In Routine Jeremie had to take the boards out and swap them around as XANA had mixed them up to sabotage the Materialization program. In Sabotage, XANA possessed the Kadic gardener and used him to enter the Supercomputer room, remove the boards and damage them with electricity. The damage caused on the boards caused major glitches, bugs and power failures on Lyoko, Jeremie even quotes that some of the supercomputers functions were damaged as he couldn't launch a return in time.
