Web Interface: Upgrade the MicroRAPTOR using TFTP

This section will explain how to upgrade the MicroRAPTOR firmware. This process takes approximately 20 minutes to execute when there is a fast network connection between the TFTP server and the MicroRAPTOR.

To perform the tasks in this section, you will have already logged into the MicroRAPTOR via the Web UI. For all upgrades, it is recommended that user’s backup their current running configuration prior to commencing the upgrade process.

A TFTP server must be installed on a device with network connectivity to the MicroRAPTOR. There are a number of commercial and free TFTP server options available. For this example Tftpd64 was used as the server. It may be downloaded from this site: https://pjo2.github.io/tftpd64/. The switch has also be tested using SolarWinds TFTP Server: https://www.solarwinds.com/free-tools/free-tftp-server
