Connection Guidelines for AC-Powered Systems
For connecting the Cisco MDS 9396T switch AC power supplies to the site power source, follow these basic
guidelines:
• Each power supply should have its own dedicated branch circuit.
• For international, circuits should be sized according to local and national codes.
• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment.
