Lenovo ThinkSystem 48U Onyx Heavy Duty Rack Cabinet | Rack Cabinet Enterprise

Support high-density infrastructure with a rack cabinet designed for sustained enterprise deployment. The Lenovo ThinkSystem 48U Onyx Primary Heavy Duty Rack Cabinet gives data center teams 48U of usable space in a 23.6 in wide, 47.2 in deep enclosure built to hold up to 3,999 lb. That capacity matters when you are consolidating servers, storage, and supporting equipment into a single footprint and need the rack structure to stay predictable under load. At 89.6 in tall, this cabinet is sized for floor-standing installation in server rooms and controlled data center environments. Cable management is included to help keep power and data runs organized as systems are added, replaced, or re-cabled. The heavy-duty construction and substantial approximate weight of 582.01 lb reflect a chassis intended for permanent infrastructure, not light-duty staging. For teams standardizing on Lenovo ThinkSystem hardware, this cabinet provides the physical foundation needed for clean deployment, service access, and long-term expansion planning. It is the kind of rack you choose when the cost of instability, cramped cable routing, or premature replacement is higher than investing in the right enclosure from the start.
