-The Netgear GS728TPv2 is a 24 + 4-port Gigabit L2 switch with 24 gigabit ports. 4 Uplink ports are SFP cages which support 1000 Base-X tmini GBIC modules. It has an [[RTL8391M]] SoC. There are 3 RTL8218B PHYs and an unknown PHY for the SFP cages. One [[RTL8231]] GPIO extenders controls the port LEDs of the SFP cages.
+The Netgear GS728TPv2 is a 24 + 4-port Gigabit L2 switch with 24 gigabit ports.
-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.
-The 2 fans of the device are controlled by an MSP430 microcontroller: MSP430FR2311

-A Nuvoton M0516LDN on the a PoE control board controls 3 BCM5912100.
+Uplink ports are SFP cages which support 1000 Base-X tmini GBIC modules.
-A USB port provides USB 1.1 via a Maxim MAX3421E USB Peripheral/Host Controller with SPI Interface.
+Power is supplied via a 230 volt mains connector, with an internal power supply for 12 and 54 Volt.
-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.
+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.
-== OpenWRT Support ==
+==== Board details ====
-There is experimental hardware support for the device in OpenWRT. SFP does not work, nor does USB and fan control.
-== PCB ==
 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.
