12Gb/s Intel® RAID Controllers User Guide 31
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
RS3WC080
For the Intel
®
RAID Controller RS3WC080, the operating (thermal and atmospheric)
conditions are as follows:
•
Relative humidity range is 5 percent to 90 percent non-condensing.
•
Airflow must be at least 75 linear feet per minute (LFPM) to avoid operating the
LSISAS3008 processor above the maximum ambient temperature.
•
Temperature range: 0°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 non-condensing.
•
Temperature range: –45°C to +105°C
Power Supply Requirements for the Intel
®
RAID Controller RS3DC0x0
All power is supplied to the Intel
®
RAID Controller RS3DC0x0 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.

®
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:
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
