FRU/CRU isolation Error codes and the recommended actions for each code are provided in Chapter 10, "Symptom-to-FRU index," on page 93. These actions can provide you with informational messages and directions or can refer you to Chapter 11, "Parts listing, Type 8842," on page 159. If a replacement part is indicated, the part is referred to by name. The physical location codes are listed for each occurrence as required (see "Physical location codes" on page 154). Chapter 11, "Parts listing, Type 8842," on page 159 provides a parts index with the predominant field replaceable units (FRUs) or customer replaceable units (CRUs) listed by name, and provides illustrations of the various assemblies and components that make up the blade server. Error symptom charts You can use the error symptom charts to find solutions to problems that have definite symptoms (see "Error symptoms" on page 145). If you cannot find the problem in the error symptom charts, go to "Checkout procedure" on page 38 and "Undetermined problems" on page 156. If you encounter problems with an Ethernet or Fibre Channel switch module, IBM BladeCenter Optical Pass-Thru Module, I/O expansion card, or other Eserver optional device that can be installed in the BladeCenter unit, see the applicable Hardware Maintenance Manual and Troubleshooting Guide on the IBM BladeCenter Documentation CD or other documentation that comes with the device for more information. Light path diagnostics Many errors are first indicated when the blade-error LED on the blade server is lit (see "Blade server controls and LEDs" on page 14). If this LED is lit, one or more error LEDs elsewhere in the blade server might also be lit and can direct you to the source of the error. This section describes how to use the light path diagnostics to identify problems that might arise. To locate the actual component that caused the error, you must locate the lit error LED for that component. Note: Read Appendix B, "Safety information," on page 163 and "Handling static-sensitive devices" on page 71. For example, if a blade error has occurred and the blade-error LED is lit on the blade server, complete the following steps: 1. Turn off the blade server and remove it from the BladeCenter unit. 2. Place the blade server on a flat, static-protective surface. 3. Remove the cover from the blade server (see "Opening the blade server cover" on page 74). 46 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
