No. The RX-series thin clients are based on Raspberry Pi devices. By unplugging the power cord or power strip to shut it down, it can cause a variety of issues including corruption of the microSD card and file system.
It is important that your RX-series device get a clean shutdown. There are two easy ways to perform a clean shutdown to these devices:
The activity LED should flash 3 or 4 times just before powering off. It is then safe to remove the power cord.
