Eaton SR45UB 45U Rack Enclosure Cabinet 42in Depth

Overview :

The Eaton SR45UB is a 45U floor-standing rack enclosure designed for housing servers, network equipment, and power infrastructure in structured IT environments. It is deployed by data center engineers, network architects, and infrastructure teams requiring a secure and standardized rack platform for equipment installation.

This enclosure supports standard 19-inch rack equipment with a total capacity of 45U and a high static load rating of up to 3500 lbs (1588 kg). It features four adjustable vertical mounting rails with square-hole (EIA-310-E compliant) openings, allowing flexible mounting depth adjustments to accommodate various server and UPS chassis sizes. The cabinet includes perforated front and rear doors to support front-to-rear airflow required for active cooling systems.

The SR45UB is typically deployed in data centers, MDF rooms, and large IDF environments where full-height racks are required for high-density server, storage, and switching infrastructure. Its standard 600 mm width and ~1050 mm depth align with common hot-aisle/cold-aisle containment strategies, making it suitable for structured airflow planning and row-based deployments.

From an integration standpoint, the enclosure supports 0U mounting for vertical PDUs and cable managers, enabling efficient power distribution and cable routing without consuming rack space. It includes grounding points for bonding to facility earth ground and supports baying multiple enclosures for scalable rack rows. The unit ships fully assembled with pre-installed casters and leveling feet for positioning within data center floors.

A practical deployment example includes installing multiple SR45UB cabinets in a row within a data center aisle to host blade servers, rack UPS systems, and top-of-rack switches. The adjustable rails allow mixed-depth equipment, while perforated doors maintain airflow efficiency across high-density loads.

This enclosure should not be used in shallow-depth deployments such as AV racks or wall-mounted network cabinets. It is also not suitable for environments with strict space constraints where mid-depth or wall-mount racks are required.
