Switch power (MAP 0610)

Step 0610-022

The switch's front panel power LED remained Off after replacing the LED power extension cable.

1.Replace the switch planar.

v Refer to ªRemoving the switch planarº on page 4-7 and ªReplacing the switch planarº on page 4-8

2.Is the front panel power LED On?

v If yes, go to Switch function (MAP 0620), ªStep 0620-021º on page 1-27 and return the switch to the active configuration.

v If no, call the next level of support.

Step 0610-023

The switch supervisor card was replaced and both the switch front panel and green switch supervisor LEDs remain Off.

1.Replace the switch's circuit breaker assembly.

2.Are both power LEDs On?

vIf yes, go to Switch function (MAP 0620), ªStep 0620-021º on page 1-27 and return the switch to the active configuration.

vIf no, go to ªStep 0610-024º.

Step 0610-024

The switch's circuit breaker assembly was replaced and both the switch front panel and green switch supervisor LEDs remain Off.

1.Replace the switch planar.

2.Are both power LEDs On?

v If yes, go to Switch function (MAP 0620), ªStep 0620-021º on page 1-27 and return the switch to the active configuration.

vIf no, call the next level of support.

Switch function (MAP 0620)

Purpose of this MAP

This MAP provides diagnostic information for problems related to the SP Switch2 function.

Notes:

1.Refer to ªAppendix Aº inRS/6000 SP: Installation and Relocation for frame-to-frame or switch-to-switch cables. Logical frame to physical frame translation information can also be found in this appendix.

2.Refer to ªService position proceduresº on page 3-10 for placing or removing the switch into or from service position.

Step 0620-001

A message in Perspectives indicated that you have a switch function problem and Table 1-1 on page 1-5directed you to this MAP.

1.To complete the following procedures, you will need to have primary node root access. (Customer may enter root password when required.)

2.If either of the following two conditions is true: v Estart has not been run by the customer

vThe CE has already replaced components that might affect the switch. Then from the control workstation, enter:

RS/6000 SP specifications

The IBM RS/6000 SP (Scalable Power) is a high-performance computing system that was developed in the early 1990s and has since become a significant player in the realm of supercomputing and enterprise solutions. Designed primarily for scientific, engineering, and complex data analysis tasks, the RS/6000 SP provides powerful processing capabilities, enhanced scalability, and features to support demanding applications.

One of the key characteristics of the RS/6000 SP is its modular architecture, which allows for the addition of multiple nodes. Each node is based on IBM's Power architecture, leveraging the RISC (Reduced Instruction Set Computing) design to achieve high throughput and efficiency. The system can support configurations ranging from a few nodes to hundreds, enabling organizations to scale their computational power as needed based on workload requirements.

The RS/6000 SP employs advanced interconnect technologies, most notably the SP Switch, which ensures high-speed communication between nodes. This interconnect allows for seamless data transfer, ensuring that the system can handle large datasets and complex computations without bottlenecks. The SP's ability to deliver concurrent processing capabilities makes it ideal for parallel computing tasks, including simulations, modeling, and large-scale computations.

In terms of software, the RS/6000 SP was equipped with AIX, IBM's version of the UNIX operating system, which provides a stable and secure environment for enterprise applications. Furthermore, the system supports a vast array of programming languages and tools, including Fortran, C, and C++, along with libraries and frameworks designed for high-performance computing. This compatibility allows developers to optimize their applications to fully utilize the underlying hardware.

Another notable feature of the RS/6000 SP is its extensive support for various workloads, including database management, multi-user applications, and graphical processing. The system was equipped with high-performance graphics capabilities, making it suitable for tasks that require intensive visualization, such as computer-aided design (CAD) and scientific visualization.

Overall, the IBM RS/6000 SP has solidified its role in the high-performance computing landscape, combining advanced technologies, robust scalability, and flexibility to meet the unique demands of research and enterprise environments. Its legacy continues to influence modern computing architectures, embodying IBM’s commitment to innovation and performance in the pursuit of complex problem-solving capabilities.
