I have a MAX HD2 HW5, firmware version 7.02, the power input is 10v-30v, the background of the network port shows that POE can be turned on, can I connect a 48v power supply to use POE, and I found the corresponding firmware upgrade in the support center Package, manual upgrade prompts an upgrade package error, using online upgrade, there has been no progress display, I don’t know how to operate to upgrade.
thanks
