Warning
The adapter is being installed in a system that operates with
voltages that can be lethal. Before you remove the cover of your
system, you must observe the following precautions to protect
yourself and to prevent damage to the system components:
- Remove any metallic objects or jewelry from your hands and wrists.
- Use only insulated and non-conducting tools.
- Verify that the system is powered off and unplugged before
accessing the internal components.
- Installation or removal of adapters must be performed in a static-
free environment. The use of a properly grounded wrist strap or
other personal antistatic device and an antistatic mat is strongly
recommended.  E39
