SP Switch power (MAP 0610)

Step 0610-001

A message in Perspectives indicated that you have a power problem and Table 1-1 on page 1-4or Table 1-2 on page 1-5directed you to this MAP.

1.From a Perspectives window on the control workstation or by looking at the SP Switch, check the Power (green) LED for this SP Switch.

2.The definition of the Power (green) LED is as follows:

Power (Green)

Off No 48 V dc power available at the SP Switch.

Flashing

Power available at the SP Switch, but switch logic is Off.

On Power available at the SP Switch, and logic is On.

3.Is Power (green) LED Off?

v If yes, go to ªStep 0610-004º.

vIf no, go to ªStep 0610-002º.

Step 0610-002

You found the switch Power (green) LED was lit. This indicates that the SP Switch is getting 48 V dc power.

1. Is Power (green) LED flashing?

vIf yes, go to ªStep 0610-003º.

vIf the Power LED is lit and it is not flashing:

a.This indicates that you do not have a power supply problem.

b.Verify that you have the proper SP Switch, then restart ªSP Switch description and problem determination (MAP 0590)º on page 1-1.

c.If this is the proper SP Switch, call the next level of support.

Step 0610-003

The Power LED is lit and it is flashing.

1.This indicates that the SP Switch is getting power.

2.Power up switch logic from the virtual front panel on the control workstation.

3.Does Power (green) LED light and stay lit? v If yes, the switch logic is getting power.

a.Go to ªSP Switch function (MAP 0620)º on page 1-17 and refer to ªStep 0620-043ºon page 1-36.

v If the Power LED does not stay lit, the SP Switch is not responding to the command.

a.Go to ″Frame supervisor not responding (MAP 0110)″ in RS/6000 SP: System Service Guide.

Step 0610-004

From either a Perspectives window or by looking at the SP Switch, you determined that the Power (green) LED is Off.

1.Check the SP Switch's circuit breaker.

2.Put this circuit breaker in the On (`1') position if it is not already in that position.

3.Does the circuit breaker go (trip) to the Off (`0') position?

vIf yes, go to ªStep 0610-005º on page 1-15.

vIf no, go to ªStep 0610-006º on page 1-15.

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.
