3.Remove the adapter from the system as documented in the system’s service manual.

Caution –You must follow the instructions outlined in your system’s service manual for the removal of network interface I/O cards. If you do not follow the procedures in the service manual, you may cause your system to panic.

In addition to the procedures documented in the server’s service manual, consider the following caution statements when removing faulty adapters, or when moving adapters to other slots, in hot-swap mode:

■If you are removing a rear-access version of the adapter, you must always remove the adapter’s front card before removing the rear transition card. If you remove the rear transition card first, you may panic the system.

■Do not trust the hot-swap LED on the adapter when removing the card from the system. On some systems, the hot-swap LED may turn on before the software has completely detached from the adapter. Use the LEDs on the system, as documented in the system’s service manual, when removing the adapter.

■If the server is set to full hot-swap mode, do not rapidly open and close the ejection levers. When you open the ejection levers, you will begin the software detachment process. This detachment process must end before you can safely close the ejection levers, which begins the software attachment process. If you open and close the levers rapidly, you can panic or hang the system.

■When moving more than one adapter to different slots in the system, move the adapters one at a time. If you move multiple adapters in rapid succession and at the same time, you may panic or hang the system.

6U specifications

Sun Microsystems, a prominent player in the computing industry, made significant contributions to the development of high-performance hardware and software solutions. One of the notable products from the company is the 6U form factor, which refers to a specific standard for rack-mounted equipment. The 6U standard is particularly relevant in the context of server architecture, storage solutions, and other critical systems used in enterprise environments.

The 6U form factor typically stands at 10.5 inches in height, accommodating various configurations of hardware components while ensuring a compact footprint. This size makes it ideal for data centers and server rooms, where space is often at a premium. Sun Microsystems effectively utilized this form factor in its server lineup, catering to performance and density requirements.

A defining feature of Sun Microsystems' 6U models is their modular architecture. These servers support a range of powerful processors, including the UltraSPARC series, renowned for their high processing capabilities and energy efficiency. The use of the UltraSPARC architecture allows for robust multitasking and parallel processing, making these systems suitable for demanding applications such as database management and enterprise resource planning.

Moreover, Sun Microsystems integrated advanced memory technologies within their 6U designs. The servers support large amounts of RAM, utilizing technologies like ECC (Error-Correcting Code) memory to enhance data integrity. This is crucial for mission-critical applications where data loss can result in substantial operational impact.

In terms of connectivity, the 6U form factor features a variety of interfaces, including high-speed Ethernet ports, Fibre Channel connections, and USB ports. These options enable seamless integration into existing network infrastructures, facilitating efficient data transfer and storage management.

Storage solutions within the 6U framework include support for multiple RAID configurations and high-capacity disk drives. Sun Microsystems provided options for both SSD and traditional HDD storage, allowing organizations to tailor their systems to meet specific performance and capacity needs.

In addition to hardware characteristics, Sun Microsystems placed a strong emphasis on software compatibility. Their systems were designed to run a variety of operating systems, including Solaris, Linux, and Windows, thereby providing flexibility for enterprises to deploy their preferred software environments.

Overall, the 6U form factor from Sun Microsystems symbolizes the company's commitment to delivering high-performance, reliable, and scalable computing solutions. By combining innovative technology with practical design, Sun Microsystems created servers that met the diverse needs of businesses and paved the way for advancements in enterprise computing.
