4 Uplink ports are SFP cages which support 1000 Base-X tmini GBIC modules.

Power is supplied via a 230 volt mains connector, with an internal power supply for 12 and 54 Volt.

The board has a hard reset switch SW1, which is is not reachable from the outside. CN1 provides a 3.3V UART, the pins are marked. From CN1 a cable leads to a conversion pcb for a 12V RS232 serial connector, which is accessible on the router's back.

There are 5 PCBs, a main PCB, a power supply, a PCB for PoE, a UART-RS232 converter, and a smaller PCB for Leds, USB-port and buttons.

PoE injector board

It ships with a bootloader based on Realtek's SDK for RTL83xx SoCs and Linux 3.18 based on Realtek's second generation SDK. It has a web interface for all management functions.

There is experimental hardware support for the device in OpenWrt. SFP does not work, nor does USB and fan control.
