  LEDs:         Power, WAN, LAN1, LAN2, WLAN
  Buttons:      Reset
  UART:         through-hole on PCB
                pinout: RX, TX, GND, 3.3V
                settings: 115200n8

Flash instructions:
1. Connect the bundled PoE injector to power.
2. Connect the PC to the LAN1 or LAN2 port of the device.
3. Configure a static IP on the computer's Ethernet adapter:
     IP:      192.168.1.x (x = 2 to 254)
     Mask:    255.255.255.0
     Gateway: empty
     DNS:     empty
4. Connect a second Ethernet cable to the PoE port of the
   bundled injector.
5. Press and hold the reset button on the device.
6. While holding the reset button, plug the other end of the
   second Ethernet cable into the WAN port.
7. Wait at least 3 seconds, then release the reset button.
8. Browse to http://192.168.1.1: the MediaTek U-Boot System
   Recovery page should appear.
9. Click Upload and select the *-sysupgrade.bin firmware file.
10. After flashing completes, browse to http://192.168.1.1
    again: the LuCI login page should appear.
