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 R450 supports both sliding rails and static rails. Both rails have a slim rail design that supports the wide system chassis.
Sliding Rails
Stab-in/Drop-in sliding rails: The Stab-in/Drop-in sliding rail also provides tool-less support for 4-post racks with square or
unthreaded round mounting holes including all generations of Dell racks. Additionally, these rails offer tool-less support for
4-post threaded racks with no conversion required.
The optional cable management arm (CMA) can be mounted on either the left or right side of the sliding rails without the use of
tools for fast and easy deployment.
