4.With a wrist strap attached, gently pull the TOD/NVRAM chip from the clock board.

5.Align the TOD/NVRAM chip removed from the original clock board with the connector on the upgrade clock board so that pin 1 on the chip is aligned with pin 1 on the board.

A small crescent-shape indentation on both the chip and the connector denotes the top (mate these areas).

A small round indentation on the corner of the chip denotes pin 1.

6.Ensure that all pins on the TOD/NVRAM chip are aligned correctly with the board connector pins.

Caution To avoid system damage, make sure that you connect pin 1 on the TOD

!chip into pin 1 on the board connector.

7.Gently press on the top of the chip to seat it.

8.Carefully insert the board in the clock board slot component-side up, ensuring that the board does not slip out of the card guides.

9.Use the open extraction levers to seat the board. Push the board into the card cage, then simultaneously press both extraction levers to seat the board on the centerplane.

Do not press on the board front panel to seat it, doing so will damage the connector pins.

10.Secure the board to the chassis using the two captive screws, one on each side.

11.Connect any applicable interface cables to the front panel of the board.

This concludes the hardware portion of the clock board upgrade. Continue with the next section, “Updating the System Flash PROM” to complete the procedure.

Updating the System Flash PROM

After replacing the clock board, update the system flash PROM. If you have internet access, the patch can be downloaded using the following procedure. If you do not have internet access, obtain the PROM patch software from your local Sun service provider.

After the system flash PROM is reprogrammed, the flash utility attempts to reboot the system. If the system fails to auto reboot, power cycle or reset the system by pressing the reset button.

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.
