WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Power off the system, open and position the chassis, and remove the access panel.

2. Squeeze the power supply connector clip to disconnect the following cables from the motherboard:
     ■ P1 on the motherboard
     ■ P2 on the motherboard
     ■ I2C on the motherboard
     ■ GFX2_pwr_in (Ultra 40), or GFX2_pwr_out (Ultra 40 M2)

3. Remove the hard drive power cable at connector P3.

4. If P4 is connected to the second hard drive backplane, disconnect it (Ultra 40 M2 only/optional).

5. Turn the captive screw that secures the power supply to the chassis.

6. Using the plastic handle, push the power supply out of the back of the chassis.

7. Guide the power cables out of the chassis as you push the power supply out the back of the chassis.

8. Remove the new power supply from its package.

9. Align the power supply IEC-320 connector (power cord socket) so that the socket is nearest the left rear of the chassis (left rear when viewed from the back).

10. Guide the cables and push the power supply into the chassis opening until the back of the power supply aligns with the back of the chassis.

11. Tighten the captive screw that secures the power supply to the chassis.

12. Route the cables under the hard drive signal cable, and over the DVD signal cable.

13. Connect the following cables to the motherboard:
     ■ P1 on the motherboard
     ■ P2 on the motherboard
     ■ I2C on the motherboard
     ■ GFX2_pwr_in (Ultra 40), or GFX2_pwr_out (Ultra 40 M2)

14. Connect the hard drive power cable at P3.

15. Connect the splitter on cable P4 to GFX2_pwr_in (or GFX2_pwr_out) on the motherboard.

16. If a second hard drive backplane is present, connect P4 to it (Ultra 40 M2 only/optional).

17. Inspect the power supply fasteners to verify that they are connected properly:
     ■ The power supply push bar is seated.
     ■ The power supply captive screw is tight.

18. Inspect the power supply cabling to verify that the cables are routed and connected properly.
     ■ P1 on the motherboard
     ■ P2 on the motherboard
     ■ I2C on the motherboard
     ■ GFX2_pwr_in (_out)on the motherboard
     ■ P3 to the hard drive backplane
     ■ P4 to the second hard drive if one is present (Sun Ultra 40 M2 only/optional). Otherwise, leave it unconnected.

19. If you removed any extended PCI cards to access the cables or connectors, replace them.

20. Install the side cover and the access panel, power on the system, and verify the installation.
