how to install Eaton Tripp Lite SR45UBWD

Installing the SR45UBWD is a straightforward process that emphasizes safety, airflow, and future-ready scalability. Follow these steps to assemble and populate your wide SmartRack without sacrificing efficiency or cable organization.

• Plan your layout: Determine equipment heights, weights, and power requirements. Assess room floor load capacity and ensure a flat, level surface with adequate ventilation to support the enclosed equipment and airflow.
• Unpack and inspect: Remove packaging, verify all parts, doors, side panels, rails, and mounting accessories are present, and check for any cosmetic or structural damage before installation begins.
• Position the cabinet: Place the enclosure in the desired location, ensuring there is sufficient space for front and rear clearance for service and cooling. Use levelers or shims to guarantee the cabinet sits plumb and stable.
• Install mounting rails: Attach the 19-inch mounting rails inside the cabinet according to the manufacturer’s guidelines. Align rails with standard mounting hole pitch and adjust to the required height for your equipment, ensuring correct front-to-back spacing for airflow and cable routing.
• Mount equipment: Begin with heavier items first, such as storage arrays or switches, securing them to the rails with manufacturer-approved screws. Leave adequate space for airflow and future expansion, and route power and data cables to avoid blocking vents or obstructing fans.
• Route cables and power: Use the integrated cable management channels and side-space for PDU mounting to maintain tidy, organized cabling. Label cables for easy identification and future maintenance.
• Install side panels and doors: Reattach removable side panels and secure the front and rear doors. Ensure locking mechanisms operate smoothly and that access is controlled per your security policy.
• Finalize and test: Close all panels, verify door operation, reconnect power, and confirm that cooling airflow is unobstructed. Power on all equipment, test connectivity, and validate that PDUs distribute power correctly without overloads.
