Note: When you push the chassis forward, you will hear a snapping sound. If you
can’t push it, you need to pull down the buckle of the inner rail to continue to push
the chassis gently.
Step 5: When the chassis is pushed forward and cannot slide, the screws are firmly
installed and the installation is complete

Note: During equipment maintenance, it is necessary to loosen the panel screws and
pull the chassis lightly. Do not push or pull the chassis at random speed to avoid
damage to the equipment.
