SP Switch environment (MAP 0600)

3.Is the measured resistance now within the acceptable range? v If yes, go to ªStep 0600-017º on page 1-10 to verify fix.

vIf no, go to ªStep 0600-008º.

Step 0600-008

You replaced the inner chassis cable and the front chassis cable but the measured resistance is still outside of the acceptable range.

1.This indicates that there is still a problem.

2.Replace the switch supervisor card.

3.Go to ªStep 0600-017º on page 1-10 to verify fix.

Step 0600-009

You have voltage shutdown condition, the supervisor control cable appears to be okay, and the resistance value you measured in Table 1-3 on page 1-6was within an acceptable range. Based on these symptoms, ªStep 0600-005º on page 1-6 directed you to this location.

1.Reconnect cable S00-PC-P4 at switch power supply 1.

2.Repeat resistance measurement from ªStep 0600-005º on page 1-6.

3.Is the measured resistance within the acceptable range?

v If yes, replace switch power supply 1 and the switch supervisor card.

a. Go to ªStep 0600-017º on page 1-10 to verify fix. v If no, go to ªStep 0600-010º.

Step 0600-010

With cable S00-PC-P4 reconnected at the switch power supply 1, the measured resistance values were still outside the acceptable range.

1.Reconnect cable S00-PC-P6 at switch power supply 2.

2.Repeat resistance measurement from ªStep 0600-005º on page 1-6.

3.Is the measured resistance within the acceptable range? v If yes, replace switch power supply 2.

a. Go to ªStep 0600-017º on page 1-10 to verify fix.

vIf no, the problem is in the switch supervisor card. a. Go to ªStep 0600-011º, Priority 3.

Step 0600-011

You arrived at this step because you received a ª...fanfail...º message or you found a problem with the switch supervisor control cable (S00-SP-P102).

1.One or more of the following conditions exist:

v Warning Fan: ªfanwarning1º, ªfanwarning2º, ..., ªfanwarning5º

v Shutdown Fan: ªfanfail1º, ªfanfail2º, ..., ªfanfail5º

2.Have customer remove the SP Switch from the active configuration and power off the SP Switch.

3.Set switch circuit breaker to the Off position.

4.Unplug cables connected to J1 and J2 at the rear of the SP Switch.

5.Remove the front panel assembly from the inner chassis.

6.Use Table 1-4 on page 1-8to reseat or replace components:

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.
