Light path diagnostic LED information for the IBM Flex System p260 Compute Nodev Follow the suggested actions in the order in which they are listed in the Action column until the problem issolved.v See Chapter 7, “Parts listing for IBM Flex System p260 and p460 Compute Nodes,” on page 97 to determinewhich components are CRUs and which components are FRUs.v If an action step is preceded by Trained service technician only, that step must be performed only by a trainedservice technician.Light pathdiagnostics LED islit Description ActionNone An error occurred and cannot be isolated, orthe service processor failed.An error occurred that is not represented by alight path diagnostics LED. Check the eventlog for information about the error.Battery errorP1-E1A battery error occurred.

Verify that the DIMM indicated by the litLED is a supported memory module, asdescribed on the ServerProven website.2. Replace the DIMM indicated by the litLED, as described in “Removing a DIMM”on page 55 and “Installing a DIMM” onpage 58.Note: Multiple DIMM LEDs do notnecessarily indicate multiple DIMM failures. Ifmore than one DIMM LED is lit, replace oneDIMM at a time until the error goes away.488 Power Systems: IBM Flex System p260 and p460 Compute Nodes Installation and Service Guide
