Chapter 3 Hardware Installation and
Upgrade
3.1 Jumpers and Connectors
The ARK-3381 Embedded Box Computer consists of a PC-based com-
puter that is housed in an aluminum top cover, a metal bottom case with
accessed bottom cover and Front/ Rear Metal Face plate. Your HDD,
SDRAM, are all readily accessible by removing the accessed bottom
cover. Any maintenance or hardware upgrades can be easily completed
after removing the top cover, and Front with Rear Metal Face plate. If you
are a systems integrator and need to know how to completely disassemble
the embedded box computer, you can find more useful information in
Chapter 6.
3.2 Setting jumpers
You can configure your ARK-3381 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 with rear face plate
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 Com-
puter, you should be aware of this.
