Rack, rails, and cable management
Key factors in selecting the proper rails include, Identifying:
● Type of rack in which the rails will be installed
●
Spacing between the front and rear mounting flanges of the rack
● Type and location of any equipment mounted on the rear of the rack such as power distribution units (PDUs), and the overall
depth of the rack
Reference the DellEMC Enterprise Systems Rail Sizing and Rack Compatibility Matrix for the following information:
● Specific details about rail types and their functionalities
● Rail adjustability ranges for various rack mounting flange types
● Rail depth with and without cable management accessories
● Rack types supported for various rack mounting flange types
Topics:
• Rails information
• Cable Management Arm
• Strain Relief Bar
Rails information
The R750xs supports both sliding rails and static rails. Both rails have a slim rail design that supports the wide system chassis.
Sliding rails
The sliding rails, shown in the figure below, allow the system to be fully extended out of the rack for service. The sliding rails
have a Cable Management Arm (CMA) and a Strain Relief Bar (SRB) option.
There are two types of sliding rails available:
● Ready Rails II sliding rails
● Stab-in/Drop-in sliding rails
B21 Ready Rails II sliding rails for 4-post racks
● Supports Drop-in installation of the chassis to the rails
● Supports tool-less installation in 19-inch EIA-310-E compliant square or unthreaded round hole 4-post racks including all
generations of Dell racks
● Supports tooled installation in 19-inch EIA-310-E compliant threaded hole 4-post racks
● Supports full extension of the system out of the rack to allow serviceability of key internal components
● Supports optional Cable Management Arm (CMA)
● Supports optional Strain Relief Bar (SRB)
