10/100 BASE T Ports

2

The two RJ-45 ports labeled 10/100 BASE T provide the 10BaseT/100BaseTX Ethernet LAN interface. These connectors are top- labeled with the designation LAN1 and LAN2.

DEBUG Port

The RJ-45 port labeled DEBUG provides an RS232 serial communications interface, based on TL16C550 Universal Asynchronous Receiver/Transmitter (UART) controller chip. It is asynchronous only. For additional information on pin assignments, refer to Chapter 5, Pin Assignments.

The DEBUG port may be used for connecting a terminal to the MVME5100 to serve as the firmware console for the factory installed debugger, PPCBug. The port is configured as follows:

❏8 bits per character

❏1 stop bit per character

❏Parity disabled (no parity)

❏Baud rate = 9600 baud (default baud rate at power-up)

After power-up, the baud rate of the DEBUG port can be reconfigured by using the debugger’s Port Format (PF) command.

System Powerup

After you have verified that all necessary hardware preparation is done, that all connections were made correctly, and that the installation is complete, you can power up the system.
