After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is working
properly. The power- on indicator will turn green to signify that the power supply is functioning properly (see "
Power Indicator Codes
").

Before you perform this procedure, read the safety instructions in your
System Information
document.
