NSTALLING AND UPGRADING
To upgrade to a higher power Pentium CPU, simply remove the old CPU and install to a
new one; be sure to set the jumpers for the new CPU type and speed.
WARNING!
Disconnect the power cord from your system when you intend to work on
it or you plan to open the chassis of your IPC. Do not make connections
when the power is turned on as sensitive electronic components can be
damaged by the sudden rush of power. Please only allow experienced
electronics technicians to do this job.
STATIC ELECTRICITY PRECAUTION!
Caution! Computer components are very sensitive to damage from static
electric discharge. Always ground yourself to remove static charge
build-up before touching the boards in the computer. Use a grounding
wrist strap at all time. Place all electronic components on the anti-static
pad for static-dissipation or in a static-shielded bag when they are not in
the chassis.

In order to select the operation modes of your system, configure and set the jumpers on
the your SBC to match the need of your application. To set a jumper, a black plastic
cap containing metal contacts is placed over the jumper pins as designated by the
required configuration as listed in this section. A jumper is said to be “ on ” or “ 1-2 ”
when the black cap has been placed on two of its pins, as show in the figure below:
A pair of needle-nose pliers is recommended when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local sales representative before you make any changes. In general, you simply need
a standard cable to make most connections.
