Once logged into the web interface you are greeted with a screen that has the manufacturer, model, firmware level, and uptime. Across the top of the interface are the various settings for the system. Finding a particular setting is fairly easy; the interface is nicely laid out. I forgot to get a screen shot of it, but our unit had come with firmware v2.01.04. After checking on the Thecus website there was new firmware released for it, v2.01.07.
To upgrade the firmware you go to the website and download the update to your PC. Then, in the N4100PRO’s web interface under System you will find the Firmware Upgrade. Browse to the file you downloaded and click “Apply” and the system does the rest.
When the process starts you will get a warning with a progress meter. The warning tells you not to turn the unit off during the updating process. When the update is done the system needs to reboot; this only takes a minute or so. Once the system is back up and running you can log back in and set up the array.
