Technical Specifications 3-7
The supply voltages are 12V ± 8 percent (from PCI edge connector only)
and
3.3V ± - 9 percent (from PCI edge connector only). Table 3.6 lists
the power supply for the controller for each of the three states at the
different voltages.
+12V is used in the charging circuitry for the battery pack
on the optional iBBU battery-backed daughter card. If the
iBBU daughter card is mounted, the following power
consumption figures apply:
– During trickle charging of the battery pack: N/A (no
trickle charge for Li-ION)
– During fast charging of the battery pack: 230mA in +12V

3.3.5 Operating and Non-operating Conditions
For the ServeRAID-MR10i controller, the operating (thermal and
atmospheric) conditions are:
•
Relative humidity range is 5% to 90% noncondensing
•
Airflow must be at least 200 linear feet per minute (LFPM) to avoid
operating the Intel IOP333 processor above the maximum
ambient temperature
The parameters for the non-operating (such as storage and transit)
environment for the ServeRAID-MR10i controller are:
•
Temperature range:
−
30
°
C to +80
°
C without the battery backup unit
•
Temperature range: 0
°
C to +45
°
C with the iBBU battery backup
