last time I had to run HQIP there was a note how to connect the cables.
Did you start the HQIP image and did you read everything carefully?
You're quite right, the HQIP does show the 'diagram' how to connect the cables if you want. The problem is, in the KB article (http://wiki.diagnose.fortinet.com/index.php/Running_an_HQIP_(Hardware_Quick_Inspection_Package)_test) it says this, to the letter:
Hopefully, you'll agree that it is quite confusing, especially if you've never run the HQIP before. And most people, luckily, didn't. It asks you to wire the interfaces before actually installing and running the HQIP firmware.
But, you are right, once the test is run, it does instruct you how to do the wiring.
All oppinions/statements written here are my own.
