The SPARC M8-8 and SPARC M7-8 servers, and the associated rackmounting hardware kit, are compatible with 1200-mm Oracle racks only (either the Sun Rack II 1242 rack or the Oracle Rack Cabinet 1242). The servers have not been tested in non-Oracle racks.
If you will install the server in a non-Oracle rack, ensure that the non-Oracle rack meets the server installation requirements, which include (but are not limited to) the following:
The stand-alone server must be placed on a rack shelf in the non-Oracle rack
The rack shelf must be capable of supporting a minimum weight of 425 lbs (193 kg)
The rack shelf must be designed for the rack being used
Obtain the rack shelf from the rack vendor. Installing a stand-alone server in non-Oracle racks using the included rackmounting hardware kit is not supported.
