Yes correct.

Thus my surprise that the front panel firmware illumination shows (to my knowledge, may be wrong) that the firmware is v8.

I didn't realise this was possible (a) with a v1/v2 chassis (which the listing clearly is, round buttons), And (b) no cards that are v8 cards!

I am wondering how the user has 'tricked' the config programme/the unit itself into successfully receiving 861v8 firmware.
