Vertiv SR2N04020FAA2 4-Rack 20kW Integrated IT Room with Fire Suppression

Overview

The Vertiv SR2N04020FAA2 is a pre-engineered, 4-rack integrated IT room delivering 20kW of total power capacity with built-in fire suppression — the FAA2 suffix is the key differentiator here. Purpose-built for edge deployments, branch data centers, and remote sites where you cannot staff a full data center but still need enterprise-grade power, cooling, and protection in a single footprint. At 4,200mm end-to-end, this row integrates all four 42U x 600 x 1400mm enclosures into one managed assembly rather than four independently cooled and powered racks bolted together.

This unit ships as part of the Vertiv SR2 integrated IT room line, designed to collapse the build-out complexity of a traditional server room enclosure project into a factory-configured, site-ready solution.

Key Features

• 20kW Total Power, 5kW Per Rack: With 20kW distributed evenly across four enclosures, each rack handles up to 5kW — appropriate for mid-density compute, networking, and storage loads. If your per-rack density exceeds 5kW, you need to right-size to the 3-rack 20kW variant (SR2N03020FAA2, at 6.6kW per rack) or a higher-density configuration.
• Dual Cooling Units: The FAA2 configuration includes 2 cooling units — unlike the NAA2 (1 unit) and PAA2 (1 unit) variants in the same 4-rack family. Redundant cooling means one unit can fail or be serviced without a thermal event taking down active equipment — critical for unattended remote sites.
• 8x 30A PDUs: Eight 30-amp PDUs distribute power across all four racks, giving you 2 PDUs per enclosure. Dual-cord equipment can connect to separate PDUs for path-level redundancy without additional accessories.
• 20kW PMC Power Distribution: The integrated 20kW Power Management Cabinet handles power entry, distribution, and metering at the row level. Centralizing power management at the PMC simplifies capacity planning and avoids the per-rack circuit provisioning work that drives up installation labor on ad-hoc builds.
• Integrated Fire Suppression (FAA2): The AAA2 suffix confirms factory-installed fire suppression. This is the specification that distinguishes this SKU from SR2N04020NAA1 and SR2N04020PAA1 — sites requiring NFPA 75 or local code compliance for unattended IT spaces should specify an FAA2 variant. Confirm local AHJ requirements before finalizing.
• 42U Enclosures, 600mm Wide x 1400mm Deep: The 1400mm depth accommodates most 2-post and 4-post rackmount equipment, including deep UPS units and high-density patch panels. The 600mm width is standard — verify aisle clearance and doorway widths before delivery; at 4,200mm assembled length, pre-positioning logistics matter.

Integration and Compatibility

The SR2N04020FAA2 integrates into Vertiv's managed infrastructure ecosystem. The row-level PMC supports monitoring and alerting compatible with data center infrastructure management platforms. For sites pairing this unit with active compute, review PDU outlet counts against your equipment manifest before finalizing — 8 PDUs across 4 racks gives you limited outlet density per enclosure; high-port-count deployments may require PDU extensions. Coordinate power feed requirements (the 20kW PMC requires appropriate upstream breaker and cabling) with your facilities team early in the project cycle.

When specifying rack accessories, cable management arms, and KVM infrastructure, verify that accessory depths are compatible with the 1400mm enclosure depth — oversized accessories can block airflow paths in integrated row cooling configurations.

Frequently Asked Questions

Q: What is the difference between the SR2N04020FAA2 and the SR2N04020NAA2 or SR2N04020PAA2?

A: All three are 4-rack, 20kW configurations. The NAA2 includes 1 cooling unit and 4 PDUs. The PAA2 includes 1 cooling unit and 8 PDUs. The SR2N04020FAA2 includes 2 cooling units, 8 PDUs, and integrated fire suppression — the highest protection level in the 4-rack 20kW family.

Q: Does the SR2N04020FAA2 include fire suppression?

A: Yes. The FAA2 suffix indicates factory-installed fire suppression is included. Consult your local authority having jurisdiction (AHJ) to confirm code compliance requirements for your installation site.

Q: How many racks and what is the per-rack power capacity?

A: The SR2N04020FAA2 includes 4 racks, each rated at 5kW capacity, for a total system capacity of 20kW.

Q: What are the overall assembled dimensions?

A: The assembled row is 4,200mm in length. Each enclosure is 42U x 600mm wide x 1400mm deep. Plan your site layout accordingly — doorway and aisle widths must accommodate the assembled row or allow for staged on-site assembly.

Q: How many PDUs are included and what type?

A: Eight 30-amp PDUs are included, providing 2 PDUs per enclosure across the 4-rack row. This supports dual-cord equipment for power path redundancy.

Ted Perry

The SR2N04020FAA2 is the configuration I recommend when a remote or branch site needs enterprise-grade redundancy without a dedicated facilities team on-site. The dual cooling units in this FAA2 variant are the spec that sets it apart from the NAA2 and PAA2 builds — at 5kW per rack across four enclosures, losing one cooling unit in an unattended room is a real risk, and having the second unit maintain thermal control until someone gets on-site is not optional in those deployments.

Technical Highlights:

• Dual Cooling Units: Two cooling units at 20kW total load means each unit carries the full row load in a failover scenario — confirm your cooling unit BTU ratings against your actual equipment heat output before commissioning, not after.
• 8x 30A PDUs: Two 30A PDUs per enclosure supports dual-corded server and storage configurations without additional field accessories. At 5kW per rack, you have headroom for most 1U and 2U server loads before hitting density limits.
• Integrated Fire Suppression: Factory-installed suppression means AHJ coordination happens at the product specification stage, not during construction. Verify local code requirements — suppression agent type matters for the equipment housed inside.

Deployment Considerations:

• At 4,200mm assembled length, pre-delivery site survey is non-negotiable — measure every doorway and corridor on the delivery path. Partial on-site assembly may be required depending on access constraints.
• The 20kW PMC requires appropriate upstream electrical feed. Coordinate panel capacity and breaker sizing with your facilities or electrical contractor before the unit ships — field changes after delivery are expensive.

This configuration fits a manufacturing plant IT closet, a retail distribution hub, or a branch office that needs enterprise infrastructure without a raised-floor data center — anywhere the combination of cooling redundancy, integrated PDUs, and fire suppression in a single contracted unit reduces project risk.
