DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Sun Ultra 40 Product Knowledge/Training

TIME ESTIMATE: 60 minutes

*FIELD ENGINEER INSTRUCTIONS*

PROBLEM OVERVIEW:
Disk Backplane failure.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?
Application software should be shutdown and the system in power off state.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

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

2. Remove all hard drives.

3. Disconnect the hard drive signal cable from the connector of the hard drive backplane.
For the Ultra 40, it is connector J4.
For the Ultra 40 M2:
     ■ HDD0 through HDD3 – J22.
     ■ HDD4 through HDD7 – J11.

4. Disconnect the power cable from the corresponding hard drive backplane.
     ■ For HDD0 through HDD3, disconnect P3.
     ■ For HDD4 through HDD7, disconnect P4.

5. Using a No. 2 Phillips screwdriver, remove the two screws that secure the hard drive backplane.

6. If you are replacing the hard drive signal cable, disconnect it from the SAT0 connector on the motherboard.

7. Slide the hard drive backplane toward the back of the system (toward the motherboard) until the studs protrude through the wide side of the mounting slots.

8. Lift the hard drive backplane out and away from the chassis.

9. Remove the new hard drive backplane and the hard drive signal cable from the packaging.

10. Verify that the master/slave switch is in the correct position.
     a. Flip the backplane over.
     b. Verify that the switch is in the correct position, and correct it if it is not.
          ■ For HDD0 through HDD3, select the Master position.
          ■ For HDD4 through HDD7, select the Slave position.

11. Place the new hard drive backplane in the chassis so that the studs protrude through the fat end of the slots.

12. Slide the backplane toward the motherboard so that the studs hold the backplane securely in place.

13. Using a No. 2 Phillips screwdriver, replace the two screws that secure the hard drive backplane.

14. Reconnect the hard drive signal cable.

15. Reconnect the power cable to the corresponding hard drive backplane.

16. Inspect the cabling to verify that the signal and power cables are both secure at the backplane and that the signal cable is secure at the motherboard.

17. Replace any hard drives.

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