Preventing Electrostatic Discharge Damage
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:
CAUTION: For safety, periodically check the resistance value of the ESD strap. The
measurement should be in the range of 1 to 10 Mohms.

Fire Safety Requirements

In the event of a fire emergency involving routers and other network equipment, the
safety of people is the primary concern. Establish procedures for protecting people
in the event of a fire emergency, provide safety training, and properly provision
fire-control equipment and fire extinguishers.

Safety Guidelines and Warnings
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 ESD points on the
chassis, which are shown in Figure 1 on page 6, Figure 2 on page 6, and
Figure 3 on page 7.
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 60 on page 130). If you are returning a component, place it in an
electrostatic bag before packing it.
