6.Use the POST and OpenBoot diagnostics tools to diagnose system problems.

When the system initiates the startup sequence, it will run POST and OpenBoot diagnostics during system startup. For more information about these tools, see “Diagnostics and Troubleshooting” in the Sun Fire 880 Server Service Manual.

7.If the system is able to reboot, review the contents of /var/adm/messages for more information about the system’s state. Look for the following information.

Any large gaps in the time stamp of Solaris or application messages.

Warning messages about any hardware or software components.

Information from last root logins to determine if any system administrators can add any comments about the system state at the time of the hang.

Supported Sun Rack for the Sun Fire 880

Currently, the only supported Sun rack for the Sun Fire 880 server is the StorEdge Expansion Rack, Sun part number SG-XARY030A. An optional door, Sun part number X9818A, is available for this rack.

Sun Fire 880 Server Rackmounting Caution Reminder

Caution As stated in the Sun Fire 880 Server Rackmounting Guide, do not attempt to lift the server until you remove all CPU/Memory boards, all power supplies, all CPU fan trays, and all I/O fan trays. Once these components are removed, four persons are required to lift the system.

The four lifting handles included in the rackmounting kit are not designed to support the weight of a fully populated system.

880 specifications

The Sun Microsystems 880 is a prominent series of workstations and servers that played a significant role in the computing landscape during the late 1980s and early 1990s. It was known for its innovative technologies and robust performance, making it a favored choice for both developers and enterprises. The 880 series was powered by the SPARC (Scalable Processor ARChitecture) architecture developed by Sun, which provided enhanced speed and efficiency.

One of the standout features of the Sun 880 was its multiprocessing capability, allowing multiple processors to work simultaneously. This capability ensured high performance for demanding tasks, making it ideal for applications in scientific research, graphics, and large databases. The architecture supported a wide range of operating systems, with SunOS being the most notable, providing a stable and powerful environment for users.

The Sun 880 also incorporated advanced memory management features, including support for virtual memory, which allowed for more effective use of system resources. Users could run multiple applications simultaneously without compromising system performance. The system architecture was designed to handle large amounts of RAM, which was essential for memory-intensive applications, further enhancing its suitability for professional use.

Another characteristic of the Sun 880 series was its modular design, which allowed for easy upgrades and maintenance. This modular approach meant that users could customize their systems according to their specific needs, whether that involved adding more memory, upgrading processors, or incorporating additional storage solutions. The high flexibility made it appealing to businesses that required tailored solutions.

In terms of connectivity, the Sun 880 featured a variety of ports and interfaces, enabling integration with various peripheral devices. This made it possible to connect printers, scanners, and other essential tools, facilitating seamless operation in office environments.

The Sun 880's impressive combination of processing power, expandability, and superior memory management made it a cornerstone in the evolution of workstations and servers during its time. As technology progressed, the Sun 880 helped pave the way for subsequent generations of computing systems, leaving a lasting legacy in the realm of high-performance computing. The architecture and design principles laid down by the Sun 880 continue to influence modern computing technologies today.
