Frequently Asked Questions
Which PowerEdge models are recommended for cable routing procedures?
This white paper applies to systems like the R520 running with a CMA in various rack sizes (e.g., PowerEdge 4210, 4820).
Can I use the Cable Management Arm (CMA) on static rails?
No, the CMA accessory is compatible only with sliding rails, not static rails.
How should I route cables when using outer CMA brackets in a shallow rack without one?
You can remove the outer CMA brackets by using a #2 Phillips screwdriver to unscrew them from the sliding rails.
Where are data and power cables secured in a statically mounted system?
Data cables should be placed on either the left rail, and power cables should be placed on the right rail when installed on static rails.
