A wrong power adapter connected to USRP and now it doesn't work (LED doesn't blink)

My adviser accidentally plugged in a laptop’s power adapter into a USRP
for
a few seconds and now it doesn’t respond and GNU Radio doesn’t detect it
either after connecting to the laptop and testing it. What do I do? I
hope
that there must be a fuse that is replaceable or some sort of mechanism
to
prevent the USRP from being fried. Any help will be greatly appreciated.

Thanks,
John

Do the LED’s work? If not, check the fuse on F501.

For a USRP1, F501 will provide some protection. Not guaranteed or
anything, but some. Check F501 for continuity.

For a USRP2, F101

For an N2XX, F101
