Dell PowerEdge R720 User Manual

44 PowerEdge R720 and R720xd Technical Guide
The static rails (shown in Figure 15) support a wider variety of racks than the sliding rails, but do not
support serviceability in the rack and are not compatible with the CMA.
Figure 15. Static rails
One key factor in selecting the proper rails is identifying the type of rack in which they will be
installed. Both the sliding rails and the static rails support tool-less mounting in 19”-wide, EIA-310-E
compliant square hole and unthreaded round-hole 4-post racks. Both also support tooled mounting
in threaded hole 4-post racks, but only the static rails, as the more universal solution, support
mounting in 2-post (Telco) racks.
Table 23 lists the rack rail systems that the R720 and R720xd support.
