    • Power distribution unit
    • Coolant distribution unit
    • Control console
  • Large storage facilities
  • Telecommunications equipment
  • Cabinets

Install seismic bracing or anchors for computer equipment with the following characteristics:

Height

    Height is greater than 2-1/2 times the base width.

Spacing

    Closely spaced or less than 18″ apart on ground floor.

Consult a structural engineer for design of bracing or anchors.
