Connecting the Terminal
Connect the terminal to the RS-232C connector marked J1 in the rear of the cabinet or to SP1.
When the Octel Overture 200/300 is initially powered up or restarted, you must establish the system baud
rate to print diagnostic messages. Refer to the following section.
If the system baud rate has already been established, the system header displays. Otherwise, press
Enter repeatedly (until the password prompt appears) to establish the baud rate.
Starting Up the System
When the Octel Overture 200/300 is loaded or reloaded, the CPU and VCU execute a Boot ROM
diagnostic. This section describes the results of this diagnostic.
Turn ON your terminal and set the baud rate to any of the valid rates (300, 600, 1200, 2400, 4800, 9600,
or 19200). At any of these baud rates, the Octel Overture 200/300 will print or display the diagnostic
status. Turn ON the power to the server.
Immediately following power up, press Enter repeatedly to establish the baud rate. If the baud rate is
not established at this time, the system header and diagnostic messages will not print.
