It can provide up to 61.6 Watts of PoE power on the 8 Gigabit ports. ===== Hardware ===== * [[rtl838x|RTL8380M]] SoC * Macronix MX25L25635EMI (32MB flash) * (Nanya NT5CC256M8IN (256MB DDR3 SDRAM) * [[rtl8231|RTL8231]] GPIO extender to control the port LEDs, system LED and a reset button. * STMicro ARM microcontroller to manage PoE * 2x Broadcom BCM59111KMLG PoE controllers * STMicro PM8803 PoE-PD Interface and PWM Controller 2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules. Power is supplied via a 48V 1.75A (optional 54V 1.66A) barrel connector. A 3.3V TTL Serial header is found at JP1. Pins are marked G (Ground) R (Receive) T (Transmit) V (Voltage). Serial connection is via 115200 baud, 8N1. ==== Board details ==== ==== Pin-outs ==== === SoC UART === * J1.1: GND * J1.2: RX * J1.3: TX * J1.4: VCC, 3.3V ===== Firmware ===== The switch ships with U-Boot 2011.12 and ucLinux 2.6.19. It has a web interface for basic management, including firmware updates. The board identifies as RTL8380M_INTPHY_2FIB_1G_DEMO. ^ ^ Flash layout ^^^^^^^ | **Name** | u-boot | u-boot-env | device-info | config | log | firmware1 | firmware2 | | **Size** | 512k | 64k | 64k | 14M | 2M | 8M | 8M | ===== References ===== * [[https://www.engeniustech.com/engenius-products/managed-poe-network-switch-ews2910p/| Product support page ]]
