I just loaded the firmware (kirkwood standalone) on a 5big 2 using 29 July 2019 release fvdw-sl console 6-0 with 18-1 firmware installer and image writer.
I have just one disk installed (I received the unit with no drives as a used machine). The lacie firmware is note as 1.4.4 i think.
But the kirkwood seemed to load fully on telnet ( I could see the LAN ports flashing and drive slot flashing responding per the console and went through all actions including the reboot at the end. Everything looked sucessful in terms of loading the firmware.
The problem is I cant find the IP address and connect to the NAS. The assistant program does not find it either.
Any clues what is wrong? I have tried all manner of things on the network side (I am using a small network switch only not a router).
