Thought I would post a lesson learned about the 1794-AENT.
The System Integrator we had working for us had comissioned a number of 1794-AENT units calls that the latest batch won't configure.
After working back and forth with RA Techconnect it finally turns out that we had been using 1794-AENT firmware 4.1 from our store room and then got into a fresh shipment of 1794-AENT Firmware 4.3's. The BOOTP/DHCP Tool revision 3.03 we were using needed to be upgraded to 3.05 to configure the 1794-AENT.
