Installing the microprocessor 2 expansion board

Use this information to install the microprocessor 2 expansion board

Read the safety information in Safety and Installation guidelines.

If you are replacing a server component in the server, you need to turn off the server and peripheral devices, and disconnect the power cords and all external cables.

To install the microprocessor 2 expansion board, complete the following steps.

1. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
   Attention

   Do not allow the server to fall over.
2. Unlock and remove the left-side cover (see Removing the left-side cover).
3. Remove the air baffle (see Removing the air baffle).
4. Remove the fan cage assembly (see Removing the fan cage assembly).
5. Touch the static-protective package that contains the microprocessor 2 expansion board to any unpainted metal surface on the server; then, remove the microprocessor 2 expansion board from the package.
6. Install the microprocessor 2 expansion board side bracket.
   1. Align the side bracket with the holes on the chassis and install the side bracket on the system board.

   2. Slide the side bracket toward the rear of the server.
   3. Fasten the thumbscrew on the side bracket.
7. Install the two guide pins on the system board.

    Note

    1. Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.
    2. Make sure that none of the server cables are caught under the microprocessor 2 expansion board.
13. Rotate the release lever toward the front of the server to secure the microprocessor 2 expansion board in place.
    Figure 8. Rotate release lever to the front
    
    
    Note

    Press the microprocessor 2 expansion board connector to make sure the connector is seated securely on the system board.
14. Fasten the two thumbscrews on the release lever.
15. Route the power cable to the microprocessor 2 expansion board power connector from the power paddle card.
    Figure 9. Route the power cable
    
    
16. Install any of the following components that you removed from the microprocessor 2 expansion board:

    • Microprocessor and heat sink (see Installing a microprocessor and heat sink)

    • DIMMs (see Installing a DIMM)

    • Adapters (see Installing an adapter)

17. Reconnect any cable to the microprocessor 2 expansion board that you disconnected during removal (see System-board internal connectors and Internal cable routing and connectors).
    Figure 10. Connect the power cable
    
    
    Note

    1. Connect the power cable to the microprocessor 2 expansion board power connector from the power paddle card.
    2. You might need to install the air baffle before connecting the power cable.
18. Install the fan cage assembly (see Installing the fan cage assembly).
19. Install the air baffle (see Installing the air baffle).
20. Install the power supplies (see Installing a hot-swap power supply).
21. Install and lock the left-side cover (see Installing the left-side cover).
22. Stand the server back up in its vertical position.

If you have replaced a server component or installed an optional device in the server, you need to reconnect the power cords and all external cables, and turn on the server and peripheral devices.
