 Communication with the Poe-CPU happens via a serial port, connected to the main CPU's UART1. Optocouplers are used to isolate the two circuits from each other and the communication frames can be sniffed from J3 (3.3V, 19200 baud, 8n1). Communication with the Poe-CPU happens via a serial port, connected to the main CPU's UART1.

-To indicate the global device status, two LEDs are present on the front panel. One is labelled 'PoE Max', and is likely controlled directly by the PoE MCU. +To indicate the global device status, two LEDs are present on the front panel. One is labelled 'PoE Max', and is controlled directly by the PoE MCU. 
-The other is labeled 'Power', and is used to indicate the device status. This LED appears to be an RGB LED, although it is currently unclear how the three colours are controlled.+The other is labeled 'Power', and is used to indicate the device status. This LED a three-component RGB LED, driven by thre individual GPIO lines of the RTL8231.
 All ports have a two-pin bi-color LED, used to indicate the link status: green for 1000M, orange for 100M. These are driven by three SN74HC164 shift registers, using 20 of the 24 outputs available. All ports have a two-pin bi-color LED, used to indicate the link status: green for 1000M, orange for 100M. These are driven by three SN74HC164 shift registers, using 20 of the 24 outputs available.
 PoE status bi-color LEDs are also available, with green used to indicate the remote device is PoE powered, and orange to signal a PoE fault status. The PoE-status LEDs are driven by two SN74LV595A shift registers, also controlled by the PoE MCU. PoE status bi-color LEDs are also available, with green used to indicate the remote device is PoE powered, and orange to signal a PoE fault status.

-There is also a SN74LVC125A four-port tri-state buffer whose purpose is currently unknown.+A SN74LVC125A four-port tri-state buffer is used to for the reset signal fan-out, driven by internal GPIO13 (TP7).
