Note – All empty card cage slots must contain a load board (Enterprise 6000 server) or filler panel (Enterprise 5000 or 4000 servers).

B.7 Network Interfaces

Each SBus I/O board and Graphics I/O board has onboard connectors for 10BASE-T or 100BASE-T Ethernet. The two sockets (RJ-45 and 40-pin MII) connect to the same interface circuit, so that only one socket is active at any time.

Additional network interfaces can be added in the form of SBus cards. The

SBus I/O board will support up to three SBus interface cards. The Graphics

I/O board will support up to two SBus interface cards.

B.8 Disk Board

The Disk board (with two SCSI disks) is an available option for the Enterprise systems. The Enterprise 6000 system supports two Disk boards (only in slots 14 and 15); the Enterprise 5000 and 4000 systems support four Disk boards.

The ID settings of the two disks on the Disk board vary according to the card cage slot location. See Appendix C, “SCSI Devices.”

B.9 Power Supplies

There are two types of power supplies in the Enterprise 6000, 5000, and 4000 systems. The power/cooling modules (PCMs) provide DC current and cooling air to boards in the card cage.

The peripheral power supply provides current for peripheral devices (such as a tape or CD-ROM drive) in the SCSI tray.

B.9.1 Power/Cooling Modules (PCMs)

The DC power to the centerplane is supplied by one or more PCMs. Each PCM also provides cooling air for two board slots. If a slot contains a board, the adjacent PCM slot must contain a PCM to supply cooling air.

Current from individual PCMs is shared on the centerplane.

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.
