Vendor-neutral square hole/cage nut mounting for guaranteed compatibility with all EIA-310-E compliant 19" equipment. Enclosures ship fully assembled for rapid deployment. Toolless mounting slots allow quick installation of PDUs and vertical cable managers. Adjustable mounting rails include and easy-view depth index to eliminate time-consuming measurements. Lightweight modular doors and side panels provide safe, convenient service access. Integrated baying tabs facilitate combining enclosures in rows from standard data center baying applications. SmartRack enclosures support cooling, cable management, power distribution and monitoring features that keep critical servers and network equipment operating nonstop. Perforated doors permit massie front to rear airflow that exceeds servers manufacturer requirements. Enclosures are fully compatible with hot-aisle / cold-aisle data center configurations.

Key Features

  • Ships fully assembled for rapid deployment
  • 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 fo compatible PDUs and vertical cable managers. Moutning slots are arranged in an industry-standard pattern compatible with a wide variety of accessories. Each rail can accomodate 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/94 cm (front to rear rail).
  • Front door is locking, reversible and removable.

  • Convenient grounding system. All components are grounded to the enclosure frame which includes multiple connections for facility ground. Front and rear doors include quick-release ground wires.
  • Open bottom for cable access.
  • Top panel has generous cable access holes. Panel can be removed toollessly in seconds without having to disconnect cables first.
  • Designed and tested to meet Telcordia GR-63-CORE Network Equipment & Building Systems (NEBS) requirements for Zone 4 Seismic Earthquake Environments.
  • Meets all enclosure requirements towards PCI DSS (Payment Card Industry Data Security Standard) Compliance
  • Compatibility with airflow optimization accessories as well as cable management accessories.
