How do you tell if you have a SB8200 v2 Or V3?
This does not work
You can determine if your Arris SB8200 is a V2 or V3 model by checking the tenth digit of the serial number located on the bottom label of the modem, or by looking at the backplate color and ethernet port color.
Visual Method:
V3: The backplate will be grey with orange ethernet ports.
V2: The backplate will have green, blue, blue, and then red-ish color with silver ethernet ports.
Mine does not show any of this. The tenth digit is a 6 not 2 or 3

Serial Number {edit : personal information}
So I guess mine is 1 generation
