Safety precautions
Warning! Always completely disconnect the power cord
Removing the CPU
The SBC-676 all-in-one CPU module supports most Pentium III and
Celeron CPUs. The system's performance depends on the CPU you
choose. You can install or upgrade the CPU in the board's PGA
socket by following the procedures outlined below. If your system
has an existing CPU, you need to remove it before installing the
new CPU.
Removing a CPU
1. Disconnect power from the chassis, and unplug all connections
to the CPU card. Then, remove the CPU card from the chassis
by following the instructions in the user's manual for your
chassis.
2. Lift the CPU out of the PGA socket. The old chip may be
difficult to remove. You may find spray chip lubricant, designed
for pin-grid-array (PGA) devices, and a chip puller helpful.
These are available at electronics hobbyists' supply stores.
8 SBC-676 User Manual
from your chassis whenever you are working on it.
Do not make connections while the power is on
because sensitive electronic components can be
damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any
static charge before touching the CPU card.
Modern electronic devices are very sensitive to
static electric charges. Use a grounding wrist
strap at all times. Place all electronic components
on a static-dissipative surface or in a static-
shielded bag when they are not in the chassis.
