▼To Power On the Server

This procedure describes a general overview for powering on the server. Refer to your server’s documentation for the exact procedure.

1.Before powering on the server, make sure that all any peripheral devices connected to the server are powered on.

2.Follow the appropriate procedures, as documented in the server’s service manual, to power on the system.

Refer to the server’s documentation for the complete power on procedure.

For example, if you installed the adapter in a Netra ct server, refer to the Netra ct Server Service Manual. This manual contains the power on procedures.

3.During the power on sequence, watch the hot-swap LED on the adapter’s front card (FIGURE 2-11).

■The LED should blink quickly and then stay off if the adapter was installed correctly.

■If the hot-swap LED remains on (lit), the adapter was not installed correctly. One or both of the cards may not be seated correctly in the slot. You must remove and reinstall the adapter’s two cards to make sure that they sit correctly in the slots. Use the cold-swap procedures to re-install the two cards:

■Power off the server

■Remove and replace the rear transition card

■Remove and replace the front card

■Power on the server

Refer to the system’s documentation for additional troubleshooting instructions.

4.Verify that the server’s power LED is on (lit), indicating that the system has completely powered on.

Refer to the server’s documentation for the location of the power LED. For example, on a Netra ct server, the power LED is on the front panel.

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.
