Ethernet Port
The Power Mac G4 computer has a built-in 10/100 Mbps Ethernet port. The actual speed of the link is auto-negotiated between the computer's PHY device and the network bridge or router to which it is connected.
The connector for the Ethernet port is an RJ-45 connector on the back of the computer. Table 3-3 shows the signals and pins on the connector. The computer does not have a connector for a fiber-optic cable.
