Network port resetting back to factory default

Using a Relay Controller 4-Channel General Purpose SPDT + 8 Channel ADC ProXR Lite 10 amp. I am turning on a 110 buzzer that I have used in the past with older relay controllers. This controllers network setting resets to default when I turn on the relay with power going through it. I set the ip to manual and after I turn on the relay the network lights on the card go off and then back on and it is reset back to dhcp. If I remove power through the relay, it is fine. The board stays powered and the buzzer keeps sounding.

does the module reset to factory settings if the buzzer is not connected to relay board ?
