guides of the shelf. Make sure that the guiding module of shelf and blade are aligned

you feel resistance. Continue to push the blade gently until the blade connectors engage.

If you feel that you need an abnormal amount of force during blade insertion into the slot,
please extract the blade, then carefully inspect the blade and slot for problems to prevent
damage.
