61.1 Resetting the ISG50
If you cannot access the ISG50 by any method, try restarting it by turning the power off and then
on again. If you still cannot access the ISG50 by any method or you forget the administrator
password(s), you can reset the ISG50 to its factory-default settings. Any configuration files or shell
scripts that you saved on the ISG50 should still be available afterwards.
Use the following procedure to reset the ISG50 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.
If you want to reboot the device without changing the current configuration, see
page
753.
Make sure the SYS LED is on and not blinking.
1
Press the RESET button and hold it until the SYS LED begins to blink. (This usually takes about five
2
seconds.)
Release the RESET button, and wait for the ISG50 to restart.
3
You should be able to access the ISG50 using the default settings.
