To install an ac power supply, complete the following steps:
Procedure
1. Read the safety information that begins on page "Safety" on page v and
"Installation guidelines" on page 37.
2. Remove the power-supply blank from the empty power-supply bay by
pinching the side clip and pulling the power-supply blank from the bay. Save
the power-supply blank in case you remove the power supply at a later time.
Important: During normal operation, each power-supply bay must contain
either a power supply or power-supply blank for proper cooling.
3. Slide the ac power supply into the bay until the retention latch clicks into
place. Make sure that the power supply connects firmly into the power-supply
connector.
Attention: Do not install 460-watt and 675-watt power supplies,
high-efficiency and non-high-efficiency power supplies, or ac and dc power
supplies in the server.
4. Connect the power cord for the new ac power supply to the power-cord
connector on the power supply.
