ARK-5280 User Manual 20
Chapter 3 Hardware Installation &
Upgrade
3.1 Jumpers and Connectors
The ARK-5280 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-5280 to match the needs of your application
by setting the 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.
The jumper settings are schematically depicted in this manual as follows:
Warning: Do not remove any mechanical parts, such as the
top cover, or the bottom plate until you have veri-
fied that no power is flowing within the Embedded
Box Computer. Power must be switched off and
the power cord must be unplugged.
