Netgear GS108Tv3

The GS108Tv3 is a 8-port Gigabit L2 switch with optional 802.3af PD power input on port 1.

• RTL8380M SoC
• Macronix MX25L25635F (32MB flash)
• Winbond W631GG8MB (128MB DDR3 SDRAM)
• RTL8231 GPIO extender to control the port LEDs, system LED and a reset button.

Power is supplied via a 12V 1A barrel connector or 802.3af.

A Serial header is found at J1. Pins are Vcc(3.3V, Square), TX, RX and GND. Serial connection is via 115200 baud, 8N1.

• J1.1: VCC, 3.3V (square pad)
• J1.2: RX
• J1.3: TX
• J1.4: GND

The switch ships with a bootloader based on Realtek's SDK for RTL83xx SoCs and Linux 3.18 based on Realtek's SDK. It has a web interface for basic management, including firmware updates. The web interface must be unlocked to gain access to all management functions. The unlock key is provided after registering the product with Netgear. The board identifies as RTL8393M_DEMO. But this is misleading. The SoC chip id is 83806800, which is RTL8380M_CHIP_ID according to sdk/include/hal/chipdef/chip.h in Realtek's SDK.

U-Boot is used as bootloader for this device, and has access to a modifiable u-boot-env partition. This can be used to store modified and custom environment variables.

Some realtek-specific commands are also available:

• rtk network on: Configure the ethernet hardware inside the bootloader (not enabled on boot).
