I have a Phoenix Multiplus 24/300/70. When I plug the plug the UTP cable from the Multiplus into the adapter, the Multiplus shuts down. Is this correct operation? I have not connected to my computer as I don't want to damage anything.
When I unplug it, it powers up again as normal.
I am not sure how old the unit is, as I bought it second hand.
Thanks for any help!
