I just purchased 2 Dell UPS 1920R rack mount power supplies that were new(but old inventory) that still have some warranty on them.

One of the service tags correctly pulls up the Dell 1920R, the other does not, it pulls up a Dell DR6000 which is definitely not what I have.

I've seen posts before about service tags pulling up slightly different models in the same product family but this is completely different. 

What do I do?

Thanks.
