Chapter 3 Hardware Configuration 39
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 backup 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 enable 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.
The RSC card plugs into 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
■
56-Kbps modem port via an RJ-11 connector
■
10-Mbps Ethernet port via an RJ-45 twisted-pair Ethernet (TPE) connector

RSC Card Ports
All three RSC connection ports can be used simultaneously or individually disabled.
The modem supports regular asynchronous serial protocol, and can also support the
Point-to-Point Protocol (PPP). When running PPP, a standard internet TCP/IP
protocol stack is available over the modem interface.
Note – You must install the Solaris operating environment and the Sun Remote
System Control software prior to setting up an RSC console. For more information,
see “How to Monitor the System Using RSC” on page 195.
