These racks play a role in a puzzle in the room. Samus is required to use them in order to progress, by moving the racks into a staircase shape so she can access the door to Ventilation Area B, which will ultimately lead to her fighting Dark Samus for the first time. A ledge opposite the room contains an Energy Tank; this can be obtained by resetting the racks in ascension from Alpha to Gamma. On a later visit to the room, the racks may be set into another configuration. Samus can scan another console to reset them to the last recorded position.
