• 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.

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.
