The bootloader doesn't show the full boot log. Note CFE seems to be blocked. It doesn't receive any key from the serial.

Basic configuration

Switch Ports (for VLANs)

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.
