Cabinet is tested to 2,000kg static & dynamic load

Pentair tests the static load of its 2000x1200x800 and 600mm Schroff Varistar server cabinets based on exacting, internal specifications. Pentair uses a rigorous test weight of 2,000kg and the load capacity is increased incrementally. Deformation, not to exceed 5mm, is measured at five points of the cabinet rack and the 19" plane over a period of 72 hours. After deduction of the standard 25% safety tolerance, a static load capacity of 1,600kg is achieved for Schroff Varistar cabinets. It should be noted that not all manufacturers take this 25% tolerance into account.

The high load-carrying capacity is achieved with integrated cross beams capable of bearing greater loads. The selection of cross beams followed extensive in-house testing. Competing products from other cabinet manufacturers were tested for comparison. The selected cross beams feature holes spaced 25mm apart. This enables the user to move the 19" plane forward or backward in the cabinet, depending on how much room is needed in the front for cabling.

If it is necessary to move a server cabinet once it has been partially or fully loaded, e.g. for transportation or at the installation site, dynamic load also needs to be considered. Dynamic processes can challenge cabinet load capacity in a variety ways. Pentair typically recommends the use of a more rugged, heavy-duty rack and integrates additional stiffening elements. The platform's extensive palette of off-the-shelf expansion and accessory parts helped in making this upgrade available to customers. These cabinets are also tested by Pentair’s own rigorous design criteria resulting in projects meeting dynamic load capacities of up to 1,200kg.
