Switch power (MAP 0610)

3. If all interposers have been tested, go to ªStep 0610-004º on page 1-14.

Step 0610-017

You tested all interposers and the circuit breaker still trips.

1.Replace the circuit breaker assembly.

2.Check the circuit breaker.

3.Does the circuit breaker still trip? v If yes, go to ªStep 0610-018º.

vIf no, return to ªStep 0610-004º on page 1-14 to verify fix.

Step 0610-018

You replaced the circuit breaker assembly but the circuit breaker still trips.

1.Replace the switch planar.

2.Return to ªStep 0610-004º on page 1-14 to verify fix.

Note: If replacing the switch planar does not correct this problem (verify fix fails), call the next level of support.

Step 0610-019

The switch circuit breaker is in the On position, the input power cable connections appear good, and the green switch supervisor LED is Off.

1.Replace the switch supervisor card.

2.Are both the green switch supervisor and front panel 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:

±If both the green switch supervisor and front panel power LEDs are Off, go to ªStep 0610-023º on page 1-17.

±If the front panel power LED is Off but the green switch supervisor LED is On, go to ªStep 0610-020º.

Step 0610-020

The front panel power LED is Off, but the green switch supervisor LED is On.

1.Replace the switch's LED bracket assembly.

2.Is the front panel power LED 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:

a.Call the next level of support.

±You may be advised to replace the LED power extension cable and, if needed, the switch planar.

b.If advised to proceed, go to ªStep 0610-021º.

Step 0610-021

The switch's front panel power LED remained Off after you replaced the LED bracket assembly and you were advised to continue troubleshooting.

1.Replace the LED power extension cable.

2.Is the front panel power LED 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 0610-022º on page 1-17.

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.
