IBM maintenance services and installation planning services do not cover verication of non-IBM racks
for compliance to Power Systems rack specications. IBM offers racks for IBM products that are tested
and veried by IBM development labs to comply with applicable safety and regulatory requirements.
These racks are also tested and veried to t and function with IBM products. The customer is
responsible for verifying with the rack manufacturer that any non-IBM racks comply with IBM
specications.
Note: IBM 7014-T00, 7014-T42, 7014-B42, 7953-94X, 7965-94Y, and 7965-S42 racks meet all the
requirements and specications.
Rack specications
The general rack specications include the following specications:
• The rack or cabinet must meet the EIA Standard EIA-310-D for 19-inch racks published August 24,
1992. The EIA-310-D standard species 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.
• 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).
* The range for models 9008-22L, 9009-22A, 9009-41A, 9009-42A, 9223-22H, and 9223-42H is
609.6 mm - 812.8 mm (24.0 in. - 32.0 in.).

• The vertical distance between mounting holes must consist of sets of three holes 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 (making each three-
hole set of vertical hole spacing 44.45 mm (1.75 in.) apart on center).
