Tip To prevent a loss of input power, ensure the total maximum load on each circuit supplying the switch is within the current ratings of the wiring and breakers.
Connection Guidelines for AC-Powered Systems
Follow these basic guidelines for connecting the Cisco MDS 9020 Fabric Switch AC power supply to the site power source.
•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.
Supported Power Cords and Plugs
A separate power cord is provided for each power supply. Standard power cords or jumper power cords are available for connection to a power distribution unit having IEC 60320 C13 outlet receptacles. The jumper power cords, for use in cabinets, are available as an option instead of the standard power cords.
Power Cords
The standard power cords have an IEC C15 connector on the end that plugs into the switch. The optional jumper power cords have an IEC C15 connector on the end that plugs into the switch, and an IEC C14 connector on the end that plugs into an IEC C13 outlet receptacle.
Note Only the standard power cords or jumper power cords provided with the switch are supported.
