Thanks for your question.

Is the data accessible? If you are down you should call phone support. Is there are rouge DHCP server on your network taking over the IP address assignment? Are you able to switch it to static? Are there any errors on the switch that the management port connects to?


Let us know if you have any additional questions.

Glad you got it resolved. That is strange that it changed on its own.
