NOTICE: The power supplies are hot-pluggable. The system requires one power supply to be installed for the system to operate normally. The system
is in the redundant mode when two power supplies are installed. Remove and replace only one power supply at a time in a system that is powered on.
NOTE: 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 Figure 2 -4 ).
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
" Safety First—For You and Your System " in "Troubleshooting Your System."
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
