Hedgehog 4 generation 2 console software upgrade question

Hi All,

We have a Hedgehog 4 generation 2 that was originally purchased as being a standard 4. Not a 4N or 4X. However, the hognet tab is available in settings, and can be configured and acts as expected when you pug in an ethernet cable. That is, the status switched from "down" to "up", and the count changes on the TX and RX fields as if it has data in and out. I was going to do the software upgrade making it a a 4X, but now I'm wondering if it was already done. Can anyone tell me an absolutely sure way to tell if it's had the software upgrade done or not? Is there somewhere I can look in settings / control panel, etc that will show if it has been upgraded?

Thanks! I really appreciate any help you can give me!
