FortiAnalyzer 400E Help

Found a FortiAnalyser in our store room, trying to set up.  Instructions says to plug laptop into a port on back and give self a 192.168.1.* address and connected to the analyser on 192.168.1.99.

I've tried this on all 5 RJ45 sockets on the back of the box.  No connection.

I've ran wireshark while plugged in to each port to see if arping out, no look.

I've plugged a keyboard and monitor in, get the post on the screen then that's it, keyboard doesn't work.

Not under support, think it was a freebie chucked in at some point .

Any help much appreciated.
