Vertiv SR2N03020FAA2 20kW 3-Rack Integrated Power, Cooling & Fire Suppression Row Solution

Overview

The Vertiv SR2N03020FAA2 is a factory-configured, 3-rack integrated row solution rated at 20 kW total IT load capacity — purpose-built for organizations that need deployment-ready data center infrastructure without field-assembling individual components. Each of the three 42U x 600 x 1400 mm racks delivers up to 6.6 kW of usable IT capacity, and the entire row ships pre-integrated with dual cooling units, six 30A PDUs, a 20kW PMC power distribution system, and an integrated fire suppression system (FSS). At 3,600 mm end-to-end, this is a purpose-engineered row — not a rack kit you piece together on-site.

Where the SR2N03020FAA2 differentiates from non-fire-suppression variants in the same family is the built-in fire suppression cabinet, which adds 600 mm to the row footprint (compare the SR2N03020FAA1 without FSS at 3,000 mm). If your facility's compliance posture or insurance requirements mandate suppression at the row level — common in edge deployments, co-location suites, or isolated equipment rooms without overhead suppression — this is the variant to specify.

Key Features

• 20 kW Total IT Capacity: The row is rated for 20 kW aggregate across all three racks, with each rack individually rated at 6.6 kW. That's sufficient headroom for a dense mix of 1U and 2U servers without running near thermal limits — critical in environments where adding another row later isn't an option.
• Dual Cooling Units: Two dedicated cooling units provide N+1 cooling redundancy at the row level. If one unit faults or requires maintenance, the second carries the load without a service window forcing IT downtime. Single-cooling variants in this family (NAA2 and PAA2 suffixes) do not offer this protection.
• Six 30A PDUs (20kW PMC Distribution): Six PDUs, each rated at 30A, distribute power across the row via a 20kW Power Management Center. With six PDUs across three racks, that's two PDUs per rack — enough to dual-cord equipment and maintain outlet availability without daisy-chaining extension strips that void rack power ratings.
• Integrated Fire Suppression System: The FSS cabinet is factory-integrated, not field-added. This matters because field-retrofit suppression systems require additional validation, often involve third-party contractors, and may not satisfy AHJ (Authority Having Jurisdiction) requirements for pre-engineered system certification. Specifying the FAA2 variant means suppression is part of the manufactured assembly.
• 42U Rack Depth (1400 mm): The 1400 mm internal depth accommodates today's longer server chassis — 1U rack-mount servers commonly run 700–900 mm deep, and some GPU compute nodes exceed 1,000 mm. The 600 mm width is standard, keeping the row compatible with typical raised-floor tile spacing and hot-aisle/cold-aisle containment accessories.
• 3,600 mm Row Length (Pre-Verified Footprint): At 3.6 meters end-to-end, the SR2N03020FAA2 fits within a standard 4-meter data hall module with clearance for front/rear aisle access. If your room is tighter, the non-FSS SR2N03020FAA1 at 3,000 mm saves 600 mm — but you sacrifice suppression.
• Factory-Configured Row Architecture: Pre-wired and pre-integrated at the factory reduces commissioning time on-site. Instead of coordinating separate rack, PDU, cooling, and suppression deliveries, a single PO covers the complete assembly — relevant when project timelines are fixed and site access is limited.

Integration & Compatibility

The SR2N03020FAA2 is part of Vertiv's SR2 integrated row solution family, which spans 2- to 5-rack configurations at both 10 kW and 20 kW power tiers, with and without fire suppression. All configurations share the 42U x 600 x 1400 mm rack form factor and 30A PDU type, making it straightforward to plan a multi-row deployment using consistent infrastructure. The 20kW PMC distribution system in this variant is compatible with site power feeds requiring 30A branch circuits — confirm your facility's panel configuration before ordering, as the PMC is not field-reconfigurable to a different amperage tier. Explore the full Vertiv infrastructure catalog for complementary rack accessories, cooling components, and UPS systems that pair with this row solution. For sites evaluating row-based versus room-based cooling architecture, see the data center infrastructure category for context across deployment models. If you're sizing power distribution for this row, the rack PDU selection guide covers branch circuit planning and outlet density considerations that apply directly here. For organizations running structured cabling into this type of row deployment, network cabinets and racks offers compatible containment and cable management options.

Frequently Asked Questions

Q: What is the difference between the SR2N03020FAA2 and the SR2N03020FAA1?

A: Both are 20kW, 3-rack configurations with dual cooling units and six 30A PDUs. The SR2N03020FAA2 includes an integrated fire suppression system (FSS) and has a longer row footprint — 3,600 mm vs. 3,000 mm for the FAA1. If your deployment does not require fire suppression, the FAA1 saves 600 mm of floor space.

Q: Does the SR2N03020FAA2 include cooling redundancy?

A: Yes. This configuration includes two cooling units, providing N+1 cooling redundancy at the row level. Single-cooling variants in the SR2 family (NAA2 and PAA2 suffix models) carry only one cooling unit and do not provide this redundancy.

Q: What is the per-rack power capacity of the SR2N03020FAA2?

A: Each of the three racks is rated at 6.6 kW, for a combined 20 kW total across the row. PDU distribution provides two 30A PDUs per rack, supporting dual-corded equipment configurations.

Q: How many PDUs are included with the SR2N03020FAA2, and what amperage are they?

A: Six PDUs are included, all rated at 30A, managed through a 20kW PMC power distribution system. That equates to two PDUs per rack across the three-rack row.

Q: What is the total floor footprint of the SR2N03020FAA2?

A: The row measures 3,600 mm in total length. Individual racks are 42U x 600 mm wide x 1,400 mm deep. The 600 mm additional length compared to the non-FSS FAA1 variant is occupied by the fire suppression system cabinet.

Q: Is the SR2N03020FAA2 available without fire suppression?

A: Yes. The SR2N03020FAA1 is the equivalent configuration — 20kW, 3 racks, dual cooling, six 30A PDUs — without the integrated fire suppression system, at a shorter 3,000 mm row length. Select the FAA1 if your facility has overhead suppression coverage or if local code does not require row-level suppression.

The SR2N03020FAA2 is the configuration I reach for when a client needs row-level infrastructure that's complete at the time of delivery — not a procurement exercise across three separate vendors for racks, cooling, and suppression. The integrated fire suppression system is the key differentiator here: it adds 600 mm to the footprint versus the non-FSS FAA1, but in isolated equipment rooms and edge data center suites where overhead suppression isn't present, that's often non-negotiable from a compliance standpoint. The two cooling units mean you're not running a single point of failure at the thermal layer in a 20kW row — that's the right call for anything running production workloads.

Technical Highlights:

• Dual Cooling Units (N+1 Redundancy): Two cooling units at 20kW total load means one can service or fault without impacting IT uptime — a meaningful reliability step up from the NAA2 and PAA2 single-cooling variants in the same family.
• 6.6 kW Per Rack: At 6.6 kW per rack across three racks, this row handles a realistic mix of 1U and 2U compute without hitting thermal ceilings. It's not a hyperscale density target, but it's right-sized for edge compute, branch office server rooms, and mid-tier enterprise deployments.
• Six 30A PDUs via 20kW PMC: Two PDUs per rack at 30A supports dual-corded server configurations — which is how you should be running production equipment anyway. The PMC handles distribution centrally, keeping branch circuit management at the row level rather than scattered across individual rack strip configurations.

Deployment Considerations:

• The 3,600 mm total row length is the number to confirm first against your floor plan — the FSS cabinet accounts for the extra 600 mm over the FAA1. Verify aisle clearance on both the hot and cold sides before finalizing the layout, especially in rooms with fixed structural constraints.
• The 30A PDU type is fixed at the factory. If your site's branch circuits or panel configuration don't support 30A feeds, this is not a field-adjustable parameter — validate your electrical infrastructure before specifying this row.

The SR2N03020FAA2 is well-matched to isolated equipment rooms in healthcare, financial services branch offices, or edge co-location suites — anywhere that a code-driven or insurance-driven fire suppression requirement exists at the rack row level and overhead building systems can't satisfy it.
