Overview

The SR42UBMDEXPND is part of our new line of mid-depth rack enclosures. Our new line offers 36" (927mm) depth opposed to the standard 42" (1050mm).

The SR42UBMDEXPND is a 42U SmartRack enclosure with NO doors and NO side panels. The 'EXP' version is an expansion model used when several cabinets are bayed together. Its integrated baying tabs make it easy to combine multiple enclosures in rows for data center applications. This enclosure is also compatible with hot-aisle/cold-aisle configurations.

The SR42UBMDEXPND houses 3000 lb of standard 19-inch rack equipment in 42U. Its front and rear pairs of vertical rails have square mounting holes that are adjustable in quarter-inch increments from 4 to 31 inches. Adjustment is quick and an easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. Each rack space within the enclosure is numbered for ready reference.

Two of the adjustable vertical mounting rails support toolless button-mount 0U installation of up to four compatible PDUs and cable managers. This feature makes it easier to route cabling to rack equipment and reduces cord clutter.

All components of the SR42UBMDEXPND are grounded to the enclosure frame. Front and rear threaded grounding points are provided for connection to the facility earth ground.

To simplify deployment, the SR42UBMDEXPND comes with preinstalled casters that enable it to be easily maneuvered into the desired location, where it can be secured by adjusting the preinstalled levelers. Note: the casters are intended for minor position adjustments and are not designed for moving the enclosure over long distances.

The SR42UBMDEXPND comes with a 5-year product warranty. As part of the SmartRack family, the SR42UBMDEXPND is compatible with Tripp Lite’s extensive range of rackmount accessories, enabling you to customize your solution to meet any requirement.

Features

  • Ships fully assembled for rapid deployment and roll into place on pre-installed casters, allowing the enclosures to be pre-configured and rolled to the final installation location. Casters are removable.
  • Front and rear sets of equipment mounting rails adjust in 1/4" increments. Adjustment is quick and convenient. The easy-view depth index ensures consistent rail placement without requiring time-consuming measurements.
  • Tool-less accessory mounting rails (2 rails per enclosure) include slots for quick installation of compatible PDUs and vertical cable managers. Mounting slots are arranged in an industry-standard pattern compatible with a wide variety of accessories. Each rail can accommodate two vertical PDUs or cable managers side-by-side (four items per enclosure).
  • Enclosure includes mounting hardware of 50 pieces of M6 cage nuts and 50 pieces of M6 screws
  • Textured powder coat finish for tough resistance to environmental concerns such as deployment in warehouses.
  • Maximum usable internal depth of 31 inches
  • Weight ratings of 3000 lb stationary and 2250 lb rolling.

  • Leveling feet extend to allow premium open frame racks to be positioned on uneven floors. Levelers are removable.
  • Compact design allows the premium open frame racks to roll through standard height commercial doorways.
