| - | 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' | + | |
