System I/O board replacement (trained technicians only)

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 an L2AM module (Closed loop cooling module) installed, you must apply for a handle (L2AM heat sink bracket) first if you need to install or remove the processor board, I/O board, processor and PIB board. However, while replacing the old L2AM module with a new one, you do not need to apply for a handle (L2AM heat sink bracket) as the new L2AM module contains it.
