Hello Daniel,
many thanks for your suggestions!
Just one last question: on the Drivers & Downloads page for my product, it makes mw download this file:
http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/poweredge-2950?driverId=XKXCF&osCode=XI51&fileId=3104071896
(that's cdu_2.2_core_702) instead of the one you suggested.
Which is the correct one?
Thanks again
Matteo
