15 Rack Information

Overview

15.1
The ReadyRails™ sliding and static rail systems for the R310 provide tool-less support for 4-post racks with
square or unthreaded round mounting holes including all generations of Dell racks. Both support tooled
mounting in 4-post threaded racks (an optional adapter brackets kit is required for the sliding rails), with
the static rails also providing tooled mounting support for 2-post (Telco) racks for added versatility. 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.
NOTE: The R310 is not compatible with any other Dell rails including previous generation rails, but it does
use the same sliding rails as the R410 and uses the same static rails as the R310 & R410.

15.2
The rail offerings for the R310 consist of two types: sliding and static.
The sliding rails allow the system to be fully extended out of the rack for service and are available with or
without the optional cable management arm (CMA).
Sliding rail kits 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 sliding 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.
