Replacing the Motherboard

This section describes removal and installation of the motherboard.

Removing the Motherboard

The motherboard, CPU, and NVRAM are a single replaceable unit.

1. Power off the system and attach an antistatic wrist strap. Disconnect all external cables; open and position the chassis, and remove the access panel.

2. If necessary, remove all the PCI cards and DIMMs. Set these components onto an antistatic mat

3. Remove the fan tray.

4. (Optional) If you want to use the same Ethernet address and system ID for the new motherboard, remove the NVRAM and place it on an antistatic mat.

Note - If you have software that is licensed to the HostID or Ethernet address, you should install the old NVRAM on the new motherboard.

5. Remove all cables from the cable clips

6. Disconnect the following power and signal cables from the motherboard.

  - I/O module signal and power cable at connector J3

  - I/O module USB cable at connector J36

  - DVD-dual drive cable at connector J11

  - Fan tray backplane cable at connector J20

  - Power supply cables at connectors J22, J28, J45 (P1, P2, and P5)

  - Hard drive signal cable connector J42

7. Turn the motherboard latch 90 degrees counterclockwise

8. Move the cables out of the way.

9. Using the motherboard handles, tilt the motherboard to one side and lift it until it is free of the chassis

10. Set the motherboard down onto the antistatic mat.

Installing the Motherboard

1. Remove the new motherboard from its antistatic package and place it on an antistatic mat.

2. Move all cables out of the way.

3. Align the motherboard rear panel connectors with the matching holes in the rear panel 

4. Gently lower the motherboard while tilting it down 

5. Align the motherboard so that the hooks fit into the holes of the motherboard tray.

Caution - Ensure that the hooks are located in the holes. Improper alignment can damage the motherboard.

6. Turn the motherboard latch 90 degrees clockwise to secure the motherboard.

 - Ensure that the motherboard connector panel aligns with the chassis rear panel.

7. Connect the cables to the corresponding motherboard connectors

  - I/O module signal and power cable at connector J3

  - I/O module USB cable at connector J36

  - DVD-dual drive cable at connector J11

  - Fan tray backplane cable at connector J20

  - Power supply cables at connectors J22, J28, J45 (P1, P2, and P5)

  - Hard drive signal cable connector J42

8. Secure the cables into the cable clips

9. If necessary, install the old NVRAM onto the new motherboard.

Note - If you have software that is licensed to the HostID or Ethernet address, you should install the old NVRAM on the new motherboard.

10. Install the PCI cards and the DIMMs

11. Inspect the motherboard to verify that:

  - Cable connections are tight and cable clips are secured.

  - DIMMs are properly installed.

  - NVRAM is tight in the socket.

  - PCI cards are properly seated and secured.

12. Reassemble the workstation, power on the system, and verify the motherboard installation.
