4 Sun Fire 880 Server Owner’s Guide • August 2001
The Sun Fire 880 server provides two serial communication ports, which are
accessed through a single, shared DB-25 connector located on the system rear panel.
The primary port is capable of both synchronous and asynchronous communication,
while the secondary port is asynchronous only. An optional serial port splitter cable
is required to access the secondary serial port. For more information, see “About the
Serial Ports” on page 79.
The rear panel also provides two Universal Serial Bus (USB) ports for connecting
USB peripheral devices such as modems, printers, scanners, digital cameras, or a
Sun Type 6 USB keyboard and mouse. The USB ports support both isochronous
mode and asynchronous mode and enable data transmission at speeds of 1.5 and 12
Mbps. For additional details, see “About the USB Ports” on page 80.
The local system console device can be either a standard ASCII character terminal or
a local graphics console. The ASCII terminal connects to one of the system’s two
serial ports, while a local graphics console requires installation of a PCI graphics
card, monitor, USB keyboard, and mouse. You can also administer the system from a
remote workstation connected to the Ethernet or from a Sun Remote System Control
(RSC) console.
RSC is a secure server management tool that lets you monitor and control your
server over modem lines or over a network. RSC provides remote system
administration for geographically distributed or physically inaccessible systems.
RSC software works in conjunction with the RSC card included in all Sun Fire 880
servers. The RSC card runs independently of the host server, and operates off of
5-volt standby power from the system’s power supplies. The card also includes a
battery that provides approximately 30 minutes of backup power in the event of a
power failure. Together these features allow RSC to serve as a “lights out”
management tool that continues to function even when the server operating system
goes offline, the server is powered off, or a power outage occurs.
Using RSC software, you can:
■
Access Solaris and OpenBoot PROM console functions remotely via the modem,
serial, and Ethernet ports on the RSC 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
■
Receive notification of server problems via email or pager, even in the event of a
power failure
■
Perform remote server reboot, power-on, and power-off functions on demand
For additional details, see “About the Remote System Control Card” on page 71 and
“About Sun Remote System Control Software” on page 150.
The basic system includes two 1120-watt power supplies with internal fans. Two
power supplies provide sufficient power for a maximally configured system. An
optional third power supply can be added to provide N + 1 redundancy, allowing
