The GS1900-8HP v1 is an 8-port Gigabit L2 switch with a 70W of PoE power budget.

===== Hardware =====
  * [[rtl838x|RTL8380M]] SoC
  * Macronix MX25L12835F (16 MiB flash)
  * Nanya NT5TU128M8HE-AC (128 MiB DDR2 SDRAM)
  * 2 Broadcom BCM59111KMLG PoE controllers

Power is supplied via a 54V 2A barrel connector. At the right side behind the ventilation slits sits a hard reset button. The UART serial connector sits on the left side of the PCB, towards the bottom (case needs to be opened for serial access). Pins are labeled: VCC (3.3V), TX, RX, GND.
