•
State 1: No BBU, eight SAS ports active
•
State 2: Eight SAS ports active, remote iBBU charging
•
State 3: Eight SAS ports active, both remote iBBU and iTBBU
charging
The supply voltages are 12V ± 8 percent (from the PCI edge connector
only) and 3.3V ± 9 percent (from PCI edge connector only). The 3.3V
auxiliary supply measurement is for the board powered down in the BBU
mode with an iTBBU installed.
Table 3.12 lists the power supply for the
RAID controller for each of the three states at the different voltages.

3.3.5 Operating and Non-operating Conditions
For the MegaRAID 1078-based SAS RAID controllers, the operating
(thermal and atmospheric) conditions are:
•
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 processor above the maximum ambient temperature
The parameters for the non-operating (such as storage and transit)
environment for the MegaRAID 1078-based SAS RAID controllers are:
•
Temperature range:
−30° C to +80° C without the battery backup unit
•
Temperature range: 0
° C to +45° C with the battery backup unit
3.3.6 Safety Characteristics
All MegaRAID 1078-based 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 PCI Express bus slot, all voltages are
lower than the SELV 42.4V limit.
