Original equipment manufacturer racks- IBM Power E1050

The system can be installed in a suitable OEM rack if that the rack conforms to the EIA-310-D standard for 19-inch racks. This standard is published by the Electrical Industries Alliance. For more information, see IBM Documentation.

IBM Documentation provides the general rack specifications, including the following information:

Ê The rack or cabinet must meet the EIA Standard EIA-310-D for 19-inch racks, which was published August 24, 1992. The EIA-310-D standard specifies internal dimensions, for example, the width of the rack opening (width of the chassis), the width of the module mounting flanges, and the mounting hole spacing.

Ê The front rack opening must be a minimum of 450 mm (17.72 in.) wide, and the

rail-mounting holes must be 465 mm plus or minus 1.6 mm (18.3 in. plus or minus 0.06 in.) apart on center (horizontal width between vertical columns of holes on the two front-mounting flanges and on the two rear-mounting flanges).

Figure 3-12 is a top view showing the rack specification dimensions.

Ê The vertical distance between mounting holes must consist of sets of three holes that are spaced (from bottom to top) 15.9 mm (0.625 in.), 15.9 mm (0.625 in.), and 12.7 mm (0.5 in.) on center, which makes each three-hole set of vertical hole spacing 44.45 mm (1.75 in.) apart on center.

Figure 3-13 shows the vertical distances between the mounting holes.

Ê The following rack hole sizes are supported for racks where IBM hardware is mounted:

– 7.1 mm (0.28 in.) plus or minus 0.1 mm (round)

– 9.5 mm (0.37 in.) plus or minus 0.1 mm (square)

The rack or cabinet must be capable of supporting an average load of 20 kg (44 lb.) of product weight per EIA unit. For example, a four EIA drawer has a maximum drawer weight of 80 kg (176 lb.).
