Intel® Integrated RAID Module SROMBSASMR (AXXROMBSASMR) Technical Product Specification Hardware
2.5 Electrical Characteristics
All power is supplied to the Intel ® Integrated RAID Module SROMBSASMR through the board-
to-board connector via PCI Express* 3.3 V rails.
The supply voltages are 3.3 V ± 9 percent from PCI edge connector only. The maximum power
for the +3.3 V rail is 18 W. The +12 V rail is not provided by the base card. The +3.3 V rail is
used by the 3.3 V logic circuitry and also used to generate the other required voltage rails of
+1.5 V and +1.8 V. The +3.3 V auxiliary voltage is used to generate the +12 V standby for the
Intel
® RAID Smart Battery AXXRSBBU3.
The voltage level used in the charging circuitry for the battery pack on the optional Intel ® RAID
Smart Battery AXXRSBBU3 is +12 V. During fast charging of the battery pack, expected power
consumption is 230 mA rise in +12V current.

2.6.1.1 Safety Characteristics
The Intel ® Integrated RAID Module SROMBSASMR 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. For the boards installed in a PCI Express* bus slot, all voltages
are lower than the SELV 42.4 V limit.
