Using the OpenBoot PROM FCode Self- Test

The following tests are available to help identify problems with the adapter if the system does not boot.

You can invoke the FCode self-test diagnostics by using the OpenBoot PROM (OBP) test or test-allcommands. If you encounter an error while performing diagnostics, appropriate messages will be displayed. Refer to the OpenBoot Command Reference Manual for more information on the test and test-allcommands.

The FCode self-test exercises most functionality subsection by subsection and ensures the following:

■Connectivity during adapter board installation

■Verification that all components required for a system boot are functional

▼Performing the Ethernet FCode Self-Test Diagnostic

To perform the Ethernet diagnostics, you must first bring the system to a stop at the OBP prompt after issuing a reset. If you do not reset the system, the diagnostic tests might cause the system to hang.

For more information about the OpenBoot commands in this section, refer to the OpenBoot Command Reference Manual.

1.Shut down the system.

Use the standard shutdown procedures described in the Solaris Handbook for Sun Peripherals.

2.At the OBP prompt, set the auto-boot?configuration variable to false.

ok setenv auto-boot? false

4000 specifications

Sun Microsystems, a pivotal player in the computing industry during the late 20th and early 21st centuries, was renowned for its innovative hardware and software solutions. Among its notable offerings were the Sun-6000, Sun-5000, and Sun-4000 series, powerful workstations and servers designed for a range of enterprise-level applications.

The Sun-6000 series, introduced in the early 1990s, marked a significant advancement in computing performance. These systems were built on the SPARC architecture, which facilitated high levels of processing power and multitasking capabilities. One of the main features of the 6000 series was its scalability, allowing organizations to increase their processing power by adding more modules. It also offered robust graphics performance, making it ideal for scientific visualization and complex data analysis.

Next in line was the Sun-5000 series. Launched shortly after the 6000 series, the 5000 line was celebrated for its reliability and ease of management. This series emphasized a balanced architecture, which combined processing capabilities with ample memory and storage options. Key characteristics included support for multiple processors, leading to improved performance for demanding applications. Additionally, the 5000 systems featured advanced input/output capabilities, ensuring fast data transfers—crucial for database applications and web servers.

Finally, the Sun-4000 series targeted businesses seeking affordable yet potent computing solutions. These servers boasted a modular design, allowing for easy upgrades and maintenance. The 4000 series was particularly notable for its support for various operating systems, including SunOS and Solaris. These systems were engineered to handle a range of workloads, from enterprise resource planning to web hosting, while still fitting into a value-driven budget.

Across all three series, Sun Microsystems prioritized compatibility and integration, ensuring that each system offered seamless connectivity with Sun's software solutions and third-party applications. Their commitment to open standards and interoperability set them apart in the competitive landscape of enterprise computing. Additionally, the use of high-quality components lent the systems durability, making them a wise investment for organizations looking to future-proof their IT infrastructure.

In summary, the Sun-6000, 5000, and 4000 series exemplified Sun Microsystems' ethos of innovation and reliability. These powerful systems catered to diverse business needs, setting benchmarks in performance and functionality that continue to influence modern computing.
