Attention: Do not allow the server to fall over.
Step 5. Remove the left-side cover (see "Removing the left-side cover" on page 193).
Step 6. Remove the existing hot-swap power supply (see "Removing a hot-swap power supply" on page
254 ).
Step 7. Touch the static-protective package that contains the hot-swap power supply to any unpainted
metal surface on the server; then, remove the power supply from the package and place it on a
static-protective surface.
Step 8. Install the new hot-swap power supply and push it in until it locks into place.
Notes:
• If only one hot-swap power supply is installed in the server, a power-supply filler must be
installed in the empty power bay.
• Do not mix power supplies with different wattage in the server.
Step 9. Route the power cord through the handle and cable tie if any, so that it does not accidentally
become unplugged.
Step 10. 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 11. 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 12. 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.
