3.Under some circumstances, you may remove a power/cooling module from an active system for a short time. However, if the boards in the adjacent slots create large quantities of heat, it is safer to halt and power off the system first.

D.1.5 Filler Panels and Load Boards

1.All empty board slots must be filled with filler panels or load boards. For Enterprise 6000 systems, use load boards. (Requirement) A load board (part number 501-3142) is identified by the presence of connector sockets and passive circuitry, which reduces electrical noise at the center plane. Do not substitute filler panels, which do not have load circuits.

2.For Enterprise 5000 and 4000 systems, use filler panels (part number 540- 2592). (Requirement)

3.Filler panels are required for all unused PCM bays. (Requirement)

D.2 SBus Modules

1.Install double-wide SBus cards only on the SBus I/O board, at SBus slots 1 and 2. The location of SBus slot 0 prevents its use with double-wide cards.

2.Double-wide SBus cards cannot be used with the Graphics I/O board. The middle card connector does not fit SBus cards.

D.3 CPU Modules

1.Each CPU/Memory board has two sets of CPU connectors, marked “PROC 0” and “PROC 1”.

2.Do not mix CPU speeds—all CPUs run at the lowest common frequency.

3.To run 250 MHz CPU modules, the following are requirements:

a.The system must have clock board part number 501-4286.

b.The system must not have 250 MHz CPU modules with CPU modules of a different speed.

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.
