Vertiv SR2N05020FAA1 5-Rack 20kW Integrated Power and Cooling Row System

Overview

The Vertiv SR2N05020FAA1 is a factory-configured, 5-rack integrated row system engineered to deliver 20kW of total IT power capacity across a 4,200mm footprint — purpose-built for edge data centers, distributed enterprise computing rooms, and telecom facilities where power density, cooling redundancy, and rapid deployment matter. Each of the five 42U × 600 × 1400mm racks ships pre-integrated with the power distribution and cooling infrastructure, so commissioning is a matter of positioning, connecting to facility power, and loading equipment — not a multi-day installation project from individual components.

This configuration targets environments that need to absorb 20kW of IT load without hot-aisle/cold-aisle buildouts or raised floors. With 4 kW allocated per rack, the SR2N05020FAA1 suits mixed-density compute — blade servers, network gear, and storage appliances co-located in a single row — where heat management can't be left to perimeter room cooling alone.

Key Features

• 20kW Total Row Capacity: The system's 20kW PMC (Power and Cooling Management) distribution handles the full IT load across all five racks without requiring supplemental cooling infrastructure — a meaningful reduction in facility build cost versus deploying standalone room cooling for the same load.
• Dual Cooling Units (N+1 Redundancy): Two cooling units serve the five-rack row, giving you N+1 thermal redundancy. If one cooling unit needs maintenance or fails, the second continues to manage the full 20kW load. This is the configuration to specify when uptime is non-negotiable — the single-cooling-unit variants (SR2N05020NAA1, SR2N05020PAA1) don't provide this failover.
• Five 42U × 600 × 1400mm Racks: Standard 42U height with a 600mm width and 1,400mm depth accommodates nearly all standard 19-inch server, networking, and storage hardware. The 600mm width keeps the row compact; the 1,400mm depth provides adequate cable management clearance behind rear-mounted equipment.
• 4 kW Per Rack Allocation: At 4 kW per rack, this configuration targets moderate-density workloads. If your per-rack power draw runs higher — 8 to 10 kW for dense blade chassis, for example — evaluate a 3- or 4-rack variant in the SR2 family where capacity is concentrated into fewer enclosures.
• 10× 30A PDUs: Ten 30A PDUs distributed across the row provide two PDUs per rack — enough for dual-corded equipment with redundant power paths. The 30A circuit supports standard C13/C19-receptacle PDUs appropriate for the 4 kW per-rack load envelope without requiring high-amperage branch circuit provisioning.
• 4,200mm Assembled Row Length: The 4,200mm total footprint (roughly 13.8 feet) fits within a standard computer room bay or a dedicated edge deployments in a telecom room. Plan floor loading accordingly — a fully populated 5-rack IT row at this density is substantial.
• No Fire Suppression in Base Configuration: The SR2N05020FAA1 ships without integrated fire suppression. If local code or insurance requirements mandate in-rack suppression, the SR2N05020FAA2 adds that capability in the same 5-rack, 20kW layout at 4,800mm length.
• 20kW PMC Distribution: The integrated Power and Cooling Management infrastructure handles load balancing and distribution across the row centrally — eliminating the need to separately engineer and wire inter-rack power distribution after installation.

Integration and Compatibility

The SR2 row system integrates with Vertiv's broader infrastructure management ecosystem. The 20kW PMC distribution backbone is designed to interface with Vertiv monitoring and management platforms, enabling centralized visibility into power consumption and thermal performance across the row. For larger facilities deploying multiple rows, this visibility scales without requiring per-rack DCIM instrumentation.

The standard 42U rack form factor is compatible with all conventional 19-inch rack-mount equipment, EIA-310-compliant server and network hardware, and standard cable management accessories. Plan for facility-side 3-phase power provisioning to support the 20kW aggregate load — consult your facility electrical team for appropriate breaker sizing upstream of the PDUs.

Frequently Asked Questions

Q: How many IT racks are included in the SR2N05020FAA1?

A: The SR2N05020FAA1 includes five 42U × 600 × 1400mm IT racks, configured as an integrated row with shared power distribution and cooling infrastructure.

Q: What is the total IT power capacity of the SR2N05020FAA1?

A: The system supports 20kW total IT load, distributed at 4 kW per rack across the five enclosures, managed by a 20kW PMC distribution backbone.

Q: Does the SR2N05020FAA1 include cooling redundancy?

A: Yes. The SR2N05020FAA1 includes two cooling units, providing N+1 thermal redundancy for the row. This distinguishes it from the SR2N05020NAA1 and SR2N05020PAA1 variants, which ship with a single cooling unit.

Q: Does this configuration include fire suppression?

A: No. The SR2N05020FAA1 does not include integrated fire suppression. The SR2N05020FAA2 is the equivalent configuration with fire suppression added.

Q: How many PDUs are included, and what amperage?

A: The SR2N05020FAA1 includes 10 PDUs, each rated at 30A — two per rack — supporting dual-corded equipment with redundant power paths within each enclosure.

Q: What is the assembled row length of the SR2N05020FAA1?

A: The fully assembled row spans 4,200mm (approximately 13.8 feet). Plan floor space and pathway access accordingly before delivery and positioning.

Jerry Tildsen

The SR2N05020FAA1 is the configuration I'd reach for when a customer needs moderate-density row cooling with genuine thermal redundancy and doesn't want to piece together racks, PDUs, and in-row coolers from separate procurement tracks. The dual cooling units on this 5-rack, 20kW system are the spec worth anchoring on — you're not gambling on a single cooling unit to protect the full row load.

Technical Highlights:

• Dual Cooling Units: Two cooling units manage the 20kW row load together — if one goes offline for maintenance or failure, the remaining unit can sustain the load. The single-unit variants (NAA1 and PAA1) save floor space but forfeit this failover; factor that into your uptime SLA before choosing.
• 10× 30A PDUs (Two Per Rack): Dual-corded power paths per rack are built into the row design — you're not retrofitting A/B power after installation. For any equipment running redundant PSUs, this is table stakes.
• 4,200mm Row Footprint: At just under 14 feet assembled, this fits comfortably within a standard 10-foot × 20-foot dedicated server room bay with working clearance. Confirm your facility's door clearance and floor loading limits before delivery — five 42U enclosures plus cooling infrastructure is a significant logistics move.

Deployment Considerations:

• The SR2N05020FAA1 ships without fire suppression. If your facility's code authority having jurisdiction (AHJ) requires in-rack suppression — common in telecom exchange rooms and certain financial data centers — specify SR2N05020FAA2 instead, which adds suppression at 4,800mm total length.
• At 4 kW per rack, this system isn't the right fit for high-density GPU or blade chassis environments where per-rack draw can exceed 10–15 kW. In those cases, a 3-rack variant of the SR2 family with higher per-rack allocation (e.g., SR2N03020FAA1 at 6.6 kW per rack) is a better match.

This configuration is a strong fit for distributed enterprise edge deployments — regional offices, campus aggregation points, and manufacturing floor compute rooms — where a pre-integrated, thermally redundant row reduces both deployment time and the risk of a single-point cooling failure taking down all five racks simultaneously.
