Device components that are shipped in antistatic bags 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 grounding strap when you are handling components that are subject
to ESD damage, and make sure that it is in direct contact with your skin.
If a grounding strap is not available, hold the component in its antistatic bag (see
60 on page 181) in one hand and touch the exposed, bare metal of the device with the
other hand immediately before inserting the component into the device.
WARNING: 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 subject to ESD damage and that is removed
from the device, make sure the equipment end of your ESD strap is attached to the
ESD point on the chassis.
If no grounding strap is available, touch the exposed, bare metal of the device to ground
yourself before handling the component.
Avoid contact between the component that is subject to ESD damage and your clothing.
ESD voltages emitted from clothing can damage components.
When removing or installing a component that is subject to ESD damage, always place
it component-side up on an antistatic surface, in an antistatic card rack, or in an
antistatic bag (see Figure 60 on page
an antistatic bag before packing it.

CAUTION: ANSI/TIA/EIA-568 cables such as Category 5e and Category 6
can get electrostatically charged. To dissipate this charge, always ground
the cables to a suitable and safe earth ground before connecting them to the
system.
