Removing the system board

1. Read the safety information in Safety and Installation guidelines.
2. Turn off the server and all peripheral devices; then, disconnect the power cords and all external cables.
3. 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.
4. Remove the side cover (see Removing the side cover).
5. Remove the air duct.
6. Remove the microprocessor and heat sink (see Removing the microprocessor and heat sink).
   Attention

   Remove the socket covers from the microprocessor sockets on the new system board and place them on the microprocessor sockets of the system board you are removing.
7. Pull the drive cage half out of the chassis.
   
   
8. Disengage the cables from any retention-clips.
9. Note where each cable is connected; then, disconnect all cables from the system board.
   Attention

   Disengage all latches, release tabs or locks on cable connectors when you disconnect all cables from the system board. Failing to release them before removing the cables will damage the cable sockets on the system board. The cable sockets on the system board are fragile. Any damage to the cable sockets may require replacing the system board.
10. Remove any of the following components (in addition to others that might not be listed) that are installed on the system board and put them in a safe, static-protective place:
    • Adapters (see Removing a ServeRAID adapter).
    • DIMMs (see Replacing a memory module).
    • Battery (see Removing the system battery).
11. Remove the seven screws that secure the system board to the chassis.
    
    
12. Carefully lift the system board out of the server.
13. If you are instructed to return the system board, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
    Attention

    Make sure to place the socket covers for the microprocessor sockets on the system board before returning the system board.

To remove the system board on the 5U server model with hot-swap power supplies (Model name: 2582-F4x), complete the following steps. For 4U server models with non-hot-swap power supplies, please see the above sub-section.

1. Read the safety information in Safety and Installation guidelines.
2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
3. Unlock and remove the side cover (see Removing the side cover).
4. Carefully turn the server on its side so that it is lying flat, with the system board facing up.
   Attention

   Do not allow the server to fall over.
5. Rotate the rear adapter-retention bracket to the open (unlocked) position.
6. Remove the hard disk drive fan duct (see Removing the hard disk drive fan duct).
7. Remove the microprocessor and heat sink (see Removing the microprocessor and heat sink).
   Attention

   Remove the socket covers from the microprocessor sockets on the new system board and place them on the microprocessor sockets of the system board you are removing.
