Upgrading firmware on SonicWall SWS14-48FPOE
I connected a SonicWall SWS14-48FPOE (allowing auto discovery, basically following the directions in the quick setup that came with the switch) to X2 on a new SonicWall TZ370 (SonicOS 7.0.1-5030-R4007) and from what I was reading, I should have been able to on the TZ370 go to Device -> External Controllers -> Switch Network -> Overview and select upgrade firmware (switch is currently at 220.127.116.11-16 and going to 18.104.22.168-13s). I get an Error dialog with "Switch firmware upgrade has failed".
What I suspect is that the switch can not get to the internet to download the firmware. Looking at the rules before and after adding the switch, it looks like some rules were added to allow the switch to access the internet. But I'm new to SonicWall and I'm not positive I'm correct on this.
X0 is our internal LAN 22.214.171.124/255.255.254.0
X1 is the WAN
X2 is the the switch 192.168.168.0/255.255.254.0
Any help - particularly pointing to the correct documentation would be appreciated.
