Chapter 3 Hardware Installation and
Upgrade
3.1 Jumpers and Connectors
The ARK-3380 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 plates. 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 and Rear Metal Face plates. 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 6.
3.2 Setting jumpers
You can configure your ARK-3380 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.
The jumper settings are schematically depicted in this manual as follows:
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 Computer, you should be aware of this.
