LED Indicators

There are eight LEDs to indicate the status of the system power, power input 1,
power input 2, RTC battery, storage read/write, COM1~2 transmit/receive and PL1
for user's configurations.
 PWR: Green means normal, orange means standby.
 PWR1, PWR2: Red means power input source is abnormal, check the power
input source.
 RTC: Red means RTC battery abnormal, check the RTC battery.
 HDD, COM1~2: Flashing green means signals are being transmitted and
received.
 PL 1: User can configure the LED indicators' behavior through GPIO control.
