#3. Power Fault Connector (MCU Power On

Switch)

In normal operating mode, power is governed

by the MCU (Micro Controller Unit). As a ser-

curity measure, the switch must be depressed

for at least four seconds to power down the

system.

In the case of an unexpeceted loss of power,

the MCU will return the system to the power

state it was in at the time when power was

lost.

system status.

The 3-pin connectors, designated Fan1 and

Fan2, provide power to the fans.

Since the system will use the power card

instead of a motherboard, two fans provide

sufcient cooling for the server.
