Hi Piotr, the boot can be loaded through TFTP. When you go to Admin -> File Management -> Upgrade/backup Firmware, you'll notice the boot option is grey when the HTTP/HTTPS is selected. If you choose the TFTP option everything becomes active.

If you don't have a TFTP server, you can download TFTPD32 (332 bit) or TFTPD64 (64 bit). It's free and very basic.

Hello.-

After reading release notes and some experiences in this forum, I am really worried about upgrading a SG300 firmware 1.1.2.0 to version 1.3.5.58. Release Notes points out that you have to update the boot loader before the firmware. However some users report that they had to reconfigure the switche after the upgrade.

My concern are.

- Is it necesary to boot the switche after upgrading the boot loader ?. This is not going to be a problem with the old firmware?.

- Can I apply the confirguration backup after the firmware upgrade or is necesary to reset to factory default and do it from scratch ?.

Thanks.
