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
