39 PowerEdge R620 Technical GuideThe static rails (shown in Figure 11) support a wider variety of racks than the sliding rails but do notsupport serviceability in the rack and are therefore are not compatible with the CMA.Figure 11. Static railsOne key factor in selecting the proper rails is identifying the type of rack in which they will beinstalled. Both the sliding rails and the static rails support tool-less mounting in 19”-wide, EIA-310-Ecompliant square hole and unthreaded round hole 4-post racks. Both also support tooled mountingin threaded-hole 4-post racks, but only the static rails, as the more universal solution, supportmounting in 2-post (Telco) racks.Table 24 lists the rack rail systems that the R620 supports. The R620 is not compatible with anyother Dell rails or CMAs, including previous generation rails.Table 24.

Due to their reducedcomplexity and lack of need for CMA support, the static rails offer a greater adjustability range and asmaller overall mounting footprint than the sliding rails.For detailed information about static and sliding rails, see the Rack rail specifications section inAppendix A.
