When connecting the Switch to a Redundant Power Supply, an RPS cable is necessary. Please review these products for
matching cable pins.The following diagrams and tables show the standard RPS connector and their pin assignments.
NOTE: The DGS-3420-28PC and the DGS-3420-52P use the RPS-700 and not the RPS-500. Both devices
have their own cables included in the package.
