Module Firmware Update – Industrial Raspberry Pi (revolutionpi.com)
What can I do if I can no longer log in remotely on the RevPi?
If you can no longer access your device remotely, you can connect directly to the RevPi.
Simply connect a mouse, keyboard and a monitor. Then you can log in and remove or modify the firewall settings.
If you still have trouble logging in, the easiest option may be to reinstall the image. Please see the following link.
