Appendix A. Factory Reset Procedure

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.

Disconnect all network and power leads :-
Connect lead between far left and far right ports (ports 1 and 4) :-
Connect power and wait a few seconds for all port LEDs to be on steadily. Power LED blinks :-
Disconnect loop, leave power connected. LEDs cycle and power LED blinks :-
Note
There is a timeout of 20 seconds in this process - if the loop is present for longer than 20 seconds, the power LED will stop flashing and the factory reset will be aborted

Connect network to left hand port. Power LED comes on solidly.

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 disconnect the power then the config will revert to the previous state and no longer be reset, so it is important to connect your laptop, etc, to the FB2500 after removing the looped cable and not power cycle in-between.

If you do not save a new configuration at this stage, then the FB2500 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 FB2500.

A.1. Other types of reset

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.

To temporarily revert the configuration to the last-but-one saved config, follow the same process with ports 1 and 3. Again, if the FB2500 if reset before saving a new config, it will revert to the last saved config again.
