Remote System Control (RSC)
Remote System Control (RSC) software is a secure server management tool that lets
you monitor and control your server over modem lines or over a network. RSC
provides remote system administration for geographically distributed or physically
inaccessible systems. The RSC software works with the RSC card on the Sun Fire 880
system I/O board. The RSC card provides modem and private Ethernet connections
to a remote console, and a serial connection to a local alphanumeric terminal.
Once RSC is configured to manage your server, you can use it to run diagnostic tests,
view diagnostic and error messages, reboot your server, and display environmental
status information from a remote console. If the operating system is down, RSC can
send an email or pager alert about power failures, hardware failures, or other
important events that may be occurring on your server.
RSC provides the following features:
■
Remote system monitoring and error reporting (including diagnostic output)
■
Remote reboot, power-on, and power-off functions
■
Ability to monitor system environmental conditions remotely
■
Ability to run diagnostic tests from a remote console
■
Remote event notification for overtemperature conditions, power supply failures,
fatal system errors, or system crashes
■
Remote access to detailed event logs
■
Remote console functions via modem, Ethernet, or serial port
