Power LEDs (LED1101, LED1102)
There are two power status LEDs on the EP6 board.
The LED1101 indicates the presence of 5V power on the EP6 board. This LED is off when
the system goes in the sleep mode. A light pipe is used to bring the light on to the front
panel.
The LED1102 ind5V standby. As soon as the internal 5V regulator starts working,
this 5V LED1102 remains on.
