Compared to the predecessor R710 sliding rails that required the use of adapter brackets, thesliding rails for the R720 and R720xd now offer native support for threaded-hole racks with the newReadyRails II mounting interface.The optional cable management arm (CMA) can be mounted on either the left or right side of thesliding rails without the use of tools for fast and easy deployment.Sliding and static rail systemsThe R720 and R720xd support both sliding rails and static rails. Both rails have a new slim rail designthat supports the wide system chassis.The sliding rails (shown in Figure 14) allow the system to be fully extended out of the rack for serviceand are available with or without the optional CMA.Figure 14.
