Why does the status LED stays constant RED after powering on the unit?
This might indicate that the on-board CPU has not booted yet. Please check if the CPU button light is BLUE. If not, power on the CPU manually by pressing the CPU button once. The CPU button light should then turn blue.
If the CPU will not turn on after pressing the CPU button, please unplug the power supply from the unit and let it sit for at least 1 to 2 minutes. Then reconnect power and check if the CPU button turns blue.
