Preventing Electrostatic Discharge Damage to a PTX5000 Packet Transport Switch
Many packet transport 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 should be in the range of 1 to 10 Mohms.
•
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 84 on page 223.
•
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 85
on page 223). If you are returning a component, place it in an electrostatic bag before
packing it.
