Overview

The SR25UBEXP is an expansion model used when several cabinets are bayed together. It has doors and a roof but no side panels. Its integrated baying tabs make it easy to combine multiple enclosures in rows fro data center application. The SR25UBEXP is also compatible with hot aisle/cold aisle configurations.

The SR25UBEXP houses 3000lbs of standard 19-inch rack equipment in 25U. Offers vendor-neutral square hole/cage nut mounting for guaranteed compatibility with all EIA-310-E compliant 19" equipment. Its front and rear pairs of vertical rails are adjustable in quarter-inch increments from 4 to 37 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 these 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.

The top panel of the SR25UBEXP is vented to help remove warm air from the enclosure and draw in cool air by convection. The top panel includes ports for cable routing, and can be quickly removed without tools. To facilitate cable access, the SR25UBEXP is open-bottom.

All components of the SR25UBEXP 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.

To simplify deployment, the SR25UBEXP 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.

Features

  • Ships fully assembled for rapid deployment and roll into place on heavy-duty pre-installed casters (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.
  • Toolless 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.
  • Massive front to rear ventilation capacity. 65+% open space in door perforation pattern meets or exceeds server manufacturer requirements.
  • Maximum usable internal depth of 37 inches (front to rear rail).
  • Weight ratings of 3000 lb stationary and 2250 lb rolling.
  • Front door is locking, reversible and removable.
  • Rear doors are locking and reversible. Split rear door design reduces clearance requirements for service entry allowing the enclosure to be placed closer to a wall.
  • Built in baying tabs allow enclosures to be combined securely in rows. Center-to-center width can be set at 600mm or 24" to match standard data center floor tiles.
  • Leveling feet extend to allow enclosure to be positioned on uneven floors. Levelers are removable.
  • Compact design allows the enclosure to roll through standard height commercial doorways.

Frequently Asked Questions

A rack unit (commonly referred to as a "U") is a standard measure of the height of a device in a server rack. One rack unit is 44.45 mm (1.75 in) high. The height of a one rack unit device is described as 1U, a two rack unit device as 2U and so on.
The IEC (International Electrotechnical Commission) uses a two digit code to define specific protection capabilities. For a full explanation of IEC rack enclosure ratings, click here
