 900 Cabinets.

1.2 Procured over an estimated 5-year period, 2026-2031.

1.3 BSA could potentially award one or multiple awardees at time of competitive solicitation.

1.4 BNL is currently evaluating 3 different cooling methodologies for the varying applications required to support the EIC project.

1.4.1 Heat Exchanger (HX) Cooled. This is a sealed rack with a water-to-air heat exchanger inside it which circulates air in a closed loop. The general design is that the HX blows cool air to front plenum created by the front door, sides, and chassis front panels. Air flows from the front through chassis (or between chassis) to the heat exchanger return.

1.4.2 Fan cooled ambient air. This is a rack with no heat exchanger, where fans direct cool, filtered ambient air from outside into the cabinet, and/or hot air from inside the rack to the outside.

1.4.3 Directed/Ducted forced air supply. This is a rack with no heat exchanger, where a source of cooled air is forced directly into the cabinet from ducting entering the lower side of the cabinet.

1.5 It is expected at time of final design, that racks will have varying overall dimensions for rack, doors, and rack base. Racks will also have the differing penetration requirements, depending on the cooling method, and cable access needs, these penetrations will either have blank panels, fans, filters, or other modifications to allow for cable access, AC delivery, or water fittings.

1.6 Where appropriate in your responses, please include assumptions for rack inputs (chilled water temperature, ambient air temperature, ducted/forced air temperature and flow rate, etc.)

1.7 BNL recognizes these unknowns will influence final pricing but is under the assumption that a sufficient budgetary quote can still be estimated by the supply base.

2. Standards

2.1 The standards listed below shall be used for the design of the specified equipment.

2.1.1 NFPA 70 National Electric Code (Latest Edition)

2.1.2 UL 1995 Heating and Cooling Equipment

2.1.3 UL 50 Cabinets and Boxes

2.1.4 NRTL Listed

3. General Design Specifications of Rack Enclosures

3.1 The proposed rack solutions shall be capable of maintaining a constant internal temperature of 75F +/- 3 degrees. The nominal expected building/ambient provided air temperature range is currently 68-75F +/-3 degrees.

3.2 The cooling system shall be designed such that cooling is delivered and heat is removed to maintain even temperature throughout the loaded rack.

3.3 All enclosure panels including doors, sidewalls, and topsides shall be directly connected to the frame.

3.4 Racks shall have removable side panels.

3.5 Mounting provisions shall allow for multiple racks to be bolted together in a side-by-side fashion.

3.6 Racks shall have gasketed front and rear doors.

3.7 The rack shall have 52 U (U=1-3/4”) available for front panels of mounted equipment. See Dimensional Table below for request varying options to evaluate.

3.8 The cabinets shall have a minimum width of 24 inches (±1/2 inch) and a maximum width of 31.5 inches (+/-1/2 inch) depending on the configuration option. See Pricing Table below for varying options to evaluate.

3.9 The internal racks shall have standard "U" rails configured to accept 19-inch equipment via

10-32 tapped holes in standard U spacing.

3.10 All rack solutions shall have adjustable front, middle and rear rails.

3.11 The rack shall have a maximum depth of either 36 inches (±1/8 inch) or 48 inches depending on the configuration. See Dimensional Table below for request varying options to evaluate.
