Preventing Electrostatic Discharge Damage to an ACX1000 or ACX1100 Router
Many router hardware components are sensitive to damage from static electricity. Some
components can be impaired by voltages as low as 30 V. You can easily generate
potentially damaging static voltages whenever you handle plastic or foam packing
material or if you move components across plastic or carpets. Observe the following
guidelines to minimize the potential for electrostatic discharge (ESD) damage, which
can cause intermittent or complete component failures:
•
Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact
with your skin.
CAUTION: For safety, periodically check the resistance value of the ESD
strap. The measurement should be in the range of from 1 to 10 Mohms.
•
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 (see Figure 35 on page 158).
•
Avoid contact between the component and your clothing. ESD voltages emitted from
clothing can still 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 36 on page 159). If you are returning a component, place it in an electrostatic bag
before packing it.
