Power Supply Replacement
Note: During normal operation, the secondary power-supply bay must have either a power supply or filler
panel installed for proper cooling.
To replace a power supply, do the following:
1. Grasp the handles located on top of the new power supply. Pivot the handles upward to 90 degrees.
This action puts the handle cams into the correct position to help seat the power supply into its
connector.
2. Carefully insert the new power supply into the power supply bay.
3. Lower the power supply release handles, carefully pressing the power supply into the connector. The
spring latch located on the underside of each handle will snap into place, indicating that the power
supply is seated correctly and locked into position.
1 Power supply 4 Fault LED (Amber)
2 Power supply handle latch 5 DC Good LED (Green)

4. Plug the power cables into the back of the power supplies.
Note: Do not connect the power cables to the power source until you are instructed to do so.
5. Replace the service access cover as described in “Service Access Cover Replacement” on page 28.
6. Reconnect the system unit to the power source.
7. Power on the system unit as described in “Starting the System” on page 25.
