System I/O board replacement (trained technicians only)

Use this section to remove and install the system I/O board from the system board assembly.


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

When the server has a Liquid to Air Module (L2AM) installed, you must apply for a L2AM module handle (L2AM heat sink bracket) first if you need to install or remove the system board assembly or processor. However, while replacing the old L2AM with a new one, you do not need to apply for a module handle (L2AM heat sink bracket) as the new L2AM package contains it.
