Install Rails in Square or Round Hole Racks

  1. Locate the appropriate rack unit (RU) height.
    The DE2-24P Drive Enclosure requires two standard mounting units (2U) of vertical space in the rack.
  2. Remove the rails from the Drive Enclosure packaging.
  3. Position the front rail-location pegs fully inside the holes in the front rack posts where you plan to add a Drive Enclosure.

    Make sure the rail label faces the inside of the rack. Align the rail flange inside of the rack flange. Position the rail-location pegs fully within the rack holes.
