2. If necessary, remove any long PCI cards that are blocking the cables.

- Place the PCI card on an antistatic mat.

3. Remove the fan tray.

4. Squeeze the power supply connector clip to disconnect the following cables from the motherboard:

- P2 power cable on the motherboard (J22)

- P1 power cable on the motherboard at (J28)

- P5 power supply signal cable on the motherboard (J45)

5. Disconnect the following cables from the hard drive backplane:

- P3 hard drive backplane power cable on the hard drive backplane (J2)

- Hard drive signal cable to J4 on the hard drive backplane. (This cable also serves as a cable clip over other cables).

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

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

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

- Set the power supply aside on an antistatic mat.

Installing the Power Supply

1. Remove the new power supply from its package.

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

3. 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.

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

5. Connect the following cables:

- P1 power cable on the motherboard at (J28)

- P2 power cable on the motherboard (J22)

- P3 hard drive backplane power cable on the hard drive backplane (J2)

- P5 power supply signal cable on the motherboard (J45)

- Hard drive signal cable to J4 on the hard drive backplane. (This cable also serves as a cable clip over other cables).

6. Inspect the power supply fasteners to verify that:

- The power supply push bar is seated.

- The power supply captive screw is tight.

7. Inspect the power supply cabling to verify that:

- The three power supply cables are firmly connected to the motherboard at P1, P2, and P5 (J45).

- The hard drive backplane power cable is firmly connected at J4.

- The hard drive backplane signal cable is securely connected at both ends and is routed over the other cables.

8. Install the fan tray.

9. If you removed any PCI cards, re-install them.
