How to use

Install the shelf into a standard 19" rack by aligning the front and rear mounting holes with the rack's vertical rails and fastening with appropriate rack screws and cage nuts. Place non-rackmount equipment centrally on the shelf to balance the load and avoid overhang. Route power and network cables to maintain clear airflow and to prevent strain on connectors. Check that the combined weight of devices does not exceed the load capacity of the rack equipment and that the shelf is secured before leaving the cabinet unattended.

Usage recommendations

For reliable performance, use the shelf for light-to-moderate weight items and distribute weight evenly. Secure heavier peripherals with additional fastening if required and avoid obstructing ventilation paths of nearby rack equipment.
