8.1 Resetting the NSG
If you cannot access the NSG by any method, try restarting it by turning the power off and then on
again. If you still cannot access the NSG by any method or you forget the administrator password(s), you
can reset the NSG to its factory-default settings. Any configuration files or shell scripts that you saved on
the NSG should still be available afterwards.
Use the following procedure to reset the NSG to its factory-default settings. This overwrites the settings in
the startup-config.conf file with the settings in the system-default.conf file.
Note: This procedure removes the current configuration.
1
Make sure the
SYS
LED is on and not blinking.
2
Press the
RESET
button and hold it until the
SYS
LED begins to blink. (This usually takes about five seconds.)
3
Release the
RESET
button, and wait for the NSG to restart.
You should be able to access the NSG using the default settings.
