4. Grasp the handle on the rear of the power supply and slide the power supply
forward into the power-supply bay until it clicks. Make sure that the power
supply connects firmly into the power-supply connector.
Attention: Do not mix 550-watt, 750-watt or 900-watt power supplies in the
server.
5. Route the power cord through the handle and cable tie if any, so that it does
not accidentally become unplugged.
6. Connect the power cord for the new power supply to the power-cord
connector on the power supply.
7. Connect the other end of the power cord to a properly grounded electrical
outlet.
8. 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.
9. If you are replacing a power supply with one of a different wattage in the
server, apply the new power information label provided 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.
10. 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.
