17 ODROID-XU4 USER MANUALTypical home computing networkAfter preparing the boot media, it is theoretically possible to usea XU4 in a network disconnected from the Internet. However, manyuse cases require an always-ON functioning secure connection to theInternet. In either case, it is presumed you have a fully functioning in-tranet (i.e., the internal network within the home). There are numerousonline guides to setting up a secure network and as such, the setup ofsuch a network is beyond the scope of this guide.Preparing the Work AreaYour work area should be similar to the following:• A well-lit and ventilated area,• A flat-top desk spanning at least 2m x 1m with a height of 1m or appro-priate to optimize posture and minimize overall fatigue,• A freely available area of non-conductive surface of at least 1m x 1m,preferably covered by a well-grounded anti-static mat with you wearingthe grounding wristband/cable attached to the mat. This safeguards thehandling and placement of unprotected electronics such as XU4 board,etc., on this area,• A desktop with accessible monitor, keyboard/mouse or a laptop to preparethe boot-media for the XU4 and debug the XU4 bringup process,• If needed, a 4-port USB3 (USB2 compatible) hub attached to the com-puter within the reach of the free area - for easy image flashing using aUSB-based SD/eMMC module reader/writer and attaching the USB UARTdebug cable, and• A well-grounded surge-protector with 6 or more outlets, within reach ofthe free area.The above criteria will go a long way in ensuring a safe workspace foryou and your projects involving boards such as the XU4.Chapter 2
