MXK Hardware Installation Guide
•
Never attempt to service this product unless you are an authorized service
technician. Doing so can expose you to dangerous high-voltage points or
other risks and may result in injury or damage to the unit and void all
warranties.
•
The MXK system chassis requires a dedicated ground connection to the
building ground. If more than one MXK chassis is to be installed on a
rack, each one requires its own direct connection to the building ground.
•
Slots and openings in the product are provided for ventilation. To ensure
reliable operation of the product and to protect it from overheating, these
slots and openings must not be blocked or covered.

regulatory agencies and inspection authorities to ensure compliance.
•
A rare phenomenon can create a voltage potential between the earth
grounds of two or more buildings. If products installed in separate
buildings are interconnected, the voltage potential may cause a hazardous
condition. Consult a qualified electrical consultant to determine whether
or not this phenomenon exists and, if necessary, implement corrective
action prior to interconnecting the product.
•
Install the MXK in accordance with national and local electric codes to
meet central office requirements. Consult a qualified electrical consultant.
•
Invisible laser radiation may be emitted from the optical ports of the
MXK when no cable is connected. Avoid exposure and do not stare into
open apertures.

Prevent electrostatic damage

The system slot cards are susceptible to electrostatic discharge (ESD). ESD
can cause component failure and degraded system performance. Take
adequate precautions to prevent electrostatic discharge (ESD) with these
cards. Always wear a properly-grounded wrist strap or equivalent protection
when handling system cards.
Handle each card by its front panel or stiffener. Never touch the solder side,
connector pins, or components on a printed circuit card, and do not allow
cards to come into contact with one another.
To prevent damage to system cards when not in use, store and handle the
cards in their original antistatic bags. Keep the cards in their original packing
cartons to prevent damage caused by dust or dirt. Be sure to store the cards in
areas that are free from excessive humidity and temperatures.
