Connecting the Power
The DA-682C provides dual power inputs using a terminal block, which is located on the rear panel. Connect the
power cord wires to the screws, and then tighten the screws. The Power LED will light up to indicate that power
is being supplied to the DA-682C, after which the BIOS will initialize the flash disk module, causing the Storage
LED to blink. It should take about 30 to 60 seconds for the operating system to complete the boot up process.
