Reset button
Pressing the reset button restarts the device and loads the saved configuration (startup-
config or stick-config). As a protection against accidental triggering, the reset button is in a
concealed place and can be reached with a pointed tool (e.g. paper clip).
If the reset button is pressed for more than 5 s, the modem enters firmware update mode.
ADVICE
If the running configuration (= running-config) does not match the saved configuration (=
startup-config) it is lost with the restart.
