The sliding and static rail systems for the Dell PowerEdge R420 provide toolless support for 4-postracks with square or unthreaded round mounting holes. Both rail systems also support tooledmounting in 4-post threaded racks, and the static rails support tooled mounting in 2-post (Telco)racks as well for added versatility.Compared to the R410 sliding rails that required the use of adapter brackets, the sliding rails for theR420 now offer support for threaded hole racks with the ReadyRails II mounting interface. Theoptional cable management arm (CMA) can be mounted on either the left or right side of the slidingrails without the use of tools for fast and easy deployment.The R420 supports both sliding rails and static rails. Both rails have a new slim rail design thatsupports the wide system chassis. The rails ship in the toolless mounting configuration, but can beconverted to the tooled configuration very quickly and easily.Sliding rails include a self-adjusting feature to allow the rails to be shared across multiple systemsand accommodate various chassis depths. The sliding rail system allows you to fully extend theserver out the rack for easy access for service. The sliding rails are available with or without theoptional CMA. Figure 8 shows the sliding rails with the CMA.
