Dell 13 Rack Information 13.1 Overview The ReadyRails™ sliding and static rail systems for the R410 provide toolless 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 R410 is not compatible with any other Dell rails including previous generation rails, but it does use the same sliding rails as the R310 and uses the same static rails as the R210 and R310. 13.2 Rails The rail offerings for the R410 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). Figure 25. R410 Sliding Rails with Optional 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. PowerEdge R410 Technical Guide 43
