3.3.4 Powering Off the System

Before turning off the system power, you must halt the operating system. See the Preface, “UNIX Commands,” to find references if you need help with the commands for this task or other system administration procedures.

Note – Failure to halt the operating system properly can cause the loss of disk drive data.

Note – Do not disconnect the terminal while the system is running.

Caution – To avoid damaging internal circuits, do not disconnect or plug in any cable while power is applied to the system.

To shut down the system:

1.Notify users that the system is going down.

2.Back up the system files and data to tape, if necessary.

3.Halt the system using the appropriate commands. Refer to the Solaris Handbook for SMCC Peripherals that corresponds to your operating system.

4.Wait for the system-halted message and the boot monitor prompt.

5.Turn the key switch on the front panel of the server to the Standby position (fully counterclockwise).

6.Turn off the system power in this order:

a.External drives and expansion cabinets (if any)

b.System AC power switch

c.Terminal

For more system administration information on methods for shut-down and backup, see the Preface, “UNIX Commands,” for references to documentation that describes these procedures.

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.
