Operating and Nonoperating Conditions for the Intel
®
RAID Controller
RS3SC008
For the Intel
®
RAID Controller RS3SC008, the operating (thermal and atmospheric)
conditions are as follows:
• Relative humidity range is 20 percent to 80 percent noncondensing.
• Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the
LSISAS3108 processor above the maximum ambient temperature.
• Temperature range: 10°C to +55°C
The parameters for the nonoperating (such as storage and transit) environment for these
controllers are as follows:
• Relative humidity range is 5 percent to 90 percent noncondensing.
• Temperature range: –40°C to +70°C
Power Supply Requirements for the Intel
®
RAID Module RMS3CC080
All power is supplied to the Intel
®
RAID Module RMS3CC080 through the PCIe 3.3V
rails and the 12V rail. On-board switching regulator circuitry operating from the 3.3V
rails and the 12V rail provides the necessary voltages. The following states determine the
typical current consumption of the controller:
• State 1: While sitting idle at the DOS prompt
• State 2: During a drive stress test
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± 9
percent (from PCI edge connector only). The following table lists the power supply for the
RAID controllers for these two states at the different voltages.
PCI Edge Connector State 1 State 2
3.3V supply 800mA 880mA
+12V supply 1000mA 1220mA
3.3V auxiliary supply 20mA 20mA
Total Power 14.95W 17.91W
