Switch power (MAP 0610)

Step 0610-009

The switch circuit breaker no longer trips to the Off (`0') position when a fan/power supply pair is removed.

1.Reinstall the power supply into the switch.

2.Check circuit breaker.

3.Does the circuit breaker still trip?

vIf yes, go to ªStep 0610-010º.

vIf no, go to ªStep 0610-011º.

Step 0610-010

A power supply caused the circuit breaker to trip.

1.Replace the power supply.

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

Step 0610-011

The circuit breaker does not trip with the fan removed.

1.Replace the fan.

2.Return to ªStep 0610-004º on page 1-14 to verify the replacement fan.

Step 0610-012

You removed a fan/power supply pair and the circuit breaker still trips.

1.Reinstall the fan/power supply pair.

v If you have tested all fan/power supply pairs, go to ªStep 0610-013º.

2.Remove the next fan/power supply pair.

3.Return to ªStep 0610-005º on page 1-14 and test the next fan/power supply pair.

Step 0610-013

You tested (by removal and replacement) all fan/power supply pairs and the circuit breaker still trips.

1.Remove the switch supervisor card.

2.Check the circuit breaker.

3.Does the circuit breaker still trip?

v If yes, reinstall the switch supervisor card and go to ªStep 0610-014º.

vIf no, replace the switch supervisor card and return to ªStep 0610-004º on page 1-14 to verify fix.

Step 0610-014

You removed the switch supervisor card but the circuit breaker still trips.

1.Remove all interposer cards to isolate.

2.Check the circuit breaker.

3.Does the circuit breaker trip?

v If yes, go to ªStep 0610-017º on page 1-16.

vIf no, go to ªStep 0610-015º.

Step 0610-015

1.Reinstall the interposer cards one at a time.

2.Does the circuit breaker trip?

v If yes, replace the interposer and return to beginning of this step to test the replacement interposer.

vIf no, go to ªStep 0610-016º.

Step 0610-016

1.Reinstall the next interposer card.

2.Return to ªStep 0610-015ºand check that the circuit breaker does not trip.

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.
