Warning! Always completely disconnect the power cord
Caution!
The SBC-410 CPU card supports most 486 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.
1. Disconnect power from the chassis, and unplug all connec-
tions 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.

from your chassis whenever you are working on
it. Do not make connections while the power is
on, sensitive electronic components can be
damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.
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.
