Important Notes
• The power requirement of each product installed in this frame is indicated in the
Specifications section of the documentation provided with each card.
• For long-term reliability and increased product life, it is recommended that the total
dissipation of all modules installed in a frame should not exceed 16W total without the
CFM-8104A, and 40W total with the CFM-8104A.
• Frames without the CFM-8104A should be provided with one rack unit of empty space
above and below each frame for ventilation. Refer to the section “ Ventilation and
Cooling ” on page 2-4 for details on higher load applications requiring greater heat
dissipation.
