  • Page 103: Rebooting The System

    Rebooting the System There are two different ways of rebooting egnite Querx – via the web interface (soft boot) or by interrupting the power supply (cold boot). Please note that Querx logs every reboot along with the data its sensors measures.

    Reboot when Establishing an Ethernet Connection egnite Querx can function as a data logger when it is not connected to a network. The tracked data can be retrieved at a later date, when the connection is re- established. If an Ethernet cable is plugged into a running device, it will reboot. A reboot will also be triggered if the connection is interrupted and re-established at a different point.

    Performing a Hardware Reset Should you not be able to access the configuration area, for instance because you do not have the access data at hand, Querx can be returned to the factory settings via a hardware reset. You will require a biro. Some biros' tips are not thin enough to press the button.
