3.3.4.3 Power Supply Requirements for the MegaRAID SAS 9361 RAID Controllers

All power is supplied to the MegaRAID SAS 9361 RAID controllers through the PCIe 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: While sitting idle at the DOS® prompt

For the MegaRAID SAS 9361 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 LSISAS3108 processor above the

maximum ambient temperature

 Temperature range: 10 °C to +55 °C (with or without the CVFM04 module attached)

NOTE To maximize the lifespan of the CVPM module, keep the ambient

temperature as low as possible.

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

 State 3: Power on the controller with a deeply depleted CVPM module attached
