Installing an AC Power Supply
You can replace one power supply while the other one provides power to the switch.
Before you begin
• The power supply that you are installing must be capable of using the same airflow direction as the fan
• An AC power source must be within reach of the power cable that will be used with the replacement
• There must be an earth ground connection to the chassis that you are installing the replacement module.

power supply. If you are using n+n power redundancy, there must be a separate power source for each
