Frequently Asked Questions
What type of rails is the Cable Management Arm (CMA) compatible with?
The CMA is compatible only with sliding rails, not static rails.
How can I service the server without powering it down or disconnecting cables?
Using optional CMA procedures allows you to extend the system from the rack for service without powering down or disconnecting the cables.
What hardware is required to remove outer brackets in a shallow rack?
Use a #2 Phillips screwdriver to remove the screws that secure the brackets to the rails.
How should I route and secure cables if I am not using a CMA?
Follow specific procedures for static rails or use hook-and-loop straps to bundle and secure cables to either the left or right rail.
