16 Intel® RAID Controller RS25FB044 Hardware User’s Guide
Electrical Characteristics
All power is supplied to the Intel
®
RAID Controller RS25FB044 through the PCI
Express* 12 V rails and optionally from the +3.3 V and + 3.3Vaux 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 15 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: 5% to 90% 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 -45°C to 105°C (dry bulb)
• Relative humidity range: 5% to 90% non-condensing
• MTBF (electrical components) number: 2,00,000 hours at 40°C
Safety Characteristics
The Intel
®
RAID Controller RS25FB044 meets or exceeds the requirements of UL
flammability rating V0. Each bare board is marked with the supplier name or trademark,
type, and UL flammability rating.
