how to install Middle Atlantic Custom Shelf

• Prepare the rack: Ensure your 19\" rack rails are installed and aligned. Confirm the rack is clean and free of debris to prevent mounting hardware from binding.
• Position the shelf: Slide the 4U shelf into the desired vertical position between the rack rails. Align the face opening with the component’s front panel to ensure a neat, flush fit once seated.
• Secure the shelf: Use the appropriate mounting hardware (screws/bolts) compatible with your rack rails. Fasten the shelf securely to the front and rear rails to minimize vibration and movement during operation.
• Install the component: Place the equipment so its front face aligns with the shelf’s cutout. The design (RSH) provides a precise opening that accommodates the component’s face while delivering a clean, integrated appearance.
• Route cabling and finalize: Attach any needed cables, ensuring clear pathways for airflow and accessibility. Confirm clearance at the rear to avoid interference with rear-mounted connectors or cabling. Close up the rack and test for accessibility.

Frequently asked questions

• What does 4U mean for this shelf? The 4U height corresponds to a standard 7.0 inches of rack space, providing a stable mounting area for mid-sized equipment while keeping the footprint consistent with standard 19\" racks.
• How deep is 11.5 inches, and what equipment fits? The 11.5\" depth accommodates a broad range of devices, including larger modular units, power distributors, and stacked modules. It is ideal for components that require more rear clearance for connectors and cabling.
