About this guide
Always follow ESD prevention procedures when removing and
replacing cards.
Wear an ESD-preventive wrist strap, ensuring that it makes good
skin contact. Connect the clip to an unpainted surface of the
chassis frame to safely channel unwanted ESD voltages
to ground.
To properly guard against ESD damage and shocks, the wrist
strap and cord must operate effectively. If no wrist strap is avail-
able, ground yourself by touching the metal part of the chassis.
