Recovery - NetModule NB1600 User Manual

Please note that the admin password will be also applied for the root user which can be
used to access the device via the serial console, telnet, SSH or to enter the bootloader.
You may also configure additional users which will only be granted to access the summary
page or retrieve status information but not to set any configuration parameters.
A set of services (USB Autorun, CLI-PHP) are by default activated in factory state and
will be disabled as soon as the admin password has been set. They can be enabled again
afterwards in the relevant sections.

5.1.2. Recovery

Following actions might be taken in case the router has been misconfigured and cannot
be reached anymore:
1. Factory Reset: You can initiate a reset back to factory settings via the Web Man-
ager, by running the command factory-reset or by pressing the reset button.
The latter would require a slim needle or paper clip which must be inserted into
the hole below the USB port. The button must be hold pressed for up to 5 seconds
until all LEDs flash up.
2. Serial Console Login: It is also possible to log into the system via the serial port.
This would require a terminal emulator (such as PuTTY or HyperTerminal) and an
RS232 connection (115200 8N1) attached to the serial port of your local computer.
3. Recovery Image: In severe cases we can provide a recovery image on demand which
can be loaded into RAM via TFTP and executed. It offers a minimal system image
for running a software update or doing other modifications. You will be provided
with two files, recovery-image and recovery-dtb, which must be placed in the root
directory of a TFTP server (connected via LAN1 and address 192.168.1.254). The
recovery image can be launched from the boot-loader over a serial connection, you
will have to stop the boot process by pressing s and enter the bootloader. You
can then issue run recovery to load the image and start the system which can
be accessed via HTTP/SSH/Telnet and its IP address 192.168.1.1 afterwards.
