2.5 Electrical Characteristics

The PCI Express* Specification requires that the 12-V rail and the 3.3-V rail have a voltage

tolerance of 8% and 9% respectively. The amount of power that an adapter card can use is also

limited.

All power is supplied to the Intel

RAID Controller RS2PI008 through the PCI Express* 3.3-V

rails and the 12-V rails. The on-board switching regulator circuitry, operating from these rails,

provides the necessary voltages. The following states determine the typical current consumption

of the controller:

 State 1: Battery is charging

 State 2: Battery is full

 State 3: Battery is discharging

The supply voltages are 12 V ± 8 percent from PCI edge connector only and 3.3 V ± 9 percent

from PCI edge connector only. The following table lists the power supply for the RAID controller

for each state at the different voltages:

PCI Express* +12 V PCI Express* +3.3 V PCI Express* +3.3 V Auxiliary Supply

State 1 950 mA 773 mA 30 mA

State 2 730 mA 773 mA 30 mA

State 3 733 mA 770 mA 30 mA
