General Information
Access panels on the bottom of the Model 6600 Computer allow you to up-
grade memory or install an internal PC Card drive without having to com-
pletely disassemble the computer. These procedures require that you have
the proper equipment (listed below), that you observe all precautions and
that you adhere strictly to the procedures below. Failure to do so can result
in damage to the unit and may void your warranty or maintenance contracts.
Required Tools and Equipment
ESD Safety
The Model 6600 Computer contains electrostatic discharge sensitive (ESD)
components, which can be damaged by static voltages present in most envi-
ronments. Because of this, you must use a static-safe work station whenever
an access panel is removed to service internal components or subassemblies.
The battery compartment door and the PC card compartment door are not
considered "access" panels and this requirement does not apply to them.
The static-safe work station should consist (at minimum) of the following:
An approved, grounded, conductive work surface
"
A personal grounding device (such as a wrist strap grounded through
"
a 1-Megohm resistor)
A suitable grounding wire and clip to be attached to a metal shield
"
inside the computer
A wire and clip to ground any tools used in the following procedures
"
(tools used only when in contact with the operator's hand provide
sufficient ground for equipment that is otherwise electrically isolated)
Hand Tools
You will need a #1 Phillips screwdriver to open access panels and to remove
screws that secure subassemblies inside the computer. A machinist's scribe
will be needed to remove memory boards.
