Each member of the stack will be updated with the latest firmware simply by updating the Master switch.
The screenshots below demonstrate how to copy the firmware to the Master using a TFTP server. The
stack needs access to a TFTP server on the network and the firmware file needs to be present in the
download folder of the TFTP server.
From the System > File Management > File Download page, select the appropriate settings. The most
common settings are shown here.
Click Apply. A warning will appear.
