#PoE
We utilize various POE switches, including 8-port, 24-port, and 48-port models, all sourced from TP-Link. We implement a PD device with a power rating of up to 10W, employing the LM5071 as our POE PD IC. Preceding this IC, we use RJ45 and a signal transformer (749013011A) separately. Unfortunately, we've encountered issues with multiple POE PD IC failures and burnt signal transformer ICs. Our suspicion falls on the POE switch, potentially due to spikes or overcurrent, especially considering that out of 240 devices, 20 are experiencing this issue and their ICs have been damaged. give some technical support.
