Hi Craig Every ePMP radio manufactured goes through a functional test where radios are configured as a SM and registered to a golden AP inside a RF chamber. After a good signal RF link is established a quick iPERF test is run to verify traffic via Ethernet and RF. This ensures validation of RF connections & Ethernet. This functional test is the last step after the units are assembled but the units also go through board level validation in earlier stages of manufacturing.
The factory test procedure went through some updates as new SW releases were made available throughout 2014. Some earlier units built (early 2014) did not verify our micro controller functionality and some errors were observed during SW updates from early 1.4.X releases to 2.0 All in all, we are very closely monitoring any and all quality issues reported by the field and will gladly provide an advanced RMA from engineering to get our hands on any unique HW defects. As of now, our factory functional procedure is designed to catch any blatant HW defects but may not catch the occasional cold solder defect which may be uncovered over time. Unfortunately, putting every ePMP radio through a burn in cycle in the factory would not be economically viable. Ray
