Dead Radio?

I have three SM boards. All doing the same thing.

The appear to power up fine - lights flash, they do their normal thing.

I get link to the ethernet interface on my laptop.

Problem is, I can’t ping them. Tried using the reset plug and still the same issue.

Is there any thing else I can try or are they hosed.

These were all working radios. I typically purchase all my Moto equipment used. Is there a way to check and see if they are still under warranty?

Find the original sales order and call moto?
