TrippLite SmartRack 42-Units Premium Enclosure

Optimized for Datacenter Applications

The SR42UB is optimized for datacenter and other high-density IT applications. Its massive front-to rear-ventilation capacity (door perforation pattern providing 65+% open space) meets or exceeds server manufacturer requirements. The SR42UB offers full compatibility with a wide range of airflow optimization accessories as well as cable management accessories. It features integrated baying tabs that make it easy to combine multiple enclosures in rows for datacenter applications. The SR42UB offers guaranteed compatibility with all EIA-310-E compliant 19-in. equipment, and is also 100% compatible with today's state-of-the-art hot-aisle/cold-aisle datacenter configurations.  

Simple Equipment Installation

The SR42UB is compatible with all standard 19-inch rack equipment. It features front and rear pairs of vertical rails with square mounting holes. The rails are adjustable in quarter-inch increments to accommodate equipment depths from 4 to 42 inches. Adjustment is quick and convenient—simply unscrew the rails, slide them to the desired depth and restore the screws. An easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. The rails feature square mounting holes and are capable of supporting up to 3000 lbs. of equipment with included installation hardware. Each rack space within the enclosure is numbered for ready reference.

Toolless Vertical Mounting Rails

The SR42UB features two adjustable vertical mounting rails that support toolless button-mount 0U installation of compatible PDUs and cable managers. Each rail can accommodate two vertical PDUs or cable managers side by side, for a total of four units per enclosure. These vertical mounting rails make it easier to route power and cabling to installed rack equipment. They also reduce cord and cable clutter that could block airflow through the enclosure.

Secure Equipment Access

The SR42UB is designed to provide a safe, secure installation solution for mission-critical rackmount equipment. It features locking, reversible, removable front and rear doors, perforated to promote efficient airflow, and locking, removable side panels. Locking doors and side panels prevent unauthorized access to installed equipment while making it easy for IT personnel to perform inspections, maintenance and equipment replacement. The side panels are half size (two per side) for ease of removal and reinstallation. The split rear door design reduces clearance requirements for service access, allowing the enclosure to be placed closer to a wall.

Vented Top Panel with Cable Ports

The top panel of the SR42UB is furnished with vents designed to help remove warm air from the enclosure and draw in cool air by convection. It also supports installation of standard user-supplied case fans. The top panel is provided with ports for cable routing, and is designed for quick, toolless removal with no need to disconnect cables. The SR42UB is designed with an open bottom to facilitate cable access.    


Integral Grounding System

All components of the SR42UB are grounded to the enclosure frame. Front and rear threaded grounding points are provided for connection to the facility earth ground. The removable front and rear doors feature quick-release ground wires.

Preinstalled Casters and Leveling Feet

To simplify deployment, the SR42UB comes with preinstalled casters and leveling feet. The casters enable the SR42UB to be easily maneuvered into the desired location, where it can then be secured in place by adjusting the levelers. The SR42UB has a rolling load capacity of 2250 lbs., enabling rack equipment to be installed in the enclosure prior to final deployment. Note: the casters are intended for minor position adjustments within the final installation area only and are not designed for moving the enclosure over long distances.


5-Year Product Warranty

The SR42UB comes with a 5-year product warranty and a rapid-response repair/replacement policy that's unmatched in the industry.
