USRP fan connection on Rev3 boards

GNU Radio

Hi,

Finally taken delivery of my USRP enclosure for my Rev3 USRP. (Matt,
please
consider using other shipping than UPS - I paid 600$ in shipping and
customs
and it took weeks to process).

Problem is the rev 3 has a 4 pin jumper J1001 instead of the rev4 2 pin
jumper. How do I connect it? (Eric C. asked this ages ago but I
can’t
find the answer).

Regards

Steve

$600? US Dollars?

Shipping by UPS does cost more than postal service, but it is much
faster and has the advantage of actually getting there at 99.9+% rates.
Our experience with postal service was that items would be lost between
2 and 3% of the time depending on the country.

As for customs fees, those should be the same no matter what shipping
method, right?

J1001 is all grounds, no power. Rev 3 was designed without a fan, so
you’ll need to solder directly to the pins of the power connector.
