130 Sun Fire V490 Server Administration Guide • August 2004
Note – There are many other OpenBoot configuration variables, and although these
do not affect which hardware device is used as the system console, some of them
affect what diagnostic tests the system runs and what messages the system console
displays. For details, see “Controlling POST Diagnostics” on page 82.
3. Connect the RJ-45 serial cable and adapter.
The cable and adapter connect the Sun server’s ttyb serial port to the Sun Fire V490
system’s built-in ttya serial port. Pinouts, part numbers, and other details about the
serial cable and adapter are provided in the Sun Fire V490 Server Parts Installation and
Removal Guide.
4. Ensure that the /etc/remote file on the Sun server contains an entry for
hardwire.
Most releases of Solaris OS software shipped since 1992 contain an /etc/remote
file with the appropriate hardwire entry. However, if the Sun server is running an
older version of Solaris OS software, or if the /etc/remote file has been modified,
you may need to edit it. See “How to Modify the /etc/remote File” on page 131
for details.
5. In a terminal tool window on the Sun server, type:
The Sun server responds by displaying:
The terminal tool is now a tip window directed to the Sun Fire V490 system via the
Sun server’s ttyb port. This connection is established and maintained even if the
Sun Fire V490 system is completely powered off or just starting up.
What Next
Continue with your installation or diagnostic test session as appropriate. When you
are finished using the tip window, end your tip session by typing ~. (the tilde
symbol followed by a period) and exit the window. For more information about tip
commands, see the tip man page.
