[Discuss-gnuradio] Help polarity inversion

[Marco Bottino]

Hello,

I was doing some test with a 6Volts battery with the USRP in order to be
able to use my USRP outdoors.
(Sonnenschein A506/4.2 s http://www.sonnenschein.org/A500.htm)
Everything was fine when I unintentionally inverted the polarity of the
battery.
At the moment, connecting the power converter to the usrp, the led
doesn't blink anymore and the fan doesn't work too.
I'm really not familiar with the electronic so I don't know what can be
happened inverting the plus with the minus...
Is there any hope to bring back to life my USRP? Can the fuse have saved
the board?
Any help will be very happreciated.

Thank you,

Marco
