Vertiv SR2N02010PAA1 2-Rack 10kW Power-Redundant Row Cooling Solution

Overview

The Vertiv SR2N02010PAA1 is a pre-engineered, two-rack row solution designed for data center and edge deployments where both power density and power path redundancy are non-negotiable. Rated at 10 kW total capacity across two 42U × 600 × 1400 mm racks — 5 kW per cabinet — it ships as a configured assembly with four 30 A PDUs and a 10 kW Power Management Controller (PMC) distribution architecture, making it the right choice when you need dual-corded server feeds and centralized power monitoring in a compact two-rack footprint.

Where the baseline SR2N02010NAA1 gives you only two PDUs (one per rack, single-corded configuration), the SR2N02010PAA1 doubles PDU count to four, giving every rack two separate 30 A feeds. That's the practical difference between a single-path deployment and a genuinely redundant one — and it's the defining reason to select this SKU over the N-suffix variant if your server hardware has dual PSUs.

Key Features

• 10 kW Total Row Capacity, 5 kW per Cabinet: Each of the two 42U racks is rated to 5 kW continuous — practical for mid-density compute loads like network video recorders, edge compute nodes, or blade chassis at moderate utilization. Exceeding 5 kW per cabinet means stepping up to the 20 kW family (SR2N0X020 series), not adding PDUs to this unit.
• Four 30 A PDUs (2 per Rack): Dual PDUs per cabinet enable A+B power feed topology for dual-PSU servers and appliances. If one PDU circuit trips or the upstream breaker clears, connected equipment with dual PSUs stays online — the primary reason this SKU exists over the two-PDU SR2N02010NAA1.
• 10 kW PMC Distribution Architecture: The Power Management Controller layer centralizes distribution monitoring across both racks in a single 2100 mm row. Rather than managing two independent PDU chains, the PMC gives you a unified view of load, capacity headroom, and circuit-level status — useful for facilities teams managing multiple rows without per-rack manual checks.
• 42U × 600 × 1400 mm Rack Form Factor: Standard 600 mm width fits most raised-floor and on-slab data center aisles without aisle modification. The 1400 mm depth accommodates full-depth 1U–4U servers and storage sleds. 42U height matches the industry-standard enclosure so existing blanking panels, rail kits, and cable management accessories transfer over without procurement exceptions.
• 2100 mm Total Row Length: The two-rack assembly measures 2100 mm end-to-end — just under 7 feet. This is the shortest row configuration in the SR2N family, making it viable for smaller computer rooms or branch data closets where a three- or five-rack row (2700–4200 mm) wouldn't fit the available floor tile count.
• Single Cooling Unit: The SR2N02010PAA1 includes one cooling unit shared across both racks. If your facility requires redundant cooling (N+1), step up to the FAA1-suffix variant (SR2N02010FAA1), which adds a second cooling unit in a 2400 mm footprint. The single-cooler configuration here is sized for the 10 kW heat load — adequate but without thermal redundancy.
• No Fire Suppression (AAA1 Suffix): This configuration ships without integrated fire suppression. If local code or insurance requirements mandate suppression at the row level, the AA2-suffix family (e.g., SR2N02010PAA2) adds suppression in a 2700 mm footprint. Confirm with your AHJ before ordering.

Integration and Compatibility

The SR2N02010PAA1 is positioned within the broader Vertiv SmartRow SR2 product family, which scales from 2 to 5 racks and 10 to 20 kW per row. The 10 kW PMC used here is purpose-matched to the two-rack, 10 kW configuration; upgrading to a 20 kW load profile means selecting from the SR2N0X020 series rather than field-modifying the PMC in this unit. The 30 A PDU standard is consistent across the entire SR2N family, so branch circuit wiring at the upstream panel can follow a consistent 30 A receptacle design regardless of which row configuration you deploy later.

When planning upstream panel capacity, account for two 30 A circuits per rack — four 30 A circuits total for this two-rack row. At full 10 kW draw, that's approximately 41.7 A at 240V or 83.3 A at 120V aggregate; your upstream panel and feed conductors need to be sized accordingly before the row ships.

For buyers evaluating the broader Vertiv data center infrastructure lineup, this row solution integrates with Vertiv's monitoring and management ecosystem for centralized facility oversight. Pair it with appropriate power distribution and UPS solutions to build a complete power chain from utility input to rack outlet. If your project calls for more detailed pre-sales power planning, rack enclosure configurations and aisle containment options are also available to complete the physical infrastructure layer.

Frequently Asked Questions

Q: What is the difference between the SR2N02010PAA1 and the SR2N02010NAA1?

A: The key difference is PDU count. The NAA1 variant includes 2 PDUs (one per rack), supporting single-corded equipment. The SR2N02010PAA1 includes 4 PDUs (two per rack), enabling A+B dual-feed topology for dual-PSU servers. Both share the same 10 kW capacity, 42U rack dimensions, and 2100 mm row length.

Q: Does the SR2N02010PAA1 include fire suppression?

A: No. The AAA1 suffix indicates no integrated fire suppression. If fire suppression is required, the equivalent configuration with suppression is the SR2N02010PAA2, which adds suppression in a 2700 mm footprint.

Q: How many cooling units does the SR2N02010PAA1 include?

A: One cooling unit, shared across both racks. This is sufficient for the 10 kW heat load but provides no thermal redundancy. For N+1 cooling, select the FAA1-suffix variant (SR2N02010FAA1), which includes two cooling units in a 2400 mm footprint.

Q: What upstream circuit requirements does the SR2N02010PAA1 need?

A: The solution includes four 30 A PDUs — plan for four separate 30 A branch circuits at your upstream distribution panel. Confirm conductor sizing and breaker ratings with your electrical contractor based on local code and total anticipated load.

Q: Can this row solution be expanded to handle more than 10 kW?

A: No. The SR2N02010PAA1 is rated at 10 kW total with a 10 kW PMC — it is not field-upgradeable to 20 kW capacity. For higher density deployments, the SR2N0X020 family (SR2N03020, SR2N04020, SR2N05020 series) supports 20 kW across 3–5 racks.

Q: What are the physical dimensions of the SR2N02010PAA1 row assembly?

A: Each of the two racks is 42U × 600 mm wide × 1400 mm deep. The complete two-rack row assembly spans 2100 mm in total length (approximately 6 feet 10 inches end-to-end).

Jerry Tildsen

The SR2N02010PAA1 is the SKU I recommend when a project needs true A+B power redundancy in the smallest possible row footprint — two racks, 10 kW total, 2100 mm end-to-end. The four 30 A PDUs are the critical differentiator here: without that second PDU per cabinet, you're running single-corded, and any upstream breaker event takes the rack down. With this configuration, dual-PSU servers stay online through a single-circuit fault.

Technical Highlights:

• 4x 30 A PDUs (2 per rack): Enables true A+B feed topology — each rack has independent primary and secondary 30 A circuits, which is the minimum bar for Tier III-equivalent power path redundancy at the rack level.
• 10 kW PMC Distribution: Centralizes power monitoring and distribution management across both cabinets in a single controller — eliminates the need to manage two independent PDU chains and gives facilities teams a unified capacity view across the row.
• 5 kW per Cabinet: At 42U depth, 5 kW per rack supports mid-density loads (NVRs, edge compute, network appliances) comfortably. If you're running GPU nodes or high-density storage that pushes 8–10 kW per cabinet, this row is undersized — look at the 20 kW SR2N family instead.

Deployment Considerations:

• Plan four separate 30 A branch circuits at the upstream panel before the row ships — the PDU count doubles versus the NAA1 variant, and that upstream work often has the longest lead time on a data center build-out.
• Single cooling unit means no thermal redundancy: a cooling failure affects both cabinets simultaneously. If your SLA requires continuous uptime through a cooling fault, specify SR2N02010FAA1 (dual cooler, 2400 mm) instead — the 300 mm of additional row length is the trade-off.

This is the right row for a compact edge data room or branch office MDF where the floor plan can't accommodate a three- or five-rack row but the equipment still requires dual-corded power — think regional security operations centers running NVR clusters and network infrastructure with redundant PSUs that simply can't tolerate a single-path power failure.
