Any QNX-based Edge device has a “system shell,” providing low-level access to a few basic platform settings. Using a special power-up mode and
a serial connection via a USB-to-MicroUSB cable connected to the Edge device’s Debug port, you can access this system shell. Note that system shell is also available via SSH (providing that SSH
is enabled in the Edge device).
Typical usage is for troubleshooting. However, in the case of IP address misconfiguration, you can use the serial system shell
in order to regain access to the unit.
NOTE: Also, depending on your preference, you may wish to use the serial shell to set the Edge device’s IP address.
