The rails can be used in a threaded hole rack only if threaded rack adapter brackets
are installed. The threaded rack adapter brackets are first mounted to the EIA flanges
in the rack, and then the rails are mounted into the brackets. The design of the
brackets has been optimized to limit the forward shift of the system in the rack to
only 17.3 mm.
The adapter brackets kit includes 6 brackets to accommodate different rail lengths,
plus 4 sets of custom screws in common thread sizes. A detailed ‗Getting Started
Guide' is included in the kit along with directions for installing the brackets and
mounting the rails into the brackets.
Depending on the depth of the rack used, it may be necessary to remove the server's
bezel in order to close the door of the rack. A minimum of 58 mm will be needed
between the back surface of the door panel and the front face of the EIA flange for
the front door to close with the 11G server bezel installed.

Other factors to consider when deploying the R815 include the spacing between the
front and rear mounting flanges of the rack, the type and location of any equipment
mounted in the back of the rack such as power distribution units (PDUs), and the
overall depth of the rack. See Table 16. For example, use of the CMA requires racks
that are a minimum of 1m in depth with the PDUs or other rack accessories positioned
on the sides or rear of the rack away from the CMA.
