EASURES

Electrostatic Discharge (ESD)
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only
by their edges without any component and pin touching. After removing a board from its
protective wrapper or from the system, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the board
wrapper. Do not slide board over any surface.
Cooling and Airflow
Please be aware that slots and openings on the front and back side of the chassis are
designed for ventilation; to make sure reliable operation of your system and to protect it
from overheating, these openings must not be covered or blocked. The openings should
never be covered or blocked by placing the product on a bed, sofa, rug, or other similar
surface. This product should never be placed near or over a radiator or heat register, or in a
built-in installation unless proper ventilation is provided.
Laser Peripherals or Devices
Use certified and rated Laser Class I for Optical Transceiver product.
