LEDs
Power LED
This LED will be green when the system is powered on.
HDD LED
The HDD LED will flash orange when storage devices are being accessed.
Standby LED
This LED will be red when power is applied to the system board.
The lithium-ion battery is an auxiliary source of power when the main power is shut off. Two
of them provide power for the Static Random-Access memory (BAT 2 & 3) and one provides
power for the MCU and the system's CMOS memory (BAT 1). The optional BAT 4 connector
can be used to extend the retention time of the SRAM.
Safety Measures
• Danger of explosion if battery is incorrectly replaced.
• Replace only with the same or equivalent type recommend by the manufacturer.
• Dispose of used batteries according to local ordinance
.
