SP Switch environment (MAP 0600)

6.Check the Environmental (yellow) LED for an ON or FLASHING condition.

7.Is the Environmental (yellow) LED ON or FLASHING? v If the Environmental LED is on or flashing:

a.Put the SP Switch's circuit breaker into the Off (`0') position.

b.Return to ªStep 0600-011º on page 1-7 and continue service with the next highest priority.

vIf the Environmental LED is not on or flashing:

a.You have resolved the problem.

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

Step 0600-013

Perspectives indicated a shutdown temperature condition and Table 1-2 on page 1-5directed you to this step.

Temperature is out of specified range; however, no serious electrical current or fan speed problems have been detected.

1.Check for airflow blockage at air intakes and exhaust of the SP Switch and system frame. Also, check air temperatures around the frame, looking for sources of abnormally high temperatures (above 40C or 104F).

2.Is there an obvious airflow blockage or abnormally high temperature source near air intakes? v If yes, go to ªStep 0600-016º.

vIf no, go to ªStep 0600-014º.

Step 0600-014

You have an over temperature condition but you did not find an obvious airflow blockage or abnormally high temperature source near air intakes. This indicates that there is a problem in the switch supervisor card.

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

2.Set the circuit breaker to the Off position. Unplug cables connected to J1 and J2 at rear of the SP Switch.

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

4.Replace the switch supervisor card.

5.Perform ªSwitch supervisor self-testº on page 3-4.

6.Does the card pass self-test?

v If yes, go to ªStep 0600-015º.

vIf the card does not pass self-test, check the cable connections to the switch supervisor card. If no obvious problems are found, call next level of support.

Step 0600-015

The switch supervisor card passed the self-test.

1.Check Environmental (yellow) LED for ON or FLASHING condition.

2.Is the Environmental (yellow) LED ON or FLASHING?

vIf the Environmental LED is on or flashing, check the cable connections to the switch supervisor card. If no obvious problems are found, call next level of support.

vIf the Environmental LED is not on or flashing:

a.You have resolved the problem.

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

Step 0600-016

You found an obvious airflow blockage or abnormally high temperature source near air intakes.

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

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.
