13 Rack Information

13.1 Overview

The ReadyRails™ static rail system for the R210 provides tool-free support for racks
with square or unthreaded round mounting holes (including Dell's 42xx and 24xx series
racks) with an adjustment range of 60–87 cm. The rails also offer tooled mounting
support for 4-post threaded and 2-post (Telco) racks for added versatility.

13.2 Rails

The static rails for the R210 support tool-less mounting in 19"-wide, EIA-310-E
compliant square hole and unthreaded round hole racks via Dell's ReadyRails™
mounting interface. The rails also support a "generic" mounting interface for tooled
mounting in threaded hole and 2-post (Telco) racks. Screws are not included in the kit
since threaded racks are offered with a variety of thread designations. Users must
provide their own screws when mounting the rails in threaded or 2-post racks.

13.3 Cable Management Arm (CMA)

The static rails for the R210 support a wide variety of racks and mounting
configurations but do not support the ability to extend the system out of the rack for
service. Thus, they do not provide support for a cable management arm (CMA).
