Considerations

Please pay attention to the footnotes indicated in the tables because they provide important information on using the rails in different racks and circumstances.

It is assumed that rack mount peripherals and cable bundles do not protrude into the space directly behind the systems.

Note that rail kits with a Rail Identifier code have been designed to be compliant with the Server System Infrastructure (SSI) Specification for Computer Server Cabinet Enclosures & Racks, which specifies a minimum offset distance for return flanges on the rack mounting flanges to allow sufficient room for mounting the rail kits, as indicated in the following figure.

Some third-party racks may not meet this requirement; it's not feasible to provide a solution for every circumstance.
