Hi,
Our company bought 3 cAP Access Points, and two of them stoped working after being configured (only disconected from the electricity, and reconected after one day). AP still broadcast SSID but ethernet socket get up for 3 - 4 seconds and goes gown. I did factory reset but it didn't help. The third AP didn't work from the beginning, and was send under warranty to service. They told that it was overvoltage. How cen it be, when i only plugged it to PoE switch, wich powers other devices (one of them is Mikrotik router) and nothing happens to them. It is possible that other two are also overvoltage. What else can i do to with these two AP?
