Vertiv SR2N04020FAA1 20kW 4-Rack Integrated Row Data Center System

Overview

The Vertiv SmartRow 2 SR2N04020FAA1 is a factory-integrated, 4-rack micro data center row designed for facilities that need a self-contained compute environment without building out a dedicated raised-floor computer room. At 20kW total power capacity across four racks — 5kW per rack — it targets edge deployments, remote offices, manufacturing floors, and branch IT rooms where a full-scale data center is impractical but downtime is not acceptable. The system ships with power distribution, in-row cooling, and cold/hot aisle containment pre-integrated, which cuts commissioning time compared to assembling individual components from separate vendors. If you are evaluating Vertiv infrastructure solutions for a dense edge or secondary-site deployment, this row system is worth a close look.

Key Features

• 2N Power Redundancy on 208V, 3-Phase: Dual independent power paths eliminate single-point failure on the electrical supply side. The 175A main breaker rating and 208V 3-phase, 4-wire + PE input means the system connects directly to typical commercial three-phase distribution without step-down transformers — a real factor in facilities already running 208V switchgear.
• N+1 Cooling Redundancy with 2 In-Row Cooling Units: Two in-row coolers serve the 4-rack envelope, so one unit can fail or go offline for maintenance while the other maintains thermal control. For a micro data center row running 24/7 without dedicated facilities staff, this is the operational safety net that keeps a single cooling failure from becoming a thermal shutdown event.
• Cold and Hot Aisle Containment: The enclosed containment design prevents hot exhaust air from recirculating back into server intakes. At 5kW per rack, mixing hot and cold air would force the cooling units to work harder than their design intent, increasing energy consumption and reducing effective cooling headroom. Containment preserves both PUE efficiency and rack thermal margins.
• 5kW per Rack Load Capacity: Each of the four racks supports up to 5kW of IT load. That headroom comfortably handles dense switching, 1U/2U servers, and network appliances but is not sized for GPU clusters or high-density compute nodes that can exceed 10–20kW per rack. Verify your per-rack load budget before specifying this model.
• Compact Footprint at 3600 × 1400 × 2250 mm: The row measures roughly 11.8 ft long × 4.6 ft deep × 7.4 ft tall. The minimum staging area requirement is 25.77 m² (approximately 277 sq ft), so confirm your floor plan accommodates both the installed footprint and the clearance needed to move the system in during installation. At 2710 kg system weight, structural floor loading must be assessed before site selection.
• 15A Condenser Breaker / 118 kg per Condenser Dry Weight: The condensing units are sized and circuit-protected independently from the main IT load path. At 118 kg dry weight each, condenser placement and refrigerant line routing must be factored into the site preparation scope — this is not a plug-and-play task on an unprepped floor.
• Operating Range 5°C–40°C / Up to 80% RH / 28°C Max Dew Point: The system tolerates a wide intake temperature band suitable for warehouses, manufacturing annexes, and non-climate-controlled equipment rooms. The 80% RH ceiling and 28°C dew point limit are standard commercial envelope ratings; condensing environments or coastal high-humidity locations should be evaluated carefully against these limits.

Integration and Compatibility

The SR2N04020FAA1 is designed as a turnkey power and cooling row that integrates with existing facility electrical infrastructure running 208V 3-phase distribution. The 175A main breaker dictates upstream panel and feeder wire sizing — coordinate with your electrical contractor early in the project. Cooling loop design, including condenser placement and refrigerant line runs, requires site-specific engineering that should involve Vertiv's application team or a qualified mechanical contractor. The containment system is designed to work with standard EIA-310 rack equipment, so existing servers, switches, and appliances slot in without modification. For rack and enclosure planning, factor the 5kW-per-rack ceiling into your load distribution plan across all four positions. Remote monitoring integration and management interface details should be confirmed against the full Vertiv SmartRow 2 documentation for your specific firmware and DCIM environment.

Frequently Asked Questions

Q: What is the total power capacity of the SR2N04020FAA1, and how is it distributed across racks?

A: The SR2N04020FAA1 supports 20kW total across 4 racks, rated at 5kW per rack. This assumes balanced load distribution — overshooting the 5kW limit in any single rack position can create localized thermal issues even if the aggregate 20kW ceiling is not breached.

Q: What electrical supply does the SR2N04020FAA1 require?

A: The system requires 208V, 3-phase, 4-wire + PE input with a 175A main breaker. A separate 15A breaker serves each condenser unit. Confirm your facility's upstream panel capacity and feeder gauge with a licensed electrician before ordering.

Q: What cooling redundancy level does the SR2N04020FAA1 provide?

A: The system uses N+1 cooling redundancy with 2 in-row cooling units serving the 4-rack row. One unit can fail or go offline for service while the remaining unit maintains cooling — essential for 24/7 environments without on-site facilities staff.

Q: What are the minimum floor space and structural requirements for the SR2N04020FAA1?

A: The installed row measures 3600 mm × 1400 mm × 2250 mm (approximately 11.8 ft × 4.6 ft × 7.4 ft) and requires a minimum staging area of 25.77 m² (roughly 277 sq ft). System weight is 2710 kg — structural floor loading capacity must be verified before siting this system.

Q: What are the environmental operating limits for the SR2N04020FAA1?

A: The system operates between 5°C and 40°C (41°F–104°F), up to 80% relative humidity, with a maximum dew point of 28°C. These limits make it suitable for equipment rooms and semi-conditioned spaces, but condensing or very high-humidity environments should be reviewed against these thresholds.

Q: Does the SR2N04020FAA1 include aisle containment?

A: Yes. The system includes both cold aisle and hot aisle containment as part of the integrated row design, preventing hot exhaust recirculation into server intakes and maintaining the thermal efficiency of the in-row cooling units.

The SR2N04020FAA1 is a factory-integrated row system, and that matters more than it might sound at first. When you're deploying compute infrastructure in a remote office, a manufacturing annex, or an edge facility where you don't have a raised-floor data center to work with, the alternative to a pre-integrated row like this is sourcing racks, PDUs, cooling units, and containment separately — and then commissioning all of it on-site. The SmartRow 2 compresses that scope significantly. What you're buying here is 2N power redundancy, N+1 cooling, and contained airflow in a single coordinated system rated to handle 20kW across four rack positions.

Technical Highlights:

• 2N Power Redundancy at 208V 3-Phase: Dual independent power paths on a 175A main breaker means a single electrical supply failure does not take the row down. For a remote site with limited facilities support, this is a meaningful operational safeguard — not just a spec checkbox.
• N+1 Cooling with 2 In-Row Units: Both coolers share the load under normal operation, so if one trips or needs maintenance, the other carries the row. At 5kW per rack — 20kW aggregate — thermal margin is tight enough that losing cooling entirely would produce rapid temperature rise. The N+1 design prevents that single-unit failure scenario from cascading.
• Cold and Hot Aisle Containment Included: Containment is not optional at this density level. Without it, hot exhaust recirculates into the cold aisle and the in-row coolers effectively fight themselves. The integrated containment in this system is the difference between achieving the rated cooling performance and falling short of it in practice.

Deployment Considerations:

• The 2710 kg system weight is the first site-prep question to resolve. Most standard commercial floors are rated for 250–500 kg/m² — at the row's footprint that math can get tight fast. Get a structural engineer's sign-off before committing to a location.
• The 15A condenser breaker and 118 kg dry weight per condenser unit mean refrigerant line routing and condenser placement need to be scoped as part of the installation plan, not figured out on delivery day. This is mechanical contractor territory, not just an IT rack install.

The SR2N04020FAA1 is the right call for a regional distribution hub, manufacturing plant IT room, or branch facility that needs genuine redundancy and self-contained thermal management without the cost and timeline of building a dedicated computer room — specifically in sites already wired for 208V 3-phase distribution.
