Rack installation specications that are not purchased from IBM
Learn about the requirements and specications for installing IBM systems into racks that were not
purchased from IBM.
Learn about the requirements and specications for 19-inch racks. These requirements and specications
are provided as an aid to help you understand the requirements to install IBM systems into racks. It is
your responsibility, working with your rack manufacturer, to ensure that the rack that is chosen meets the
requirements and specications that are listed here. Mechanical drawings of the rack, if available from the
manufacturer, are recommended for comparison against the requirements and specications.
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: The 7965-S42 rack meet all the requirements and specications.
Rack 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). Figure 1. Rack specications (top-down view).
