Manual Upgrade
For both HTTP and TFTP methods, the device will reboot itself into the downloader mode if the main appli-
cation is executing, and proceed with the ROM file download and permanent write of the application to the
device’s flash memory. During download of new firmware images, the LEDs on the SmartLink 4020 will flash
sequentially. Typically, HTTP downloads take about 5–10 minutes. After the download is completed, the
download status page will be displayed.
