Software problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide on the IBM System x Documentation CD to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action You suspect a software problem. 1. To determine whether the problem is caused by the software, make sure that: v The server has the minimum memory that is needed to use the software. For memory requirements, see the information that comes with the software. If you have just installed an adapter or memory, the server might have a memory-address conflict. v The software is designed to operate on the server. v Other software works on the server. v The software works on another server. 2. If you received any error messages when using the software, see the information that comes with the software for a description of the messages and suggested solutions to the problem. 3. Contact your place of purchase of the software. Universal Serial Bus (USB) port problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide on the IBM System x Documentation CD to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action A USB device does not work. 1. Make sure that: v The correct USB device driver is installed. v The operating system supports USB devices. 2. Make sure that the USB configuration options are set correctly in the Configuration/Setup Utility program (see the User's Guide on the IBM Documentation CD for more information). 3. If you are using an external USB hub, disconnect the USB device from the hub and connect it directly to the server. Video problems See "Monitor problems" on page 61. Light path diagnostics Light path diagnostics is a system of LEDs on various external and internal components of the server. When an error occurs, LEDs are lit throughout the server. By viewing the LEDs in a particular order, you can often identify the source of the error. 68 IBM System x3550 Type 7978: Installation Guide
