It has 8 Gigabit ports, three 2.5/5/10GBit Ethernet ports and one SFP+ 10GBit uplink cages. {{ ::xgs1250.jpg?direct&600 |}} ===== Hardware ===== * [[rtl93xx|RTL9302B]] SoC * Macronix MX25L12833F (16MB flash) * Winbond W613GU6MB-12 (128MB DDR3 SDRAM) * [[RTL8231]] expander in shift register mode for the port LEDs * 8×GbE via RTL8218D PHY * 3× AQR113C NBase-T PHYs * One SFP+ uplink port Power is supplied via a 12V 2A standard barrel connector. At the right side behind the grid is UART serial connector. A Serial header can be connected to from the outside of the switch trough the airvents with a standard 2.54mm header. Pins are from top to bottom Vcc(3.3V), TX, RX and GND. Serial connection is via 115200 baud, 8N1. {{wiki:zyxel:xgs1250-12-top.jpg?200}} {{wiki:zyxel:xgs1250-12-bottom.jpg?200}} {{wiki:zyxel:xgs1250-12-rtl8231.jpg?200}} ==== JTAG ==== The board has an unpopulated eJTAG header J2. Similar to the [[GS1900-48]], nSRST and nTRST are configured such that the port is disabled. The following modifications make use of the eJTAG port possible: * Add jumper across R155 to connect the nSRST pin. * Move R156 to R151 to change the permanent pull-down into a pull-up. * (optional) Modify the heatsink and add a 2×7 pin header (see picture) The header's VIO pin is a voltage reference, tied to VCC via a 1k resistor (R153). This pin cannot be used to source current and is only provided as voltage reference. {{wiki:zyxel:xgs1250-12-jtag-heatsink.jpg?400}} ==== Port numbers ==== The RTL9302 SoC supports 24 GbE ports, and four 10G ports. Device ports 1-8 are switch ports 0-7. Device ports 9-12 are switch port 24-27. ^ Ports ^ LED index ^ LED comment ^ | 1-8 | 0 | Amber component of anti-parallel amber/lime LED.
