14 Rack Information

14.1 Overview

The ReadyRails™ static rail systems for the R210 II provide toolless support for racks with square or unthreaded round mounting holes including all generations of Dell racks. The rail systems also offer tooled mounting support for 4-post threaded and 2-post (Telco) racks for added versatility. See Table 17 for the list of supported rails and racks.

14.2 Rails

Two different static rail systems are available for the R210 II: the A4 rail system and the A6 rail system. Both support toolless mounting in 19‖-wide, EIA-310-E compliant square hole and unthreaded round hole racks using the ReadyRails™ mounting interface. Both also support a generic mounting interface for tooled mounting in threaded hole and 2-post (Telco) racks. Screws are not included in either kit because threaded racks are offered with a variety of thread designations.

The A6 rail system also supports a cantilever (ear) mounting option, although it is not recommended since it does not support shipment of the server in the rack and allows the position of the server to exceed its designated U-space.

The key difference between the A4 and A6 rail systems is the overall length of the rail members. The A6 rail system, which is the default rail system being offered with the R210 II, is the shorter of the two and is well suited for mounting in 2-post racks or in 4-post racks with mounting flanges that are spaced in the 500-760 mm range. The A4 rail system is longer and can be used for mounting in 4-post racks with mounting flanges that are spaced in the 600-890 mm range. See Table 18 for specific adjustment range information on each rail system.
