====== EnGenius EWS2910P ======

The EWS2910P is a 8-port Gigabit PoE L2 switch with 2 SFP ports and a fan-less design.  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.
