TP-Link T1600G-52PS
The TP-Link T1600G-52PS v4 48 + 4-port Gigabit L2 switch with PoE+.
Hardware
- RTL8393M SoC
- Winbond 25Q256JVFQ (32MB flash)
- SEC K4B2G1646 BYMA (256MB RAM)
4 Uplink ports are SFP cages which support 1000 Base-X tmini GBIC modules.
Power is supplied via a 230 volt mains connector, with an internal power supply for 12 Volt and PoE+.
The board does not have a console connector, but there is an unpopulated header at the left side (front-facing). The Pinout is either TX-RX-GND-VCC or RX-TX-GND-VCC, this needs to be checked again. The connection parameters are 38400 8N1.
Firmware
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.
OpenWrt Support
OpenWrt support is currently WiP. There is serial access to the bootloader and the stock firmware image has been successfully decrypted. However, a new U-Boot is required for development.
It might be possible to have upgrades from the stock web interface, but this depends on whether the RSA signature is actually verified or not - the relevant code is commented in the bootloader source code.
