2.Use the output from the POST tests to identify the failing DIMM.

For more information about displaying POST results, see “How to Use POST Diagnostics” in the Sun Fire 880 Server Service Manual.

3.If POST displays the memory error as an MTAG error, then POST will not identify the failing DIMM correctly. In this case, see the Info Doc “Identifying MTAG

DIMM errors on the Sun Fire 880” on SunSolve Online web site.

PCI Hot-plug insert message is wrong for slots 7 and 8 (BugID 4546219)

On a Sun Fire 880 system running the Solaris 8 07/01 or 8 10/01 operating system, the message sent to the console during a hot-plug event on PCI slots 7 and 8 reverses the slots. If a card is inserted into slot 7, the system will reply to the console with a message containing the following text.

Device PCI8_CARD inserted

This bug effects only the display of the incorrect slot for the insert message. The drivers and other related hot-plug activity all occur on the correct PCI slot. When you continue with the hot-plug procedure by pressing the hot-plug button for the newly inserted PCI card in slot 7, the power-on message displays the correct slot number, with a message containing the following text.

card is powered on in the slot hpc0_slot7

Note For further information about this issue, see the SunSolve Online web site.

PCI attachment points should be generic (BugID 4388625)

The description of the attachment point ids (Ap_Id) for PCI cards in the Sun Fire 880 Dynamic Reconfiguration User’s Guide, shown in the following example, is incorrect for Sun Fire 880 systems running the Solaris 8 07/01 or 8 10/01 operating 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.
