Note: Because the 5079 1.8 m storage/PCI expansion unit consists of two 5074 storage/PCI expansions, electrical requirements for each 5074 need to be planned for individually. Hence, the (1) and (2) represent the specs for each 5074. The 5074 requires the appropriate receptacle for the power cord included with each 5074. The usable length of the power cord for the top/upper 5074 is reduced by 1.2 m (4 ft.) because of the routing inside the 1.8 m enclosure. Therefore, a 4.3 m (14 ft.) cord results in a usable length of 3 m (10 ft.), and a 2.7 m (9 ft.) cord results in a usable length of 1.5 m (5 ft.). For a description of noise emission values, see the Acoustics chapter of the Site Preparation and Physical Planning Guide, SA76-0103.

For information about floor loading, contact your IBM® service or installation planning representative. Because the thickness of the covers are negligible, the height, width, and depth of the overall dimensions may be used in floor loading calculations.
