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.

The adjustment range of the rails is a function of the type of rack in which they are being mounted. The min-max values listed below represent the allowable distance between the front and rear mounting flanges in the rack.

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).
