MegaRAID SAS RAID Controller Characteristics
Technical Specifications
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.
3.3.4.6 Operating and Nonoperating Conditions for the MegaRAID SAS 9260-16i RAID Controller
The operating (thermal and atmospheric) conditions for the MegaRAID SAS 9260-16i 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 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)
Operating ambient temperature: +55 °C. (The iBBU unit is not included in the limit because it is present remotely in
the system. You need to make sure that maximum operating ambient temperature around the LSIiBBU07 unit is 45 °C,
and 55 °C for the LSIiBBU08 unit.)
NOTE The operating ambient temperature of these RAID controllers can be
raised to +60 °C, provided the airflow over the controller is at least
300 LFPM.
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)
— +0 °C to +45 °C (with BBU)
