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.
