State 3. While sitting idle at the DOS prompt.
— Supply voltage = 12V +/- 8% (from PCI edge connector only)
— Supply voltage = 3.3V +/- 9% (from PCI edge connector only)
— Actual power consumption.
3.3V AUX. supply (BBU Applications only)
Note: +12V is used in the charging circuitry for the battery pack on the optional BBU Remote
card. If the BBU remote card is cable connected the following power consumption
figures apply:
1. During trickle charging of the battery pack: N/A (no trickle charge for Li-ION
2. During fast charging of the battery pack: 250mA rise in +12V current
Thermal and Atmospheric Characteristics
The maximum board temperature is limited by the LSI SAS2208 ROC Processor since it
uses the most power and will be the hottest component on the board.
•
SAS2208 maximum junction temperature: 115
•
Ambient temperature: maximum 60
•
Maximum 45
•
Airflow over SAS2208: 200 ft/min
•
Environmental humidity: 20% to 80% non-condensing
•
MTBF: greater than 300,000 hours
Safety Characteristics
The bare PC board shall meet or exceed the requirements of UL flammability rating V0.
The bare PC board shall also be marked with the supplier's name or trademark, type, and
UL flammability rating. The maximum electrical potential on the board will be 12.96V
potential difference, referenced from ground to +12V.
Operating Certifications
The RAID controller in this document is qualified to get Microsoft Windows* Winqual
certification (WHQL) at product launch.
