GigE port and LED

The Gigabit Ethernet port is an RJ-45 connector 
form-factor. This port is designed so that 1500 VAC rms 
isolation (per the 802.3 specification) is met between 
chassis ground and any 48V/Ethernet signal.

3 & 4 POE

GigE Power-over-Ethernet 
(POE) ports

The Gigabit POE ports are RJ-45 connector form-factor. 
They provide a I2C communications channel between 
the PSE controller and host CPU TWSI bus #1. This 
interface supports the proper voltage isolation as defined 
by 802.3. The POE controller is configured to I2C 
address 0x40/41 (0100 000r/w).

The POE controller reset is driven from system reset. If 
software needs to reset the POE controller, it can do so 
over I2C.
