System board replacement (trained technician only)

Follow instructions in this section to remove and install the system board.

Important
Before you return the system board, make sure that you install the CPU socket dust covers from the new system board. To replace a CPU socket dust cover:

  1. Take a dust cover from the CPU socket assembly on the new system board and orient it correctly above the CPU socket assembly on the removed system board.

  2. Gently press down the dust cover legs to the CPU socket assembly, pressing on the edges to avoid damage to the socket pins. You might hear a click on the dust cover is securely attached.

  3. Make sure that the dust cover is securely attached to the CPU socket assembly.

  4. Replacing a system board requires configuring GPU power capping value. When removing a defective system board, before powering off the server, make sure to read the GPU OAM power capping value. When installing a new system board, after powering on the server, make sure to configure the GPU OAM power capping value. Follow the instruction in GPU OAM power capping settings (trained technician only).
