Electrical Characteristics

All power is supplied to the Intel
the board-to-board connector via PCI Express* 3.3 V rails.
The supply voltages are 3.3 V ± 9 percent from PCI edge connector only. The maximum
power for the +3.3 V rail is 18 W. The +3.3 V rail is used by the 3.3 V logic circuitry and
also used to generate the other required voltage rails of +1.0 V and +1.8 V.

Thermal and Atmospheric Characteristics

The thermal and atmospheric characteristics are:
•
Relative humidity range: 20% to 80% non-condensing
•
Maximum dew point temperature: 32°C
•
Airflow must be at least 200 linear feet per minute (SFPM) to avoid operating above
the maximum ambient temperature.
The storage and transit environment conditions are:
•
Temperature range from -30°C to 80°C (dry bulb)
•
Relative humidity range: 5% to 90% non-condensing
•
MTBF (electrical components) number: 298,900 hours at 40°C
