Preventing Electrostatic Discharge Damage to the Access Point
Many access point 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 verify 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 1 to 10 Mohms.
•
When handling any component that is removed from the chassis, verify that the
equipment end of your ESD strap is attached to one of the ESD points on the chassis.
•
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. If you are returning
a component, place it into an electrostatic bag before packing it.
