This SmartRack® 45U rack enclosure is designed for large, heavy AI servers that often do not fit into standard racks. The SRH452446W is constructed from heavy-duty steel 2.5 millimeters thick with reinforced structural elements, including extra welds and gussets for greater strength, extra connection points, and upgraded casters and levelers to support more weight. This cabinet has a maximum stationary load capacity of 5000 pounds (2268 kilograms) and a maximum rolling load capacity of 3500 pounds (1588 kilograms). The reversible front door, split rear doors and removable side panels lock securely with the included keys to help prevent damage, tampering or theft. The doors and side panels are designed for quick release, making it simple to access connected equipment and cabling with little effort. The removable roof panel has strategically placed pass-throughs to accommodate cables from vertical 0U PDUs and other equipment. The perforated front and split rear doors allow generous airflow from front to rear to help keep your equipment cool and functioning at its peak.
