Prevent Electrostatic Discharge Damage
91
Avoid spilling liquid onto the router chassis or onto any router component. Such an
action could cause electrical shock or damage the router.
Avoid touching uninsulated electrical wires or terminals that have not been disconnected
from their power source. Such an action could cause electrical shock.
Prevent Electrostatic Discharge Damage
Many router hardware components are sensitive to damage from static electricity. Some
components can be impaired by as little as 30 V. You can easily generate potentially
damaging static voltages when you handle plastic or foam packing material or if you move
components across plastic or carpet. To prevent intermittent or complete component
failures, always take ESD precautions:

failures, always take ESD precautions:
To minimize the potential for ESD damage, observe the following guidelines:
Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact
with your skin.
When handling any component that is removed from the chassis, make sure the
equipment end of your ESD strap is attached to one of the electrostatic discharge points
on the chassis, which are shown in Figure 1 and Figure 2.
on the chassis, which are shown in Figure 1 and Figure 2.
Avoid contact between the board and your clothing. ESD emitted from clothing can
damage components.
When removing or installing a component, always place it component-side up on an
antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 21). If
you are returning a component to the factory, immediately store the component in an
electrostatic bag.

For equipment safety, periodically check the resistance
value of the antistatic strap. The measurement should
range from 1 to 10 Mohms.
