11 Back-up and redundancies

  11.1 The system configuration should allow one of the two possibilities for the layout of the back-up and redundancy functionality for the CAM, CAM-HMI:

  • .1 in case of a failure of the CAM-HMI, it should be ensured that the connected systems present their alerts individually (a system failure of the CAM-HMI functionality should not lead to the loss of the alert announcement functionality); and

  • .2 or, if functionality from systems and equipment is transferred to the CAM and CAM-HMI, a back-up should be provided. The back-up arrangement should enable a safe takeover of CAM functionality and ensure that a CAM failure does not result in a critical situation. The power supply of the back-up arrangement solution should be resistant against single failures.

  11.2 In case of a breakdown of one task station, at least one other task station should be able to take over the CAM-HMI task.
