5.Slide the power supply toward the centerplane.

Ensure that the extraction lever is in the outward position.

Ensure that the arrows in the quarter-turn access slots point to the unlocked position.

See Figure 7-8 and Figure 7-9. The power supply will not seat fully unless the lever is in this starting position.

Caution – DO NOT FORCE the power supply into a slot; this can cause

!damage to the power supply and system.

The power supply should insert and seat smoothly. If it binds, remove it, and inspect the slot for any obvious obstructions. Do not damage the springfingers at the bottom of the power supply.

6.Use the extraction lever to seat the power supply.

Swing the lever inward to the locked position. Do not press on the front panel of the power supply to seat it; doing so will damage the connector pins.

7.Mechanically lock the power supply to the system chassis by inserting a Phillips #1 screwdriver into each quarter-turn access slot and then turning to the locked position.

See Figure 7-7.

8.Check to be sure the green LED is lit.

If the green LED is not lit, the power supply is not seated properly. Repeat Step 4 to Step 8. If the green LED is still not lit, see Chapter 10, “Flow Diagrams for Troubleshooting” for more information.

You will see a message similar to the following example on your system console:

NOTICE: Core Power Supply 2 Installed

NOTICE: Core Power Supply 2 OK

NOTICE: Redundant power available

4000, 5000, 6000 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.
