Always put on an ESD wrist strap or ESD gloves before handling a board. 
Filler panels must be installed in vacant slots to ensure the device functions correctly. For example, they 
ensure electromagnetic compatibility, prevent the ingress of dust or foreign objects, and maintain proper 
airflow for heat dissipation.
Boards are fragile and valuable. Exercise caution when handling them. Use a box designed specifically 
for transporting the boards.
When installing or replacing a board, remove and re-install the corresponding filler panels only.
