FCC Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a Class A
computing device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which the user will be required to correct the interference at his own
expense.
Any changes or modifications not expressly approved by the manufacturer could void
the user’s authority to operate the equipment.
The use of non-shielded I/O cables may not guarantee compliance with FCC RFI
limits. This digital apparatus does not exceed the Class A limits for radio noise
emission from digital apparatus set out in the Radio Interference Regulation of the
Canadian Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de classe A prescrites dans le
Règlement sur le brouillage radioélectrique publié par le ministère des
Communications du Canada.
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 con -
nectors.
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.
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.
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.
