Procedures for switch assemblies

CAUTION:

The unit weight exceeds 18 Kg (40 lbs) and requires two service personnel to lift. (SPSFC002)

Attention: Components in the frame are susceptible to damage from static discharge. Always use an ESD wristband when working inside frame covers. (See ªPersonal ESD requirementsº on page 3-1 for more details.) Do not touch the pins or circuitry on these components.

Note

There are different levels of the switch assembly hardware. The following lists indicate serviceable FRUs for each level of switch assembly:

SPS Fans, circuit breaker, LED card, switch supervisor card, switch power card(s), fan assembly cable, supervisor/power cable, complete assembly.

SPS-8Fans, circuit breaker, LED card, switch supervisor card, switch power card(s), fan assembly cable, supervisor/power cable, complete assembly.

Removing the switch assembly

Perform these procedures to remove the switch assembly:

1.Ensure that the switch is offline (shutdown) from the control workstation and powered off from the control workstation.

Attention: Removing power from one switch assembly may affect other switch assemblies and processor nodes attached to it.

2.Turn the power switch on the switch assembly to Off (`0').

3.Detach all cables from rear of switch assembly noting where external frame cables are attached. If wrap plugs are installed, remove them and save for the new switch.

4.If this is a switch drawer (in multi-switch frame F/C 2030/1) and you are replacing the switch assembly, remove the two screws at the rear of the switch assembly.

5.Remove four screws from front of switch assembly and slide switch assembly out of the front of the frame.

6.Remove the front chassis and then remove the inner chassis from the outer chassis sleeve.

7.Return to the procedure that directed you here.

Replacing the switch assembly

Perform these procedures to replace the switch assembly:

1.Replace the inner chassis into the outer chassis sleeve and then replace the front chassis.

2.If wrap plugs are installed, they can be plugged on the new switch.

3.Slide switch through the front of the frame and reinstall four screws that hold the switch to the frame.

4.If this is a switch drawer (in F/C 2030/1) and you are reinstalling the switch assembly, reinstall the two screws at the rear of the switch assembly.

5.Reattach all cables to rear of switch assembly.

6.Turn the power switch on the switch assembly to On (`1').

7.Refer to ªRestoring a switch assembly to the active configurationº on page 3-8.

8.Return to the procedure that directed you here.

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.
