2. Attach an electrostatic discharge (ESD) grounding strap to your bare wris t and
connect the strap toone of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
“Preventing ElectrostaticDischarge Damage” on page 226.
3. Loosen the thumbscrew at the lower right corner of the PCG faceplate, using
a Phillips screwdriverif necessary.
4. Grasp the thumbscrewand slide the PCG about halfway out of the chassis.
CAUTION: Be careful to slide the PCG straight out of the chassis to avoid bending
any of the pins on the underside of the board.
5. Place one hand under the PCG to support it, slide itcompletely out of the
chassis, and place it on the antistatic mat or in the elec trostatic bag.
