Rack elevation planner

Lay out a rack before you buy it. See whether everything fits, whether the power feed copes, and where the heavy items sit.

  • Check:Fill unused spaces with blanking panels, so hot air cannot loop back to the intakes.

Power and weight are typical values per class of device. Use the data sheets of the real equipment, and keep the heaviest items low.

Method

How the numbers are worked out

Elevation

Equipment is stacked from the top (U1) in the order listed. A rack unit (U) is 44.45 mm of height.

Checks

Space used against rack size, power against the feed, weight against the rack's rating, a warning for heavy equipment high up, and for open spaces without blanking panels.

Assumptions and limits

  • Power and weight are typical figures per class of device; the equipment data sheets replace them.
  • Cooling, cable management and door clearance are separate design points.
