Sun Microsystems 440 manual Accessing the System Console Through a Graphics Monitor

Page 21

If you have directed the system console to ttyb, you cannot use this port for any other serial device.

In a default configuration, the serial management and network management ports allow you to open up to four additional windows through which you can view, but not affect, system console activity. You cannot open these windows if the system console is redirected to ttyb or to a graphics card’s port.

In a default configuration, the serial management and network management ports allow you to switch between viewing system console and system controller output on the same device by typing a simple escape sequence or command. The escape sequence and command do not work if the system console is redirected to ttyb or to a graphics card’s port.

The system controller keeps a log of console messages, but some messages are not logged if the system console is redirected to ttyb or to a graphic card’s port. The omitted information could be important if you need to contact Sun customer service with a problem.

For all the preceding reasons, the best practice is to leave the system console in its default configuration.

You change the system console configuration by setting OpenBoot configuration variables. See “System Console OpenBoot Configuration Variable Settings” on page 31.

You can also set OpenBoot configuration variables using the ALOM system controller. For details, refer to the Advanced Lights Out Manager User’s Guide (817- 5481-xx).

Accessing the System Console Through a Graphics Monitor

The Netra 440 server is shipped without a mouse, keyboard, monitor, or frame buffer for the display of bitmapped graphics. To install a graphics monitor on the server, you must install a frame buffer card into a PCI slot, and attach a monitor, mouse, and keyboard to the appropriate back panel ports.

After starting the system, you might need to install the correct software driver for the PCI card you have installed. For detailed hardware instructions, see “Accessing the System Console Through a Local Graphics Monitor” on page 29.

Note – POST diagnostics cannot display status and error messages to a local graphics monitor.
