b. Determine if a console login session can be established through a ttya connection.

If a working console connection can be established, the problem may not be a true hang but instead a network related problem. For suspected network problems, attempt to ping, rlogin, or telnet to another system that is on the same sub-network, hub, or router that the system is on. If NFS services are served by the affected system, determine if NFS activity is present on other systems.

2.If there are no responding login sessions, record the state of the system LEDs.

The system LEDs may indicate a hardware failure in the system. Refer to your Sun Fire 880 Server Owner’s Guide for more information on system LEDs.

3.Attempt to bring the system to the ok prompt by issuing the Stop-Acommand from your keyboard.

The Stop-Acommand attempts to bring a system with a standard or USB keyboard to the ok prompt. For more information about system keyboards, see “About OpenBoot Emergency Procedures” in the Sun Fire 880 Server Owner’s Guide.

a.If the system responds to the Stop-Acommand, issue the printenv command to display the OpenBoot configuration variables.

For more information about OpenBoot configuration variables, see “About POST Diagnostics” in the Sun Fire 880 Server Service Manual.

b.Set the diag-switchvariable to true and the diag-levelvariable to max.

4.Issue the sync command to obtain a crash (core) dump file.

Saved core dump files provide invaluable information to your support provider to aid in diagnosing any system problems. For further information about core dump files, see “Managing System Crash Information” in the Solaris System Administration Guide.

The system will reboot automatically after issuing the sync command, provided that the OpenBoot configuration variable is set to autoboot (the default value).

5.If you were not able to bring the system to the ok prompt, place the security keyswitch to the Diagnostics position.

This forces the system to run POST and OpenBoot diagnostics during system startup.

a.Press the system Power button for five seconds. This causes an immediate hardware shutdown.

b.Wait at least 30 seconds; then power on the system by pressing the system Power button.

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.
