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 perform-
ance requires clean optics and connector ferrules.
1) Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable sup-
plier; low quality components can cause many hard-to-diagnose problems in an installation.
2) The manufacturer installs dust caps 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 rein-
stalled 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 (ESD) can cause damage to your add-in modules. Always observe the fol-
lowing 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 pro-
tection.
WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostat-
ic discharge damage. Do not handle these components directly unless you are a qualified service tech-
nician 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 prop-
er ESD bag. Do not slide the board over any surface.

The following precautions should be observed when installing chassis with DC power supplies.
1) Check nameplate ratings to assure there is no overloading of supply circuits that could have an
effect on overcurrent protection and supply wiring.
2) When installing 48V DC rated equipment, it must be installed only per the following conditions:
A) Connect the equipment to a 48V DC supply source that is electrically isolated form the alter-
nating current source. The 48V DC source is to be connected to a 48V DC SELV source.
B) Input wiring to terminal block must be routed and secured in such a manner that it is protect-
ed from damage and stress. Do not route wiring past sharp edges or moving parts.
C) A readily accessible disconnect device, with a 3mm minimum contact gap, shall be incorpo-
rated in the fixed wiring.
3) Grounding: reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct connections to the
branch circuit.

This equipment has been tested and found to comply with the limits for a Class B computing device, pur-
suant 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 man-
ual, 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.
This digital apparatus does not exceed the Class B 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 B prescrites dans le Règlement sur le brouillage radioélectrique publié par le
ministère des Communications du Canada.
