SP Switch environment (MAP 0600)

2.Remove the switch supervisor card (refer to ªRemoving the switch supervisor cardº on page 4-4).

3.Using a digital multimeter, measure resistance at the planar connection for the supervisor card, between pins 12A and 12B.

v The resistance should be in a range of 4 to 20 ohms.

4.Is the measured resistance in the acceptable range? v If yes:

a.Replace supervisor card as described in ªReplacing the switch supervisor cardº on page 4-5.

b.Go to ªStep 0600-017º on page 1-10.

vIf no, go to ªStep 0600-021º.

Step 0600-021

With connectors S00-PC-P4, S00-PC-P6 disconnected, the measured resistance between pins 12A and 12B is outside the specified range.

1.Remove power supply card PS1 (refer to ªRemoving the switch power cardsº on page 4-6.

2.Repeat the resistance measurement from ªStep 0600-020º on page 1-10.

3.Is the measured resistance in the acceptable range? v If yes:

a.Replace the power supply card (refer to ªReplacing the switch power cardsº on page 4-7.

b.Go to ªStep 0600-017º on page 1-10.

vIf no, go to ªStep 0600-022º.

Step 0600-022

Connectors S00-PC-P4 and S00-PC-P6 are disconnected and you removed power supply card PS1 but the measured resistance between pins 12A and 12B is still outside the specified range.

1.If this is the first time through this step:

a.Remove power supply card PS2

b.Go to ªStep 0600-020º on page 1-10 and repeat the resistance measurement

2.If you have already been through this step:

a.Replace the switch assembly. Go to ªStep 0600-017º on page 1-10.

Step 0600-023

You arrived at this location from ªStep 0600-018º on page 1-10 where you found a condition state reporting a PSxFail or PSxFuseGood problem.

1.If you have a PSFuseGood problem, go to ªStep 0600-027º on page 1-12.

2.If you have a PS1Fail problem, go to ªStep 0600-025º on page 1-12.

3.If you have a PS2Fail problem, go to ªStep 0600-024º.

Step 0600-024

You have a PS2Fail problem.

1.Replace power supply card PS2.

2.Reinstall the SPS front panel assembly, being careful to align the guide pins on the P1 to the inner chassis cup guide.

3.Replug the power cable (J1) and supervisor cable (J2) to the rear of the assembly.

4.Put the circuit breaker in the On (`1') position.

5.Does the PS2Fail condition still exist?

v If yes, go to ªStep 0600-026º on page 1-12.

v If no, go to ªStep 0600-017º on page 1-10.

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.
