Objective
The objective of this article is to upgrade the firmware on SRW WebView Switches. Firmware is software that a maker of a device puts out to allow for optimal usage of the device. The latest version of the firmware gives enhanced features over the current one, and upgrading firmware keeps the device up to date. A firmware upgrade can also fix bugs in the system and add new options. There are two ways to update the firmware: TFTP or HTTP. The firmware can also be backed up through the use of a TFTP server.
