Table 3.6 Power Supply for the ServeRAID M5025 Controller
Note: +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 fast charging of the battery pack: 230mA in +12V

3.3.5 Operating and Non-operating Conditions
The operating (thermal and atmospheric) conditions for the ServeRAID
M5025 SAS/SATA controller 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


3.3.6 Safety Characteristics
The ServeRAID M5025 SAS/SATA controller meets or exceeds 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. The board is installed in a PCI Express bus slot, so all voltages
are lower than the SELV 42.4 V limit.
