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.

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.
