Step 6. Make sure that the on/off switch of the new power supply is in the Off position.
Step 7. Using both hands, support and align the edges of the power supply with the opening in the system
chassis, and then gently push the power supply into the chassis using the cam handle. The power
supplies are keyed and can only be installed one way.
Attention: Do not use excessive force when sliding the power supply into the system. You can
damage the connector.
Step 8. Close the cam handle so that the latch clicks into the locked position and the power supply is fully
seated.
Step 9. Reconnect the power supply cabling:
a. Reconnect the power cable to the power supply and the power source.
b. Secure the power cable to the power supply using the power cable retainer.
Step 10. Turn on the power to the new power supply, and then verify the operation of the power supply
activity LEDs. The power supply LEDs are lit when the power supply comes online. The amber fault
LED should be off and the DC good light should be on for each power supply.
