Hi all. I had a question on the undervoltage protection on the Cisco IR1101 router. I am supplying the IR1101 from a solar MPPT controller/12V battery system and have run into an issue which has resulted in the IR1101 seeing a fluctuating voltage on its input terminals (ultimately the battery BMS shutdown and the MPPT remained connected directly to the IR1101 with no battery voltage reference). The voltage that was supplied to the IR1101 from the MPPT can not physically get anywhere near the 60VDC however may have been sitting below the 9.6VDC lower limit. In short the lights on the IR1101 were flashing whilst the unstable voltage was present and then when the system was reset and a stable 12V power supply was reinstated the unit would no longer come on at all. Clearly we have damaged the unit in some way but I am trying to understand how? Any help appreciated
