FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW: How to Remove and Replace a Ultra 40 M2 Workstation Motherboard
- 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:

Removing the Motherboard Tray Assembly

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. Disconnect all external cables from the back panel.
3. If necessary, remove the PCI cards.
      Remove a PCI Card
      I. If there is an auxiliary PCI card power cable, disconnect it from the PCI card.
      II. Using a No. 2 Phillips screwdriver, remove the screw that secures the PCI card retainer to the chassis rear panel.
          Caution - If you are removing a graphics accelerator from a PCI Express connector, ensure that you release the PCI-X connector latch
      III. Gently rock the PCI card forward, then lift it straight out of the PCI card slot, and place it aside on an antistatic mat.
      IV. If you are not installing another PCI card in the empty slot:
            a. Insert a filler panel into the rear panel slot: The rear panel slot must be closed with a filler panel to meet system EMI and airflow requirements
            b. Install the side cover and the access panel, power on the system, and verify the installation.

4. Disconnect the following power and signal cables from the corresponding motherboard connectors and set them out of the way of the motherboard.
   J4 : FP1 - Connection from the front I/O board (power on, LED blink, audio, etc)
   J24 : GFX2_PWR_IN - connection from P4 of the power supply
   J26 : GFX1_PWR_Out - goes to PCIe slot if Graphics card needing supplemental power is installed
   J30 : GFX2_PWR_out - goes to PCIe slot if Graphics card needing supplemental power is installed (for second card)
   J33 : Fan - Power for fan backplane
   J11 : SATA2 from the second HDD backplane (HDD4 to HDD7) (optional)
   P1 and P2 : Power for motherboard
   J47 : Ribbon cable with signal to DVD
   J22 : SATA1 from first HDD backplane for HDD0 to HDD3
   J56 : FP2 - Second cable from the front I/O board
   J60 : FP2 - Third cable from the front I/O board

5. Turn the motherboard latch 90 degrees counterclockwise.
6. Move the cables out of the way.
7. Using the handles on the tray assembly, tilt the motherboard to one side and lift it until it is free of the chassis.
8. Place the motherboard on an antistatic mat.

Installing the Motherboard Tray Assembly

1. Remove the new motherboard tray assembly from its antistatic package and place it on an antistatic mat.
2. Move all cables out of the way.
3. Align the tray assembly's rear panel connectors with the matching holes in the rear panel.
4. Gently lower the tray assembly while tilting it down.
5. Align the tray assembly so that the hooks fit into the holes of the tray.
Caution - Ensure that the hooks are located in the holes. Improper alignment might damage the motherboard.
6. Turn the tray assembly latch 90 degrees clockwise to secure the motherboard.
7. Connect the cables to the corresponding motherboard connectors.
8. Install the PCI cards.
9. Inspect the motherboard to verify the following:
    All cable connections are tight and cable clips are secured.
    All cables are routed correctly, where they will not interfere with other equipment.
Caution - Take particular care to ensure that cables will not interfere with or get tangled in the fan tray.
    DIMMs are installed properly.
    PCI cards are seated and secured properly.
    If you have a graphics accelerator with a power cable, ensure that the power cable is connected to the motherboard.
10. Install the side cover and the access panel, power on the system, and verify the installation.
