Pfsense not booting after not proper shutdown

[GianRocc]

I have installed PFSense 2.3 on our WatchGuard XTM 510 and it works fine about a week, after shutting down the pfsense using the physical switch at the back it wont boot anymore. serial connection only shows "CCCCC" continuosly. how can i restore the previous configuration?

Use your backup (you make periodic backups, right?) with a new install to get back to working order. Alternatively, read the config off the storage medium using a computer, and recover the config.xml from that, and then reinstall using that config.
