43 PowerEdge R720 and R720xd Technical Guide
9 Rack rails and cable management
The rack rail systems for the Dell PowerEdge R720 and R720xd provide tool-less 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.
Sliding and static rail systems
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 CMA.
