Eaton Tripp Lite Series 25U SmartRack Expansion Enclosure — Standard-Depth Half-Height, No Side Panels

Meet a scalable backbone for data center deployments with the Eaton Tripp Lite Series SR25UBEXP SmartRack expansion enclosure. Designed to be paired with adjacent cabinets in bayed rows, this 25U SmartRack expansion model provides a streamlined path to modular, efficient cooling and cabling, while keeping the front doors and roof in place for security and protection. With integrated baying tabs and a no-side-panel design, it’s the ideal expansion enclosure for high-density environments that demand rapid scalability and clean, organized rack layouts. Built for hot aisle/cold aisle configurations, this enclosure helps optimize airflow and cooling efficiency without sacrificing accessibility or serviceability.

• Modular baying compatibility: Specifically built as an expansion version for use in bayed arrays. Integrated baying tabs simplify aligning multiple enclosures in straight rows, reducing installation time and ensuring consistent alignment across the entire rack row.
• No side panels, doors and roof included: The SR25UBEXP ships with front and rear door access plus a roof, providing security and environmental protection for equipment while omitting side panels to facilitate rapid row installation and clean cable management in tight data-center aisles.
• 25U capacity in a standard-depth, half-height footprint: Ideal for modular data centers and dense deployments, offering ample rack space without overwhelming floor space. Its half-height design is optimized for stacking in bayed configurations while preserving front-to-back access for maintenance and upgrades.
• Hot aisle / cold aisle readiness: Engineered to support efficient cooling strategies, with ventilation designed to support cold- and hot-aisle separation. This enclosure helps improve airflow to critical equipment and reduces energy consumption in dense rack rows.
• Durable construction with practical access: Built from robust materials with a dependable finish to withstand the rigors of data center use. The enclosure is designed for straightforward serviceability, cable routing, and equipment installation, offering durable protection without compromising accessibility.

How to install Eaton Tripp Lite Series 25U SmartRack Expansion Enclosure

Step 1: Plan your bay layout. Confirm the number of adjacent cabinets required, the aisle width, and the cooling strategy to ensure consistent airflow across the row.

Step 2: Inspect and prepare. Unpack the SR25UBEXP and verify that the doors, roof, and baying tabs are intact. Clear the installation area of obstacles and ensure floor load capacity meets the data center requirements.

Step 3: Position and align. Place the expansion enclosure in the planned bay location adjacent to existing SmartRack enclosures. Use the integrated baying tabs to align with neighboring cabinets, ensuring a seamless row with consistent gaps and clear front/back access.

Step 4: Secure and anchor. Fasten the enclosure per your data center’s mounting standards or supplier guidelines. Ensure proper anchoring to the floor or adjacent cabinets to maintain rigidity within the bayed row.

Step 5: Install doors and roof. Attach the front and rear doors, then install the roof for top protection. Verify that door hinges operate smoothly and that there is adequate clearance for maintenance access and cable routing.

Step 6: Cable management and equipment installation. Route power and data cables through the enclosure’s cable openings, cable management accessories, and rear compartments as needed. Position equipment inside 25U space, leveraging the standard mounting rails and fans if available, and ensure proper airflow paths in accordance with your hot aisle/cold aisle plan.

Step 7: Final checks. Confirm that the bayed row aligns with neighboring enclosures, doors close securely, and there is no interference with airflow or cable runs. Document the setup and perform a basic power-on test to verify that all devices power up correctly within the configured rack.

Frequently asked questions

• Q: What is the SR25UBEXP best used for? A: It is an expansion enclosure designed to be placed in bayed rows alongside other SmartRack enclosures. It adds 25U of rack capacity while providing doors and a roof for protection and security, and it supports streamlined multi-cabinet configurations.
• Q: Does the SR25UBEXP include side panels? A: No side panels are included, aligning with its purpose as part of a bayed row where side panels are typically not required for each unit in the lineup. Doors and a roof are included.
• Q: Is this enclosure compatible with hot aisle/cold aisle cooling? A: Yes. The design supports hot aisle/cold aisle configurations to optimize airflow and cooling efficiency in dense data center environments.
• Q: How many U does the enclosure hold? A: It holds 25U, making it suitable for a broad range of servers and equipment while keeping a compact footprint in standard-depth installations.
• Q: Can I use this enclosure on its own, or must it be part of a bayed row? A: It is intended as an expansion enclosure for bayed rows, but it can be used as part of a standalone setup if a single cabinet is needed in a given space. Its primary strength is when used in conjunction with other SmartRack enclosures.
• Q: What kind of maintenance or upgrades does it support? A: The enclosure provides accessible front and rear doors, roof access, and integrated baying tabs for easy alignment. This supports routine maintenance, cable management updates, and equipment upgrades without dismantling entire rows.
