What’s ORW? Double-Width Frame Large form factor rack frame based on the ORv3 HPR feature set. Next-Gen AI Ready Developed to support larger mass and physical footprint of multi- generation AI platforms. High Power Capacity Capable of higher overall power capacity using liquid cooled busbars (>700 kW). Flexible Architecture Designed to support many different possible power architectures seamlessly.

One Year On — the ORW journey Oct 14, 2025 v0.9.0 Spec Preliminary specification shared with the community at OCP Global 2025. Shared Mar 11, 2026 v0.9.5 Spec Contribution presentation delivered Rack & Power OCP Monthly Call Apr 28, 2026 v1.0.0 Release Base Spec & Meta Design Spec officially published. OCP EMEA 2026 Oct, 2026 ORW Updates - OCP Global Summit ORW status updates, one year after contribution Shared Next PVT Production & Validation → MP Ramp Production ramp is actively underway. In Progress

Specification status META DESIGN ORW Meta Spec Adds frame size (W×D×H), max payload, and base geometry including forklift channels/supports. ● Optional crane lift & floor-bolt points ● Cable grommets and routing management ● Accessory and bracket options BASE SPEC ORW Base Spec IT-equipment interfaces for the new wider form factor, busbar mounting interfaces, and OU/RU position requirements. Scope Exclusion Deliberately excludes overall size, payload, and base geometry — kept open for implementers. IT Gear Design Guide v0.1 preliminary specification Meta Design Collateral v1.0.0 Includes 3D CAD models, 2D technical drawings, and Bill of Materials (BOM)

ORW Design evolution How the ORW frame matured: Three engineering build phases — in PVT today. Every geometry change tracked build-to-build against a defined CAD freeze, with explicit in/out scope per hardware sample. Structural stiffness Base welded across multiple horizontal planes; mid-base assembly simplified and strengthened. Normal-mode FE analysis confirms the improvement. Dimensional control Rack parts redesigned to datum key components into position. Replacing manual build loops for tight, repeatable squareness Built for volume Part commonization, opened jig and weld access, paint relief and drainage, and molded-in ID features so ORW is never confused with ORv3 on the line. Takeaway: stiffer, squarer, and built for volume

Precise ORv3 alignment • Shifted ORW rail bottom-of-flange datum ~0.5 mm and trimmed IT- gear stepped land (44.7 → 44.2 mm). • Assembly datums & depth setting: Utilizes rack-interface outside face + hook bottom face; rear hard-stop flange sets IT-gear depth. Higher-load, tool-less rail • Supports 125 kg IT gear, a significant upgrade from 80 kg on ORv3 HPR. Riveted rail clip • Clip now riveted to the rail (previously snap-in) for increased stiffness and consistent engagement. Requalified latch mechanism • 625 N pull-out target, selected after evaluation of different design concepts IT Rail updates

• Test Scope • The rack was tested with a payload of 4,700kg (using dummy weights) • Testing Procedures • Vibration: • Random vibration • Drop Tests: • Rotational flat and edge drops • Flat Drop • Tilt Testing: • Four 17-degree tilt tests. • Performance: • No visual damage was observed on the crate or the rack following any of the tests • Structural squareness remained within the required tolerance throughout all post-test measurements. • Results: • All tests PASSED. Paired with a full crate, ORW rack demonstrated structural robustness and successfully met all defined qualitative and quantitative pass criteria Validation results Testing Setup @ DVT Stage
