FIGURE 3-3 Sun System Controller ( SC) Card
The SC card features serial and Ethernet interfaces that provide simultaneous access
to the Sun Fire V490 server for multiple RSC software users. RSC software 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 SC card runs independently of the host server, and operates off of 5V 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
enable the SC 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 when
the system is powered off.
The SC card plugs in to a dedicated slot on the system PCI riser board and provides
the following ports (listed in order from top to bottom, as shown in
FIGURE 3-4 )
through an opening in the system’s back panel:
■
Serial communication port via an RJ-45 connector
■
10-Mbps Ethernet port via an RJ-45 twisted-pair Ethernet (TPE) connector
