Note – If you intend to use the Sun system’s serial port A rather than serial port B, edit this entry by replacing /dev/ttyb with /dev/ttya.

If you have redirected the system console to TTYB and want to change the system console settings back to use the serial port and network management ports, see “System Console OpenBoot Configuration Variable Settings” on page 17.

Accessing the System Console Through an Alphanumeric Terminal

Use this procedure when you access the system console by connecting the serial port of an alphanumeric terminal to the serial port of the server.

▼To Access the System Console Through an Alphanumeric Terminal

1.Attach one end of the serial cable to the alphanumeric terminal’s serial port.

Use a null modem serial cable, or an RJ-45 serial cable, and null modem adapter. Connect this cable to the terminal’s serial port connector.

2.Attach the opposite end of the serial cable to the serial port on the dongle cable.

3.Connect the alphanumeric terminal’s power cord to an AC outlet.

4.Set the alphanumeric terminal to receive:

■9600 baud

■8 bits

■No parity

■1 stop bit

■No handshake protocol

Refer to the documentation accompanying your terminal for information about how to configure the terminal.

You can issue system commands and view system messages using the alphanumeric terminal. Continue with your installation or diagnostic procedure, as needed. When you are finished, type the alphanumeric terminal’s escape sequence.

For more information about connecting to and using the ALOM system controller, refer to the Advanced Lights Out Management (ALOM) CMT v1.3 Guide.
