SP Switch2 service procedures

Note: Refer to ªHandling static-sensitive devicesº on page 4-1.

Note: If multiple cards are to be removed, label and record the position of each card and its associated I/O cable.

1.If the interposer card is a switch interposer, remove the I/O cable. v Only switch interposer cards have an attached I/O cable

2.Loosen the captive screw holding the card retention bracket to the switch chassis.

3.Swing the bracket out and remove it from the switch chassis.

4.Remove the interposer card from its slot by pulling outward on the hot-plug actuator handle.

Replacing an interposer card

Note: An interposer card may be either a:

vSwitch interposer

vBlank interposer

1.Position and hold the interposer card at the far end of the hot-plug actuator.

2.Insert the far end of the actuator into the actuator guides of the interposer slot.

3.Push the actuator to the end of the guide track.

4.Seat the interposer card into its switch planar jack by pushing the actuator handle inward.

5.Hook the card retention bracket to the chassis and swing the bracket closed. v Make certain all actuator handles are inside the bracket.

6.Secure the card retention bracket by tightening the captive screw.

7.If this was a switch interposer card, reconnect the I/O cable.

8.Return to the procedure that directed you here.

Removing the switch planar

Attention: Removal of the switch planar involves the removal of the switch's externally accessible plug-in assemblies. Do not attempt to remove the planar from the chassis.

Note: Refer to ªHandling static-sensitive devicesº on page 4-1.

1.Place the switch in service position.

v Refer to ªPlacing an SP Switch2 into service positionº on page 3-10.

2.Remove all fan assemblies.

v Refer to ªRemoving a fan assemblyº on page 4-2.

3.Remove all power supplies.

v Refer to ªRemoving a power supplyº on page 4-3.

4.Remove all installed interposer cards.

v Refer to ªRemoving an interposer cardº on page 4-6.

5.Remove the switch supervisor card.

v Refer to ªRemoving the switch supervisor cardº on page 4-5.

6.The switch planar in now considered to be removed.

Note: The new planar assembly is supplied as a chassis mounted unit.

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.
