Cisco Systems 78 Manual De Usuario

Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies 
of different electrostatic potentials, such as an operator and a piece of electrical 
equipment. It occurs when electronic components are improperly handled, and it 
can damage equipment and impair electrical circuitry. Electrostatic discharge is 
more likely to occur with the combination of synthetic fibers and dry atmosphere.

Always use the following ESD-prevention procedures when removing and 
replacing components: 

Wear an ESD-preventive wrist strap that you provide, ensuring that it makes good 
skin contact. 

To properly guard against ESD damage and shocks, the wrist strap 
and cord must operate effectively. Always follow the guidelines in 
the preceding section, “Safety.”

Do not touch any exposed contact pins or connector shells of interface ports that 
do not have a cable attached. 

If cables are connected at one end only, do not touch the exposed pins at the 
unconnected end of the cable.

This router is intended for use in residential and commercial 
environments only.

Periodically check the resistance value of the antistatic strap, which 
should be between 1 and 10 megohms (Mohms).
