76 Sun Fire V480 Server Administration Guide • February 2002
Using the System Console
To use the system console, you need some means of getting data into and out of the
computer, which means attaching some kind of hardware to the server. Initially, you
may have to configure that hardware, and load and configure appropriate software
as well.
Instructions for attaching and configuring hardware to access the system console are
given in Chapter 7. The following subsections, “Default System Console
Configuration” beginning on page 76 and “Alternative System Console
Configuration” beginning on page 76, provide background information and
references to instructions appropriate for the particular device you choose to access
the system console.
Default System Console Configuration
On Sun Fire V480 servers, the system console comes preconfigured to allow input
and output only by means of an alphanumeric terminal or
tip
line attached to the
system’s built-in serial port,
ttya
. This provides for secure access at the installation
site.
Using a
tip
line may be preferable to connecting an alphanumeric terminal, since
tip
lets you use windowing and operating system features.
For instructions on setting up an alphanumeric terminal as the system console, see
“How to Set Up an Alphanumeric Terminal as the System Console” beginning on
page 139.
For instructions on accessing the system console via a
tip
line, see “How to Access
the System Console via tip Connection” beginning on page 134.
Alternative System Console Configuration
After initial system installation , you can configure the system console to communicate
via alternative devices, including a local graphics terminal, or Sun Remote System
Control (RSC).
To use a device other than the built-in serial port as the system console, you need to
reset certain of the system’s OpenBoot configuration variables and properly install
and configure the device in question.
