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: Push the chassis forward until it cannot slide and make sure that the
screws are securely installed to complete the installation.

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.
