How to install APC NetShelter SX

Installing the NetShelter SX enclosure begins with site readiness and safety checks, followed by precise assembly and careful equipment mounting. To maximize performance, plan your rack layout around equipment dimensions, cooling capacity, and future growth. Begin by verifying floor load capacity, ensuring the installation space allows for proper clearance for service and ventilation, and confirming access to power and network connections. Unpack the enclosure and inspect all components for shipping damage before assembly. Use the included hardware and documentation to guide the process, and work with a teammate if the cabinet is heavy or complex.

• Prepare the floor and location: Ensure a level surface or use adjustable feet as needed. Verify that nearby power sources, network drops, and cooling supply are properly positioned and accessible for front and rear service access.
• Unpack and inspect: Check doors, panels, rails, and accessories for completeness. Remove protective films or coatings as appropriate and prepare mounting hardware for installation.
• Install the rails and supports: Attach the adjustable-depth rails to the cabinet body per the manufacturer’s instructions, ensuring proper alignment for front-to-back equipment installation. Secure rails firmly to the cabinet and verify smooth rail travel for eventual equipment slides or trays.
• Mount IT equipment: Slide servers, switches, storage devices, and UPS/pdu units into the rack. Use appropriate mounting screws and spacers, balancing weight evenly across rails. Route cables with careful attention to maintain access to rear ports and ventilation paths, and employ blanking panels to prevent bypass airflow.
• Configure cable management and airflow: Install vertical and horizontal cable managers as needed. Route power and data cables separately where possible to reduce interference and heat buildup. Attach door, side panels, and any optional accessories such as fans or PDU strips as required, then perform a final check of door locks and accessibility.
• Test and finalize: Close doors, verify secure locks, test equipment boot-up and network connectivity, confirm airflow is unobstructed, and label cabling for future maintenance. Document the rack layout for IT staff and service providers.
