Rails; Figure 27. Empty Enclosure In A Rack - Dell PowerEdge M1000e Technical Manual

When properly installed in a rack, the enclosure sits on a sturdy pair of rails and is held in place by
four thumbscrews.
The RapidRails static rail system for the M1000e provides tool-less support for racks with square
mounting holes including all generations of Dell racks except for the 4200 and 2400 models. Also
available are the VersaRails static rails, which offer tooled mounting support for racks with square or
unthreaded round mounting holes. Both versions include a strain relief bar and cable enumerator
clips to help manage and secure the cables exiting the back of the system.
