Thermal and Atmospheric Characteristics
The thermal and atmospheric characteristics are:
•
Relative humidity range: 5% to 90% non-condensing
•
Airflow provided by server system or server chassis must be at least 200 linear feet
per minute (SFPM) to avoid operating above the maximum ambient temperature.
•
Temperature range: +10 °C to +60 °C without battery backup unit.
•
Temperature range: +10 °C to +44.5 °C with battery backup unit.
The storage and transit environment conditions are:
•
Temperature range: −30 °C to +80 °C without battery backup unit.
•
Temperature range: 0 °C to +45 °C with battery backup unit.
•
MTBF (electrical components) number: 494116 hours at 40°C
Safety Characteristics
The Intel
flammability rating 94 V0. Each bare board is also marked with the supplier name or
trademark, type, and UL flammability rating. For the boards installed in a PCI Express bus
slot, all voltages are lower than the SELV 42.4V limit.
Operating Certifications
