Product Features

  • All the great performance of our Performance Plus Cabinets in an extra-wide version.
  • 31.5" width holds wide, side-breathing equpiment.
  • 36" depth gives you extra room for cable management.
  • Weight capacity of 2000 pounds; unlike other cabinets, weight capacity is not affected by rail position.
  • Guaranteed for life!


  • Great for blade servers!
  • Optional Side Vent Baffle Kit redirects hot exhaust from side-breathing equipment out the back of the cabinet.
  • Baffle is designed for hot aisle/cold aisle installations.
  • Mesh front and mesh split rear doors provide maximum ventilation to your hot CPUs.
  • Full ventilation helps to maintain airflow around servers.
  • Unique interior support provides more space between the frame and the cabinet's exterior.
  • Torsion free for strength and rigidity.
  • Doors are supported by the top and bottom frames.
  • Rails feature M6 mounting holes.
  • Door stiffener stabilizes door and provides additional mounting points.
  • Doors panels secure to the outside of the top and bottom frames, providing maximum access to the inside of the cabinet.
  • Seismic rated to Zone 3 according to Telcordia GR-63-CORE (NEBS).
  • Ground studs on all surfaces.

  • Black Box® Performance Plus Server Cabinets feature unique internal rails that double as a frame. This construction provides extraordinary support plus it gives ample space for cabling and ventilation.

    The upright rails' Z-shaped multifold profile offers multiple mounting surfaces for rackmounting equipment and for mounting zero U accessories such as power strips. The rails are fully depth adjustable even in a bayed multicabinet installation. External cabinet surfaces such as doors and side panels fasten to the upper and lower frame and don't affect load-bearing capacity.

    Capacity is something this cabinet has a lot of! It holds an amazing 2000 pounds regardless of where you position the rails. Compare that with some other cabinets that claim to hold 2000 pounds but do so only if the rails are left in their original configuration.

    Doors hinge left or right and feature a door stiffener for extra stability and additional mounting surfaces.

    Performance Plus Server Cabinets feature mesh front doors and mesh split rear doors to provide maximum ventilation for hot CPUs—even blade servers. The doors have 64.5% open area, exceeding server OEM vent requirements. With the addition of the Enclosure Blower, Performance Plus Cabinets provide the maximum ventilation available in a cabinet.
    At 31.5" wide, the Extra-Wide Server Cabinets give you room for wider, side-breathing equipment, such as Cisco® Side-Vent Switches. Add the optional Side Vent Baffle Kit (RM3110) to redirect the hot exhaust out the back of the cabinet. The baffle is designed for use in hot aisle/cold aisle data center installations. A model is also available with sides.
