Fast Ethernet Management Interface
The Fast Ethernet port of the PowerPC 405 GP is used as a management interface. The ex-
ternal FE PHY device on the front board is connected to the RJ45 connector of the RTM.
The default setting of the AT8402's PHY is to operate in autonegotiation enabled mode, 10/100,
Full or Half duplex. The two LEDs of the RJ 45 connector are controlled by the CPLD.
The connection is established with a straight through Ethernet cable.
