Monitoring and Management With Remote
System Control Software
Remote System Control (RSC) is a secure server management tool that lets you
monitor and control your server over a serial port or a network connection. RSC
provides remote system administration for geographically distributed or physically
inaccessible systems. RSC software works in conjunction with the system controller
card included in all Sun Fire V890 servers. The system controller card runs
independently of the host server, and operates using 5-volt standby power from the
system’s power supplies. Together the hardware and software allow RSC to serve as
a “lights out” management tool that continues to function even when the server
operating system goes offline, or when the server is powered off.
Using RSC software, you can:
■ Access Solaris and OpenBoot™ PROM console functions remotely via the serial
and Ethernet ports on the system controller card
■ Run power-on self-test (POST) and OpenBoot Diagnostics from a remote console
■ Remotely monitor server environmental conditions, such as fan, temperature, and
power supply status, even when the server is offline
■ Perform remote server reboot, power-on, and power-off functions on demand
For additional details, see “About the System Controller Card and RSC Software” on
page 59 and “About Sun Remote System Control Software” on page 133.
Power
The basic system includes three 1629-watt output, 200–240-VAC input, power
supplies with internal fans. Two power supplies provide sufficient power for a
maximally configured system. The third power supply provides N+1 redundancy,
allowing the system to continue operating should any one of the power supplies fail.
Power supplies in a redundant configuration are hot-swappable, so that you can
remove and replace a faulty power supply without shutting down the operating
system or turning off the system power. For more information about the power
supplies, see “About Power Supplies” on page 61.
Rackmounting Options
The Sun Fire V890 server can be installed in any standard Electronic Industries
Association (EIA) 310-compliant 19-inch (48.3-cm) rack with at least 17 rack units
(29.8 inches, 75.6 cm) of available vertical mounting space and sufficient load-
