DellPowerEdge R410 Technical Guide 3514 Rack Information14.1 OverviewThe ReadyRails™ sliding and static rail systems for the R410 provide tool-less support for 4-post rackswith square or unthreaded round mounting holes including all generations of Dell racks. Both supporttooled mounting in 4-post threaded racks (an optional adapter brackets kit is required for the slidingrails), with the static rails also providing tooled mounting support for 2-post (Telco) racks for addedversatility. The optional cable management arm (CMA) can be mounted on either the left or rightside 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 itdoes use the same sliding rails as the R310 and uses the same static rails as the R210 and R310.14.2 RailsThe 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 availablewith or without the optional cable management arm (CMA).Figure 7. R410 Sliding Rails with Optional CMASliding rail kits can be used in a threaded hole rack only if threaded rack adapter brackets areinstalled. The threaded rack adapter brackets are first mounted to the EIA flanges in the rack, andthen the sliding rails are mounted into the brackets. The design of the brackets has been optimizedto limit the forward shift of the system in the rack to only 17.3 mm.
