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.

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.
Warnin g! 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.
