12.3 Restarting the System

Note – As the system starts up, watch for error messages from the POST diagnostic program. If a terminal is not already part of the system, install a TTY terminal before continuing the startup. See Section 9.1, “Using a Terminal,” on page 9-1 for terminal settings.

1.The system key switch must be turned to(the standby position). See Figure 12-1 or Figure 12-3.

Caution – The outlet must be a 120-240 VAC 30-ampere circuit, intended solely

!for use by the server cabinet, as described in the site preparation instructions in the Ultra Enterprise 6000/5000/4000 Systems Installation Guide. The electrical receptacle must be grounded, and the grounding conductor serving this receptacle must be connected to the earth ground at the service equipment.

2.Enterprise 6000/5000 systems only: turn the Local/Remote switch down, to

Local.

See Figure 12-6.

3.Turn on the AC power sequencer power switch. See Figure 12-2 or Figure 12-4.

4.Turn on power to the terminal.

A terminal is required for viewing system messages. For setup instructions, see Section 9.1, “Using a Terminal,” on page 9-1.

5. Turn the key switch to

(the power on position).

See Figure 12-1 or Figure 12-3.

Several things will happen:

•The left front panel LED (green) turns on immediately to indicate the DC power supply is functioning.

•The middle front panel LED (yellow) lights immediately and should turn off after approximately 60 seconds.

•The right front panel LED (green) flashes after POST has ended to show that booting is successful and the operating system is running.

•The terminal screen lights up upon completion of the internal self test.

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.
