If the system-error LED is lit, remove the cover and check the diagnostic panel LEDs. The following table is a complete list of diagnostics panel LEDs followed by the FRU or action for correcting the problem. The information in the table is valid only when the system-error LED is lit. Notes: 1. If a diagnostics panel LED is lit and the information LED panel system-error LED is off, there is probably an LED problem. Run LED diagnostics. 2. To locate the LEDs on the system board, see "System-board LEDs" on page 42. 3. Check the System Error Log for additional information before replacing a FRU. 4. The DIMM error LEDs, microprocessor error LEDs, and VRM error LEDs turn off when the system is turned off. 82 xSeries 335 Type 8676, Type 8830: Hardware Maintenance Manual and Troubleshooting Guide
