Cable Management Arm - Dell PowerEdge R620 Technical Manual

The rack rail systems for the Dell™ PowerEdge™ R620 provide toolless support for 4-post racks
with square or unthreaded round mounting holes. Compared to the R610 sliding rails that required
the use of adapter brackets, the sliding rails for the R620 now offer support for threaded hole racks
with the 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 R620 supports both sliding rails and static rails. Both rails have a new slim rail design that
supports the wide system chassis. The rails ship in the toolless mounting configuration, but can be
converted to the tooled configuration very quickly and easily.
The sliding rails for the R620 also include a self-adjusting mechanism that accommodates both
chassis depths. The sliding rail system allows you to fully extend the server out the rack for easy
access for service. The sliding rails are available with or without the optional CMA. Figure 10 shows
the sliding rails with the CMA.
