Wrong Power Supply for MP40?

[rooneyj889]

Hey, I recently bought a used MP40WQD and it just came in today. I got it all hooked up but it was blinking green, indicating it was in battery backup mode. I do not own a battery backup, so I did some research and I think it came with the wrong power supply but I am not positive. I have attatched a picture, but it seems like a power supply for the battery backup.

I'm not sure. I don't have the battery back up and only have mp10's. Can you contact the seller and see if they inadvertently sent the wrong power supply?
