Installation Specifications
Site Planning Guide17
*1: A 2U power distribution unit is composed of two 1U power distribution units.
*2: These values are for each shelf when 24 drives are installed in a 2.5" type shelf, 12 drives are installed in a 3.5" type
shelf, or 60 drives are installed in a 60-drive type shelf.
*3: The value in the parentheses for the controller shelf and drive shelves includes the mass of the rack rail kit.
*4: These values are for the maximum load when all the available options are installed in an ETERNUS AX/HX.
*5: The operating test was performed in environments compatible with the Operating Condition Class A2 of the EU eco-
design directive (ErP Directive 2009/125/EC).
*6: For details about the sound level of the drive shelf, refer to "Table 11 Sound Level of the Drive Shelf" (page 17)
