Firmware Upgrade

From the Firmware page, you can configure the system to download a new version of the management software. The switch can contain two software code

NOTE: The switch is shipped with one software code file installed (the filename is similar to PC3248_v1.00.00.00), which is set as the start- up file.
The Firmware page contains the following fields:
