New install on a pfsense appliance

[markusxyz]

I've a rack mountable pfsense like this:

If I would reinstall pfsense how can I do?
If I'm right I have to put the .img in a usb pen and connect  to Pfsense. Then I connect a serial cable to Pfsense and if a reboot the Pfsense it should start the installation. Is it correct?

Does it have serial console on the back? If not, you might need to open the box…
If it does, you might be able to take control & boot from usb? (seen on the picture at least it has that on the front)

Ok, I've checked it has serial console.

Yep so use the memstick-serial image and write it to a USB flash drive. Boot from that and use the serial console to reinstall to the SSD.
