do you have another workstation (PC) that is on the 10.1.3 subnet? Have you tried connecting to the array from that PC using the array IP address?  glen
I have 2 AX150 arrays that have the same problem. I connected through the serial port using dialup networking and set the manageport IP to say 10.1.3.70. Now the only way  I can access the array using the new IP is if the serial port and dialup network connections are up.  I rechecked the network ports on the array and they are up with the correct IP.  If I make a connection using the IP while I have the serial port connected and then remove the serial cable I lose the network connection.   I did a ping from the array to another device on the 10.1.3 network and I can see the activity on the management not the serial port.  Has anyone seen this issue?
AX150 can't access array unless serial port has direct connection
