Symptom Action An IBM option that used to work v Make sure that all of the option hardware and cable connections are secure. does not work now. v If the option comes with test instructions, use those instructions to test the option. v If the failing option is a SAS device, make sure that: - The cables for all external SAS options are connected correctly. - The last device in each SAS chain, or the end of the SAS cable, is terminated correctly. - Any external SAS devices are turned on. You must turn on external SAS devices before turning on the server. If the problem remains, call for service. Power 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 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 The server does not turn on. v Make sure that the server power cord is connected to the server and a working electrical outlet. v Make sure that the type of memory that is installed is supported by the server and is installed in the correct order. v Make sure that the microprocessors are installed in the correct sockets. v If you just installed an option, remove it, and restart the server.
