Administration Interface

Once you finish with the initial configuration, you will be taken to the web login page for access to the administration interface. The login page is in HTML, but there is also a flash page variant.


The administration interface looks old-fashioned, reminding us of QNAP's OS before its fully windowed iteration. While ThecusOS is snappy and includes all the necessary tools to get the job done, it should follow suit by evolving into a more polished and windowed interface with widget support and icons. For those of you looking to try ThecusOS, there is an online demo here.


On the left of the screen is the Menu Bar with all the options in ThecusOS. All its settings and functions are separated into groups to make them more readily accessible.


The "My favorite" shortcut allows you to designate often-used items, which will put them on the main screen. Next to it is a shortcut to shutdown or restart the server. The logout shortcut allows you to exit the administration interface. Beneath the News and Log shortcuts in the top-right corner is the language-selection menu; it includes many popular languages.


The Message Bar includes several icons for fast access to RAID, disk, fan, network, and temperature options, and any prelevant information pertaining to those options.

System Network

The Networking option contains all network parameters and allows you to change them. The DHCP/RADVD menu shows every available NIC state. If a static IP is used, the NIC can be configured to act as a DHCP/RADVD server.


The N5810 Pro has five Gigabit ports you can link to act as one, which increases network throughput. However, a switch that is compatible with the Link Aggregation Protocol is required.


Most network setting changes unfortunately require a lengthy reboot. Thecus should find a way to speed up the reboot process, or simply allow such network-specific settings to take place without a reboot.

System Information

You can find the NAS server's model number and firmware version in the General tab, or its up-time.


Click on Status to check on the state of various services or the hardware; CPU and memory activity, temperatures, network-transfer data, etc. If connected, you can also click on the second Status tab to check on the mini-UPS battery.

We installed the fully charged mini-UPS battery and removed the AC power cord. The system realized that the mains power had been removed after eight minutes (!), and the NAS was kept operational for another four minutes before the automatic shut-down procedure began. The battery had some juice left before the OS shut down; however, its role isn't to replace a large UPS that can last for a very long time, but to, rather, provide the user with the time it takes to safely shut the NAS down without losing any data.


The System Monitor does what its name implies: It monitors CPU and memory utilization, fan and temperature, network throughput, and lists all online users.


The Hardware Information tab looks like Windows' device manager: It displays information on the hardware installed. These include the CPU's model name, amount of RAM, and the USB-, Network-, and Disk controllers.
