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.

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.

Note
Ports 3 and 4 are PoE only ports; do not
connect access point devices to these ports. The
ports can be used for infra-switch connection
using multiple an AP-Manager or data
interface.
