We've recently inherited a DS3400. I began the process of upgrading the firmware is it was on 06.70.22.00. I successfully upgraded to 06.70.69.00
I then tried to upgrade to a version 7 firmware, ( can't remember exact version of the top of my head). It started off ok and was looking good until it said that it had lost connection to the controller. Now I can't access the unit on either controller although it does ping.
Tried restarting and removing a controller but no luck. Any ideas would be greatly appreciated
