Gigabit Ethernet (with PoE Support) Interface

The Radxa Cubie A7A features an onboard Gigabit Ethernet interface with Power over Ethernet (PoE) support.

PoE functionality requires a PoE HAT and a PoE network switch to enable both power delivery and data transmission through a single Ethernet cable.

tip

For the exact location of the Ethernet interface, please refer to the interface description section in the Hardware Interface guide!

Ethernet

Connect the Cubie A7A's Ethernet port to your router using an Ethernet cable. Under normal circumstances, the Ethernet port LED will blink, indicating a successful connection.

Checking Network Interface Status

You can view network interface status and IP address information using the ip a command in the terminal.

radxa@device$

ip a

The terminal will display output similar to the following, where 192.168.2.106 is the IP address assigned by your router:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

PoE (Power over Ethernet)

To use PoE functionality, the Cubie A7A requires both a PoE HAT and a PoE network switch.

Once these requirements are met, connect the Cubie A7A's Gigabit Ethernet port to the PoE switch using an Ethernet cable.

Under normal operation:

• The board's power LED will illuminate, indicating successful power delivery
• The Ethernet port LED will blink, indicating an active network connection

Recommended PoE HAT

• 25W PoE+ HAT
