Appendix B. Problem solving

Computer problems can be caused by hardware, software, or user error. Using the information in this section, you might be able to solve problems yourself or gather helpful information that you can pass on to a service technician. You might also need to refer to your computer, operating-system, or sound-adapter documentation.

Review the following list for any problem description that might fit your situation.

vYour computer or CD-RW/DVD-ROM Combination Drive does not operate correctly, or the busy indicator light does not come on.

Take the following actions:

1.Check that the disc is loaded with the label side up.

2.Check that all devices are properly connected to the computer and to the electrical outlet.

3.Turn off the computer, unplug the cables for your computer and all attached devices, and remove the computer cover.

4.Check that all power and IDE cables are securely attached. Disconnect the IDE cable and check for bent or misaligned pins. If you do not find any problems, reconnect the interface cable. Replace the computer cover, and reattach all cables and power cords. Turn on the computer, restart the operating system, and attempt to open the loading tray by pressing the Open/Close button. If the tray fails to open and the Busy indicator does not light, turn off the computer and try using another 4-pin dc power cable.

5.Check that the color-coded edge on the IDE cable aligns with pin 1 on the IDE connector and is closest to the power cable on the CD-RW/DVD-ROM Combination Drive. See “Step 6. Attaching the cables to the drive” on page 1-7.

6.Check the CD-RW/DVD-ROM Combination Drive and any other device on the IDE cable for the proper settings.

7.If the middle connector on the IDE cable is attached to the IDE connector on the system board, remove the connector and reattach the cable. If there is only one device on the IDE connector, attach the connector at one end of the cable to the IDE connector and the connector at the other end to the device, leaving the middle connector (if there is one) open.

If there are two devices on the IDE connector, attach the connector at one end of the cable to the IDE connector. If there is a hard disk drive, attach it to the connector at the other end of the cable, and attach the CD-RW/DVD-ROM Combination Drive to the middle connector.

22P6975 specifications

The IBM 22P6975 is a crucial component within the IBM information technology ecosystem, specifically designed to enhance the capabilities of IBM servers. It is a high-performance memory module that plays a significant role in improving overall system efficiency, reliability, and speed. Particularly, it is built to fit into IBM System x and BladeCenter systems, making it a versatile option for various configurations.

One of the standout features of the IBM 22P6975 is its DDR3 SDRAM technology. DDR3 memory is known for its data transfer rates and reduced power consumption compared to its predecessors. The 22P6975 operates at a speed of 1333 MHz, although it can also support speeds up to 1600 MHz, providing an efficient solution for demanding server applications. Its architecture supports improved bandwidth and lower latency, which are vital for performance-intensive tasks.

In terms of capacity, the IBM 22P6975 typically comes with a size of 4GB, allowing for ample memory space for running multiple applications and services simultaneously. The module is designed with a 240-pin DIMM form factor, making it easily installable in compatible server systems. The Registered ECC (Error-Correcting Code) feature is another significant advantage, as it enhances data integrity by detecting and correcting internal data corruption, thus ensuring maximum uptime and reliability for critical applications.

The memory module is also designed with thermal management in mind. It operates efficiently within a wide range of temperatures, making it suitable for enterprise environments where reliability is paramount. The IBM 22P6975 adheres to stringent industry standards and provides backward compatibility with earlier memory technologies, ensuring businesses can upgrade their systems without having to overhaul existing infrastructure.

Furthermore, the 22P6975 is part of IBM's commitment to sustainability, as it operates at lower power levels, which reduces energy consumption and operational costs. This feature not only benefits the environment but also contributes to the overall cost-effectiveness of maintaining a data center.

In summary, the IBM 22P6975 memory module is characterized by its advanced DDR3 technology, substantial memory capacity, ECC capabilities, and energy-efficient operation. It is an integral part of IBM's server solutions, delivering reliability and performance for businesses that require robust IT infrastructure. This module is a valuable investment for any organization looking to enhance their computing capabilities while ensuring data integrity and system reliability.
