2.5.2 Power Supervisor
This board supports a version of the Power Supervisor feature which adds protection to
the 5 VSB power rail by limiting potential electrical overstress events to a non-
destructive level.
2.5.3 Fan Header Current Capability
CAUTION
The processor fan must be connected to the processor fan header, not to a chassis fan
header. Connecting the processor fan to a chassis fan header may result in onboard
component damage that will halt fan operation.
Table 39 lists the current capabi
lity of the fan headers.
Table 39. Fan Header Current Capability
Fan Header Maximum Available Current
Processor fan 2.0 A
System fan 1.5 A
2.5.4 Add-in Board Considerations
The board is designed to provide 2 A (average) of current for each add-in board from
the +5 V rail. The total +5 V current draw for add-in boards for a fully loaded board
(all three expansion slots filled) must not exceed the system’s power supply +5 V
maximum current or 14 A in total.
