How to install the RK4

• Plan your equipment layout: Before mounting, map out the position of each device to optimize airflow, accessibility, and cable routing. Group devices by function (signal processing, sources, power distribution) to simplify maintenance and future upgrades.
• Prepare the location: Ensure the installation space is stable, level, and free from excessive dust or moisture. Verify that the floor can support the cabinet’s weight, especially when fully loaded with gear.
• Install rack rails and mounting hardware: Attach the included rails or mounting hardware per the manufacturer’s guidelines. Confirm that rails are level and properly aligned to prevent misalignment of equipment slots and to facilitate smooth insertion of gear.
• Mount equipment: Begin with heavier devices at the bottom to lower the center of gravity. Use appropriate screws or rails to secure each unit firmly, avoiding overtightening that could damage equipment.
• Manage cables and airflow: Route power, data, and signal cables with careful bend radii and sufficient space to prevent interference. Use ties or organizers to keep cables tidy, while ensuring adequate ventilation around heat-generating components.
