MegaRAID SAS RAID Controller Characteristics
Technical Specifications
3.3.4.31 Power Supply Requirements for the MegaRAID SAS 9286CV-8eCC RAID Controller
All power is supplied to the MegaRAID SAS 9286CV-8eCC RAID controller through the PCIe 3.3-V rails and the 12-V rail.
Onboard switching regulator circuitry operating from the 3.3-V rails and the 12-V 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 disk stress test
 State 3: While sitting idle at the DOS prompt
The supply voltages are 12 V ± 8 percent (from the PCI edge connector only) and 3.3 V ± 9 percent (from the PCI edge
connector only). The following table lists the power supply for the controller for each of the three states at the
different voltages.
3.3.4.32 Operating and Nonoperating Conditions for the MegaRAID SAS 9286CV-8eCC RAID Controller
The operating (thermal and atmospheric) conditions for the MegaRAID SAS 9286CV-8eCC RAID controller 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 LSISAS2208 processor above the
maximum ambient temperature.
 Temperature range: +10 °C to +55 °C (with or without a Cache Vault module)
NOTE The MegaRAID SAS 9286CV-8eCC RAID controller supports the
CVFM03 module and the CVPM02 module, but the controller does not
support BBU units.
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 a Cache Vault module)
— 0 °C to +55 °C (with a Cache Vault module)
3.3.5 Safety Characteristics
All 6Gb/s MegaRAID SAS RAID controllers meet or exceed the requirements of UL flammability rating 94 V0. Each bare
board is also marked with the supplier name or trademark, type, and UL flammability rating. For the boards installed
in a PCIe bus slot, all voltages are lower than the SELV 42.4V limit.
