ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand
alone units, containing electronic components. Always observe the following precautions
when installing or handling these kinds of products.
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component. If the
wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
3. Hold units by the edges; do not touch the electronic components or gold connectors.
4. After removal, always place boards on a grounded, static-free surface, ESD pad or in
a proper ESD bag. Do not slide the modules or stand-alone units over any surface.
WARNING!
Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do
not handle these components directly unless you are a qualified
service technician and use tools and techniques that conform to
accepted industry practices.
FIBER OPTIC CLEANING GUIDELINES
Fiber Optic transmitters and receivers are extremely susceptible to
contamination by particles of dirt or dust, which can obstruct the optic path and
cause performance degradation. Good system performance requires clean
optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber)
only from a reputable supplier; low-quality components can cause many
hard-to-diagnose problems in an installation.
2. Dust caps are installed at the factory to ensure factory-clean optical
devices. These protective caps should not be removed until the moment
of connecting the fiber cable to the device. Should it be necessary to
disconnect the fiber device, reinstall the protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic
bag or box so that, when reinstalled, they do not introduce any
contamination to the optics.
4. If you suspect that the optics have been contaminated, alternate
between blasting with clean, dry, compressed air and flushing with
methanol to remove particles of dirt.
