The rack rail systems for the Dell™ PowerEdge™ R720 and R720xd provide toolless support for 4-post racks with square or unthreaded round mounting holes, including all generations of Dell racks. Compared to the predecessor R710 sliding rails that required the use of adapter brackets, the sliding rails for the R720 and R720xd now offer native support for threaded-hole racks with the new ReadyRails™ II mounting interface. 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. The R720 and R720xd support both sliding rails and static rails. Both rails have a new slim rail design that supports the wide system chassis. The sliding rails (shown in Figure 14) 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). 39 PowerEdge R720 and R720xd Technical Guide

The rack rail systems for the
Dell™ PowerEdge™
R720 and R720xd provide toolless support for
4-post racks with square or unthreaded round mounting holes, including all generations of Dell
racks. Compared to the predecessor R710 sliding rails that required the use of adapter brackets, the
sliding rails for the R720 and R720xd now offer native support for threaded-hole racks with the new
ReadyRails
™
II mounting interface.
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.
The R720 and R720xd support both sliding rails and static rails. Both rails have a new slim rail design
that supports the wide system chassis.
The sliding rails (shown in Figure 14) 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).
