State and Description
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.

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.
