- Use the cam handle to slide the power supply out of the system.
When removing a power supply, always use two hands to support its weight.
- Repeat the preceding steps for any remaining power supplies.
- 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.
Do not use excessive force when sliding the power supply into the system; you can damage the connector.
- Push firmly on the power supply cam handle to seat it all the way into the chassis, and then push the cam handle to the closed position, making sure that the cam handle release latch clicks into its locked position.
- Reconnect the power cord and secure it to the power supply using the power cord locking mechanism.
Only connect the power cord to the power supply; do not connect the power cord to a power source at this time.
