become unplugged.
Step 6. Connect one end of the power cord for the new power supply into the connector on the back of the
power supply; then, connect the other end of the power cord to a properly grounded electrical
outlet.
Note: If the server has been turned off, you must wait approximately 3 minutes after you connect
the server power cord to an electrical outlet before the power-control button becomes active.
Step 7. Make sure that the ac power LED and the dc power LED on the ac power supply are lit, indicating
that the power supply is operating correctly. The two green LEDs are to the right of the power-cord
connector.
Step 8. If you are replacing a power supply with one of a different wattage, apply the power information
label provided with the new power supply over the existing power information label on the server.
Power supplies in the server must be with the same power rating or wattage to ensure that the
server will operate correctly.
Step 9. If you are adding a power supply to the server, attach the redundant power information label that
comes with this option on the server cover near the power supplies.
