Firmware Update Cisco SG350

Posted by robd on January 12, 2022

I had to update a Cisco SG350 recently, which should have been really easy but ended up being a bit of a pain.

Here’s how I’d do it again:

  • Download the firmware:

  • Ignore the GUI, pretend it never existed, as best I can work out it just doesn’t work well.
  • Download a tftp software, I suggest tftpd64 as it brilliant:

  • Run the tftp software and point it at the firmware, make a note of the IP.
  • SSH to the switch with putty and run the following to check the version:
show ver
  • Then run this command on the switch (The IP if the IP of the tftp software):
boot system tftp://

  • Now reboot:
  • Once it’s rebooted, check the version, and you are done!
show ver

  • You can also use the Switch Web management page via your browser to update firmware under the File management section. No Need for TFTP.
