{"wiki":"en","slug":"guide-system-changeslot","markdown":"# Switching the Slot of the Behnke Station\n\nThis setup guide describes how to switch the active firmware slot of the Behnke Station.\n\nThe Behnke Station uses a so-called two-slot system. This means two firmware versions are installed on the device at all times. This method increases operational reliability, because if a firmware update fails, the station can fall back on the previously installed firmware version and remain operational.\n\n%[NOTE_REQUIRES_BASIC_SETUP](NOTE_REQUIRES_BASIC_SETUP)%\n\n<!-- block: slot-ueber-die-weboberflaeche-wechseln -->\n## 1.
