The switch s a 24 + 4-port Gigabit L2 switch with 24 gigabit ports with up to 193 Watts on P or 370Watts on MP of PoE+ power on the 24 Gigabit ports. The only difference between the P and MP models appears to be in the provided power supply.

  • Macronix MX25L25635F 32MB flash
  • Nanya NT5CC128M8GN-D1 128MB DDR3 SDRAM
  • Realtek RTL8231 GPIO extender/LED driver
  • Nuvoton ARM microcontroller
  • Broadcom BCM59121B0KMLG PoE controllers

4 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules shared with 4 RJ-45 ports

Power is supplied via a 100-240V Type C13 connector.

A unpopulated serial header is found at J12. Pins are Vcc(3.3V, Square), TX, RX and GND. Serial connection is via 115200 baud, 8N1.

There appears to be a unpopulated 14-pin JTAG available at J3.


  • J12.1: VCC, 3.3V (square pad)
  • J12.2: TX
  • J12.3: RX
  • J12.4: GND
