FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW: How to Remove and Replace a Ultra 40 M2 Workstation Hard Drive Backplane and Signal Cable
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

Then power down the system and disconnect the Power Cord.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
This section provides procedures for removing and installing the hard drive backplane and signal cable.
On Sun Ultra 40 M2 systems, if you have a single hard drive backplane, and you are adding a second hard drive backplane
The hard drive backplane power cable is an integral part of the power supply.
The hard drive backplane power cable is an integral part of the power supply. To replace it, you must replace the power supply. Normally, this is not necessary when replacing the hard drive backplane and signal cable.

Removing the Hard Drive Backplane and Signal Cable

Sun Ultra 40 M2 systems have an optional second hard drive backplane that supports HDD4 through HDD7.
1. Power off the system, open and position the chassis, and remove the access panel.
   I. Power off and disconnect the monitor, keyboard, mouse, network connections, and any peripherals.
   II. Disconnect the power cord from the workstation.
   III. Press down the two latches on the side cover and lift the cover off the workstation.
   IV. Using both hands, place the workstation on its side.
   V. Pivot the workstation support leg underneath the workstation.
   VI. Remove the access panel:
      a. Slide the lock block to the front of the system.
      b. Press and release the two latches and lift the access panel.
   VII. Attach the antistatic wrist strap.
   VIII. If your procedure requires it, lift the fan module up and out.
   IX. Find the removal or replacement procedure you need.

2. Remove all hard drives.
3. Disconnect the hard drive signal cable from the connector of the hard drive backplane.
    # 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.
Note - P4 has a splitter; one part goes to the hard drive backplane, and the other part goes to the motherboard. Disconnect only the part that goes to hard drive backplane.
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.
Note - The hard drive power cable is part of the power supply assembly. To replace it, you must replace the power supply.
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.

Installing the Hard Drive Backplane and Signal Cable

1. Remove the new hard drive backplane and the hard drive signal cable from the packaging.
2. 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.
             o For HDD0 through HDD3, select the Master position.
             o For HDD4 through HDD7, select the Slave position.
3. If you are adding a second backplane to an Ultra 40 M2, remove the filler panel. If not, proceed to Step 4.
     a. Release the two latches by pressing them towards the front of the system.
     b. Swing the filler panel out (1) then lift it away (2).
4. Place the new hard drive backplane in the chassis so that the studs protrude through the fat end of the slots.
5. Slide the backplane toward the motherboard so that the studs hold the backplane securely in place.
6. Using a No. 2 Phillips screwdriver, replace the two screws that secure the hard drive backplane.
7. To reconnect the hard drive signal cable:
* If you are replacing the hard drive signal cable, connect one end to the connector on the hard drive backplane and the other end to the SATA0 connector on the motherboard.
Route the cable under the hard drive power cable in such a way that it will not interfere with the fan tray.
* If you are not replacing the hard drive signal cable, connect the existing cable to the connector of the hard drive backplane.
For the Ultra 40 M2:
    o HDD0 through HDD3 - J22.
    o HDD4 through HDD7 - J11.
8. Reconnect the power cable to the corresponding hard drive backplane
    # For HDD0 through HDD3, connect P3.
    # For HDD4 through HDD7, connect P4.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:Power on the system, and verify the installation.
