Depending on the depth of the rack used, it may be necessary to remove the server's bezel in order to close
the door of the rack. A minimum of 58 mm will be needed between the back surface of the door panel and
the front face of the EIA flange for the front door to close with the 11G server bezel installed.

The static rails support a wider variety of racks than the sliding rails but do not support serviceability in the
rack and are thus not compatible with the CMA.

Figure 29. R310 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 mounting in 19‖-wide, EIA-310-E compliant 4-post racks,
but only the static rails, as the more generic or ―universal‖ solution, support mounting in 2-post (Telco)
racks.
