Intel® RAID Controller RS2WG160 Hardware User’s Guide 25
• State 3: During a RAID 5 stress test
• State 4: During a drive stress test while the BBU is under fast charging
The supply voltages are 12V ± 8 percent (from PCI
edge connector only) and 3.3V ± 9
percent (from PCI edge connector only). Below table lists the power supply for the
controller for each of the three states at the different voltages.
Table 10. Power Supply for the Controller
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
®
RAID Controller RS2WG160 meets or exceeds the requirements of UL
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
The RAID controller in this document is qualified to get Microsoft Windows* Winqual
certification (WHQL) at product launch.
