WARNING!
Integrated circuits and fiber optic components are extremely
susceptible to electro-static 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.
3) Hold boards by the edges only; do not touch the electronic components or gold
connectors.
4) After removal, always place the boards on a grounded, static-free surface, ESD
pad or in a proper ESD bag. Do not slide the board over any surface.
*Please contact Black Box for complete warranty, FCC and Safety Certification
information.

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 by the manufacturer to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of connecting the
fiber cable to the device. Assure that the fiber is properly terminated, polished and
free of any dust or dirt, and that the location is as free from dust and dirt as
possible.
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) Should it be necessary to disconnect the fiber device, reinstall the protective dust
caps.
5) 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.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to your add-in modules. Always
observe the following precautions when installing or handling an add-in module or any
board assembly.
1) Do not remove unit from its protective packaging until you’re ready to install it.
2) Wear an ESD wrist grounding strap before handling any module or component. If
you do not have a wrist strap, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
