MegaRAID SAS RAID Controller Characteristics
Technical Specifications
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 BBU/a Cache Vault module)
— 0 °C to +45 °C (with BBU)
— 0 °C to +55 °C (with a Cache Vault module)
3.3.4.19 Power Supply Requirements for MegaRAID SAS 9280-4i4e, SAS 9280-8e, and SAS 9280DE-8e RAID Controllers
All power is supplied to the MegaRAID SAS 9280-4i4e, SAS 9280-8e, and SAS 9280DE-8e RAID controllers 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.
NOTE The MegaRAID SAS 9280 RAID controllers support the LSIiBBU07 unit
and the LSIiBBU08 unit, but the controllers do not support Cache Vault
modules.
NOTE The charging circuitry for the battery pack on the optional iBBU
battery-backed daughter card uses +12 V. If the iBBU daughter card is
mounted, the following power consumption figure applies in addition
to the +12-V consumption figures listed in the previous table:
 During fast charging of the battery pack: 230 mA in +12-V current.
3.3.4.20 Operating and Nonoperating Conditions for MegaRAID SAS 9280-4i4e, SAS 9280-8e, and SAS 9280DE-8e RAID
Controllers
The operating (thermal and atmospheric) conditions for the MegaRAID SAS 9280-4i4e, SAS 9280-8e, and
SAS 9280DE-8e RAID controllers 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 LSISAS2108 processor above the
maximum ambient temperature.
 Temperature range:
— +10 °C to +55 °C (without BBU)
— +10 °C to +45 °C (with BBU)
— +10 °C to +55 °C (with LSIiBBU08 mode 1 through 5)
