Where Legrand sits in the stack
Legrand's placements in this catalog cover 9 parts, from layer 4 (servers, racks & integration) to layer 7 (electrical: power distribution (grid to rack)). 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
- 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.
- 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.
- Rear-door heat exchangers — A heat exchanger mounted on the rear door of a server rack that cools exhaust air with chilled water or refrigerant before it leaves the rack, without cooling the chips directly.
- LV switchgear, switchboards, panelboards — Low-voltage electrical distribution equipment — switchgear, switchboards, and panelboards — that receives power from MV/LV transformers and distributes it onward to busway, PDUs, and building loads.
- Busway / busbar trunking — Rigid, modular busbar systems that carry power along a data hall's overhead or perimeter path with tap-off points, used as an alternative to running individual cables to each row.
