I've lost connection to my cloud due to a network problem and I can't get in the drive

Hi, I had a unit as a back up in my network. The switch I was using blocked the VLAN that managed the IP of the drive, so I can’t access the data and the recovery email is lost. I’ve dismantled the drive in order to gain access but didn’t work neither.
What do you recommend?
Thanks!!!
