Ok, don't laugh. I know I shouldve read before doing.
SNAP 4500
GuardianOS 2.6
4 x 250GB
Try to upgrade it to 4.4.049.
It took the file and ask to reboot to finish upgrading process.
After reboot, all lights are GREEN and drives look like its booting, but I can't see it from the network. Tried the reset button to factory and still can't see it.
What else can I try. PLease....
