Chapter 3 Hardware Installation and Upgrade
3.1 Jumpers and Connectors
The ARK-7480 Embedded Box Computer consists of an Advantech SBC (Single Board Computer) board that is housed in an aluminum top cover, a metal chassis with accessed bottom plate. Your CPU, HDD and SDRAM, are all readily accessible by removing the aluminum top cover. Any maintenance or hardware upgrades can be easily completed after removing the top cover or the accessed bottom plate.
Warning! Do not remove any mechanical parts, such as the top cover, or bottom plate until you have verified that no power is flowing within the Embed- ded Box Computer. Power must be switched off and the power cord must be unplugged. Every time you service the Embedded Box Computer, you should be aware of this.
3.2 Setting jumpers
You can configure your ARK-7480 to match the needs of your applica- tion by setting jumpers. A jumper is the simplest kind of electrical switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper, you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case, you would connect either pins 1 and 2 or pins 2 and 3.
