Features

Standard-Depth 55U Server Cabinet Accommodates 19 in. Rack Equipment
This SmartRack® 55U rack enclosure is designed for network wiring closets, retail locations, classrooms, back offices and other areas with essential rack-mount IT equipment. Constructed from heavy-duty steel with a durable black powder-coated finish, the SR55UB has a maximum stationary load capacity of 3000 pounds (1363 kilograms) and a maximum rolling load capacity of 2250 pounds (1022 kilograms). 

Exceptional 55U Height Lets You Make the Best Use of Valuable Floor Space
The extra height allows you to stack more equipment vertically and make optimal use of available floor space. This 55U rack cabinet has a footprint of 24 inches (600 millimeters) wide and 43 inches (1092 millimeters) deep. 

Keeps Important Equipment Secure
The reversible front door, split rear doors and half-size side panels lock securely to help prevent damage, tampering or theft. The doors, side panels and top panel are designed for quick release, making it easy to access connected equipment and cabling with little effort. Convenient top access ports and an open bottom allow easy cable routing through the cabinet. The vented doors allow generous airflow (more than 65% open space) from front to rear to keep your equipment cool and functioning at their peak.

Easy Enclosure and Equipment Installation
This 55U server rack comes fully assembled for quick and easy deployment with pre-installed (and removable) casters that let you maneuver it over a level, smooth, stable surface and through a standard seven-foot (2.1-meter) doorway into position, where it can be stabilized by adjusting the levelers (also removable). Front and rear mounting rails accept standard rack equipment up to 37 inches (940 millimeters) deep. Toolless 0U mounting rails allow quick installation of up to four compatible PDUs and vertical cable managers.

Designed for Baying Multiple Enclosures in a Row
Built-in baying tabs allow the combination of two or more rack cabinets in a row. Center-to-center width can be set at 24 inches (600 millimeters) to match standard data center floor tiles.

Meets Payment Card Industry Standards
The SR55UB provides physical equipment and media security required for PCI DSS (Payment Card Industry Data Security Standard) compliance. This is essential for companies that process, store and/or transmit credit card information.

Typical Applications

Store and organize rack-mount equipment in a network closet, data center or other area where you need components to be secure
