<p>We have a 3706 (old but working normal) with Firmware 1.01h. Got the upgrade downloads for 1.32A, 1.40k and 1.41c. I followed the upgrade instructions and prepared a thumb drive with the two upgrade files (nb0 and cab). After power-on the instrument starts using the thumb drive (LED blinks) but doesn't enter into the upgrade sequence. In the upgrade instructions they say one should do nothing but wait some minutes (and then some LAN initialization). The instrument just boots normal and "Slot" still displays 1.01h.</p>
<p>What's the trick for firmware upgrade? Need to unpack the cab file? Need to use the upgrade command? Some jumper?</p>
