Technical Specifications
3.3.4.2 Operating and Nonoperating Conditions for MegaRAID SAS 9240 RAID Controllers
For the MegaRAID SAS 9240 RAID controllers, 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 LSISAS2008 processor above the
maximum ambient temperature.
 Temperature range: +10 °C to +60 °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: –30 °C to +80 °C.
3.3.4.3 Power Supply Requirements for MegaRAID SAS 9260 RAID Controllers
All power is supplied to the MegaRAID SAS 9260-4i, SAS 9260-8i, SAS 9260CV-4i, SAS 9260CV-8i, and SAS 9260DE-8i
RAID controllers through the PCI Express 3.3V rails and the 12V rail. Onboard 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: During a hard reset
 State 2: During a drive stress test
 State 3: While sitting idle at the DOS prompt
The supply voltages are 12V ± 8 percent (from the PCI edge connector only) and 3.3V ± 9 percent (from the PCI edge
connector only). The following table lists the power supply for the RAID controllers for each of the three states at the
different voltages.
3.3.4.4 Operating and Nonoperating Conditions for MegaRAID SAS 9260 RAID Controllers
For the MegaRAID SAS 9260-4i, SAS 9260-8i, SAS 9260CV-4i, SAS 9260CV-8i, and SAS 9260DE-8i RAID controllers, the
operating (thermal and atmospheric) conditions are as follows:
 Relative humidity range is 5 percent to 90 percent noncondensing (20 percent to 80 percent noncondensing for
the RAID controllers)
 Airflow must be at least 200 linear feet per minute (LFPM) to avoid operating the LSISAS2108 processor above the
maximum ambient temperature
 Temperature range: +10 °C to +60 °C without the battery backup unit
 Temperature range: +10 °C to +45 °C with the iBBU battery backup

PCI Edge Connector State 1 State 2 State 3
3.3V supply 553mA 713mA 557mA
+12V supply 773mA 923mA 710mA
3.3V auxiliary supply N/A N/A N/A
Total power 11.047W 13.362W 10.307W
NOTE The charging circuitry for the battery pack on the optional iBBU 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.
