Where Eaton sits in the stack
Eaton's placements in this catalog cover 21 parts, from layer 4 (servers, racks & integration) to layer 9 (building shell, site & construction). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Power shelves & PSUs — The rack-mounted power shelves that convert facility AC or DC input into the regulated rail distributed to trays across the rack, built to the Open Rack V3 33 kW-class spec used in rack-scale AI systems.
- Enclosures — The rack cabinet frame itself — the enclosure that chassis and trays mount into, sold either as a standalone product or built in-house by the rack ODM.
- In-rack busbar & power whips — The high-current busbar and cabling that carries power from the rack's power shelves to each tray, including Nvidia's specified ±48 V / 1,400 A busbar used in rack-scale liquid-cooled systems.
- Rack PDUs — The power distribution units mounted in or beside a rack that meter and distribute power to individual devices, sitting between facility power and the rack's internal busbar or whips.
- Quick disconnects — Blind-mate connectors (UQD or UQDB) that let a compute tray or cold plate be connected to or disconnected from the coolant manifold without draining or spilling the loop.
- and 16 more in the table above.
