Chapter 3 Hardware Installation and
Upgrade
3.1 Jumpers and Connectors
The ARK-3384 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 Face plate. Your HDD,
SDRAM DIMM, are all readily accessible by removing the bottom cover.
Any maintenance or hardware upgrades can be easily completed after
removing the top cover, and front with rear metal face plates. 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 Chap-
ter 9.
3.2 Setting jumpers
You can configure your ARK-3384 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! Warning! Do not remove any mechanical parts,
such as the top cover, bottom cover and front/
rear face plate until you have verified that no
power is flowing within the Embedded Box Com-
puter. Power must be switched off and the power
cord must be unplugged. Every time you service
the Embedded Box Computer.
