Removing the switch fans

Note: Refer to ªHandling static-sensitive devicesº on page 4-1 before removing or installing ESD sensitive devices.

Perform these procedures to remove a fan from an SP Switch assembly:

1.Perform ªPlacing a switch assembly into service positionº on page 3-9 to place the switch assembly into the service position.

2.Remove the top cover of the switch assembly by removing the screws.

3.Locate the fan.

4.Push shock mounts toward center of fan.

5.Pull fan out of the fan bracket. Keep the shock mounts for mounting the new fan.

6.Disconnect fan cable from supervisor control cable.

Replacing the switch fans

Perform these procedures to replace a fan in an SP Switch assembly:

1.Transfer shock mounts from the old fan to the new fan.

2.Using another fan as an example, route the fan cable and orient the fan with airflow indicator pointing toward the rear of the switch assembly.

3.Mount fan in the fan bracket by pulling the shock mounts through the holes in the fan bracket.

4.Push shock mounts outward to lock in place.

5.Reconnect fan cable to the supervisor control cable.

6.Reinstall top cover of switch assembly and reinstall all screws.

7.Perform ªReplacing a switch assembly from service positionº on page 3-9 to remove the switch assembly from the service position.

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.
