To install a hot-swap ac power supply, complete the following steps:
Step 1. Read the safety information that begins on "Safety" on page v and "Installation guidelines"
on page 34.
Step 2. 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 3. 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.
Step 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 install power supplies of different watt in the server.
Step 5. Route the power cord through the handle and cable tie if any, so that it does not accidentally
become unplugged.
Step 6. Connect the power cord for the new power supply to the power-cord connector on the power
supply.
Step 7. Connect the other end of the power cord to a properly grounded electrical outlet.
Step 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.
Step 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.
