Preventing Electrostatic Discharge Damage

Many services gateway 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.

Preventing Electrostatic Discharge Damage
Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact
with your skin.
When handling any component that has been removed from the chassis, verify
that the equipment end of your ESD strap is attached to one of the ESD points
on the chassis, which are shown in Figure 5 on page 9, and Figure 6 on page 10.
