14 Sun Fire V890 Server Product Notes • September 2004
Software Issues
The following sections describe various software issues associated with the Sun Fire
V890 server product.
Sun Remote System Control (RSC) 2.2.2 Software
The Sun Fire V890 server comes with the system controller (SC) card installed. The
following list summarizes how the RSC 2.2.2 software and the system controller
hardware work together.
■ The SC card does not have an on-board modem. The modem/pager commands
and variables in the RSC 2.2.2 software do not work with the SC card. These
commands and variables are documented in the Sun Remote System Control (RSC)
2.2 User’s Guide, but they are not supported on the SC card in the Sun Fire V890
server.
■ The SC card does not have a system backup battery. It receives its power directly
from the server’s 5V standby power. The card runs even when the server is
powered down or on standby, as long as the server is plugged into an AC outlet.
For more information about using RSC 2.2.2 software with SC hardware, refer to the
Sun Fire V890 Server Owner’s Guide.
OpenBoot PROM Enhanced Diagnostics
OpenBoot PROM Version 4.15 comes with enhanced diagnostics that are enabled by
default. Full OpenBoot Diagnostics run at power-on. For more information about
these enhancements, the new and redefined configuration variables, and the new
standard (default) configuration, refer to OpenBoot PROM Enhancements for
Diagnostic Operation, which is available on the Sun Fire V890 Documentation CD
included with the Sun Fire V890 server.
For instance, when the OpenBoot PROM enhanced diagnostics are enabled, the
rsc-console connection diagnostic output gets sent to the server console without
issuing a warning message. When this occurs, the RSC console may appear not to
respond to RSC commands. This behavior can also happen when you are viewing
rsc-console output while the front panel keyswitch of the Sun Fire V890 server is
set to the Diagnostics position.
