Chapter 3 Hardware Installation and
Upgrade
3.1 Jumpers and Connectors
The ARK-3383 Embedded Box Computer consists of a PC-based com-
puter that is housed in an aluminum top cover, a metal bottom case with
accessible bottom cover and front/ rear metal faceplates. The HDD, and
SDRAM DIMM, are all readily accessible by removing the easily acces-
sible bottom cover. Any maintenance or hardware upgrades can be easily
completed after removing the top cover, front and rear metal faceplates. If
you are a systems integrator and need to know how to completely disas-
semble the embedded box computer, you can find more useful informa-
tion in Chapter 8.
3.2 Setting jumpers
You can configure your ARK-3383 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.
Warning! Do not remove any mechanical parts, such as the
top cover, bottom cover and front/rear faceplates
until you have verified that no power is flowing
within the Embedded 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.
