Physical Dimensions and Mounting
The diagram illustrates the physical layout and dimensions of the 1U Redundant power supply unit. Key dimensions are provided: overall length is 205.0 mm ± 0.5 mm, width is 106.0 mm ± 0.5 mm, and height is 40.5 mm ± 0.3 mm. Mounting details include four #6-32UNC threaded holes on the front panel. These holes are positioned 6.1 mm ± 0.3 mm and 18.0 mm ± 0.3 mm from the edges, and are spaced 113.4 mm ± 0.3 mm and 106.0 mm ± 0.3 mm apart. The diagram also indicates airflow direction with an arrow and shows two AC power input connectors on the rear panel. Labels for "IC LABEL" and "SPEC LABEL" are present on the unit's surface. A simplified internal view suggests the integration of a main power module and a redundant module.
