Preventing Electrostatic Discharge Damage
Many router components can be damaged by static electricity. Not exercising the
proper electrostatic discharge (ESD) precautions can result in intermittent or
complete component failures. To minimize the potential for ESD damage, always
use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it
makes good skin contact.
Note Check the resistance value of the ESD-preventive strap periodically. The
measurement should be between 1 and 10 megohms.
Before you perform any of the procedures in this guide, attach an ESD-preventive
strap to your wrist and connect the leash to the chassis or to another grounded,
bare metal surface as shown in Figure 2-1.
