Table 15. Power Supply for the Intel
®
RAID Controller RS3DC0x0
Note: The charging circuitry for the battery pack on the optional BBU battery-backed daughter
card uses +12V. If the BBU daughter card is mounted, the following power consumption
figures apply:
During trickle charging of the battery pack: Not applicable (no trickle charge for Li-ION).
During fast charging of the battery pack: 230mA in +12V current.
Operating and Nonoperating Conditions for the Intel
®
RAID Controller
RS3DC0x0
For the Intel
®
RAID Controller RS3DC0x0, 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 without battery backup unit
• Temperature range: +10°C to +45°C with battery backup unit
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 without battery backup unit
• Temperature range: 0°C to +45°C with battery backup unit
Power Supply Requirements for the Intel
®
RAID Controller RS3MC044
All power is supplied to the Intel
®
RAID Controller RS3MC044 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
PCI Edge Connector State 1 State 2
3.3V supply 793 mA 793 mA
+12V supply 915 mA 1090 mA
3.3V auxiliary supply 1 mA 1 mA
Total Power 13.95 W 16.15 W
