13 Rack Information
13.1 Overview
The ReadyRails™ sliding rail system for the R815 provides tool-less support for racks
with square or unthreaded round mounting holes including all generations of Dell
racks. They also support tooled mounting in 4-post threaded racks via an optional
adapter brackets kit. The optional cable management arm (CMA) can be mounted on
either the left or right side of the sliding rails without the use of tools for fast and
easy deployment. It is important to note the following:
 The R815 is not compatible with any other Dell rails including previous
generation rails, but it does use the same rails as the R715, R810, and R910.
 The R815 supports sliding rails only. Static rails are not supported.
 Mounting in 2-post racks is not supported.
 The CMA is not supported on racks that are less than 1m in depth including
Dell‘s 4200 and 2400 racks.
13.2 Rails
The ReadyRails sliding rails for the R815 support toolless mounting in 19‖-wide, EIA-
310-E compliant square hole and unthreaded round hole racks and are available with
or without the optional cable management arm (CMA). See Figure 10.
