About the Remote System Control Card
The Remote System Control (RSC) card enables access, monitoring, and control of
the Sun Fire 880 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 modem, serial, and Ethernet interfaces
that provide simultaneous access to the Sun Fire 880 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 power-on self-test (POST) and OpenBoot
Diagnostics.
The RSC card runs independently of the host server, and operates off of 5-volt
standby power from the system’s power supplies. It also includes a back-up battery
that enables the card to continue operating for up to 30 minutes in the event of a
power failure. 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 RSC card and RSC software to
serve as a “lights-out” management tool that continues to function even when the
server operating system goes offline, the system is powered off, or a power outage
occurs.
