Description
The Lenovo ThinkSystem 42U Onyx Expansion Heavy Duty Rack Cabinet (7D6D0001WW) is a high-capacity, enterprise-grade 19-inch rack designed for high-performance server, storage, HPC, and data center environments. This expansion model is supplied without side panels, making it ideal for installation alongside an existing rack cabinet in a multi-rack row configuration.
Built around a standard 600 mm × 1200 mm footprint, the 42U cabinet provides extensive configuration flexibility while supporting fully integrated equipment loads up to 1,588 kg (3,500 lb). Its heavy-duty frame, square-hole mounting rails, integrated stabilization features, and cable-management provisions help simplify deployment and serviceability in demanding infrastructure environments.
The cabinet supports optional front and rear rack extensions, 0U and 1U power distribution options, cable-management accessories, and Lenovo Neptune direct-water-cooling infrastructure. Lockable doors, adjustable leveling pads, and integrated outriggers further enhance equipment security and stability.
