I have a new F4-421 and am having problems getting through initialisation.
To start with, I couldn't get the NAS to get an IP address. Its plugged directly into the router.
The power light was on solid green, the network light was flickering green and the 4 HDD lights were solid RED.
No sign of the device on the router, so probably an issue with the network.
Finally fixed by plugging into a different port on the NAS - I know you say you can only use one network port, but you don't say which one
Now it gets an IP address and appears on the network.
I installed the two WD RED 4TB drives and now I have 2 green HDD lights.
(Drives are WDC WD40EFAX-68JH4N0)
TNAS-PC can see the NAS and when I click on login I get the initialisation page in my browser.
Auto download failed immediately, so I manually downloaded 4.1.30 from the TM website and tried manually.
File unzipped OK and initialisation started at 50%, then promptly failed at 55% with the message "Installing has TOS failed! Please restart TNAS and try again".
Have retried multiple times, all with the same result.
Help please.
