System board assembly replacement (trained technicians only)

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

Important

  • This task must be operated by trained technicians that are certified by Lenovo Service. Do not attempt to remove or install it without proper training and qualification.

  • When the server has a Compute Complex Neptune Core Module installed, you must apply for a shipping bracket FRU first if you need to install or remove the system board assembly or processor. However, when replacing the old Compute Complex Neptune Core Module with a new one, you do not need to apply for a shipping bracket FRU as the new module package contains it.
