Using these devices to extend POE security cameras. Less than 3 months in use and one of the media converters has lost power. Getting a replacement - rediculas. After 3 days of email exchanges, they want me to return the pwr media converters and accessories for a replacement. I have already explained three times that I only need 1 power supply. Abandoned, found a D-Link switch with specs and used with modification. Much luck
