System Console OpenBoot Configuration Variable Settings

Certain OpenBoot configuration variables control from where system console input is taken and to where its output is directed. The table below shows how to set these variables in order to use the serial port and network management port.

TABLE 1-3OpenBoot Configuration Variables That Affect the System Console

OpenBoot Configuration Variable Name	Serial and Network Management Ports

Note – The sc> prompt and POST messages are only available through the serial management port and network management port.

In addition to the OpenBoot configuration variables described in TABLE 1-3, there are other variables that affect and determine system behavior. These variables are discussed in more detail in Appendix A.
