About the System Controller Card
and RSC Software
The system controller (SC) card, combined with the Remote System Control (RSC)
software, enables access, monitoring, and control of the Sun Fire V890 server from a
remote location. It is a fully independent processor card with its own resident
firmware, power-on self-test (POST) diagnostics, and real-time operating system.
The card features serial and Ethernet interfaces that provide simultaneous access to
the Sun Fire V890 server for multiple RSC users. RSC users are provided secure
access to the system's Solaris and OpenBoot console functions and have full control
over POST and OpenBoot Diagnostics.
The system controller card runs independently of the host server, and operates on
5-volt standby power from the system's power supplies. The card features on-board
devices that interface with the system's environmental monitoring subsystem and
can automatically alert administrators to system problems. Together these features
allow the system controller card and RSC software to serve as a "lights-out"
management tool that continues to function even when the server operating system
goes offline or the system is powered off.
