The FireBrick has a simple factory reset process to erase the configuration allowing you to reconnect using the default IP addresses described in Chapter 2. This process can be very useful if you ever make an error in the configuration that stops you having access to the FireBrick for any reason, or any other situation where it is appropriate to start from scratch.
This process will start the FireBrick in a factory reset mode temporarily - the configuration stored in flash memory has not yet been altered or deleted at this stage.
If you do not save a new configuration at this stage, then the FB6000 will revert to the existing saved configuration when next powered up or restarted.
It is also possible to recover the configuration stored in flash memory, if you know an administrative username and password for it - this gives you an opportunity to correct a configuration, such as where you had made a change that prevented you from accessing the FB6000.
To factory reset permanently follow the same process but with ports 1 and 2 looped - this will overwrite the configuration stored in flash memory, so use this reset method with caution.
