Preventing Electrostatic Discharge Damage
Many switch 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 must be in the range of 1 through 10 Mohms.
■ When handling any component that is removed from the chassis, make sure the
equipment end of your ESD strap is attached to the electrostatic discharge points
on the rear panel of the chassis (see Figure 70 on page 139 and
Figure 71 on page 139).
■ Avoid contact between the component and your clothing. ESD voltages 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 72 on page 139). If you are returning a component, place it in an
electrostatic bag before packing it.
