v Check the power supplies, see Power-supply LEDs. v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See Chapter 3, "Parts listing, Type 8864," on page 23 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. Lit light path diagnostics LED with the system-error or system-information LED also lit Description Action DASD A hard disk drive has failed or has been removed. Note: The error LED on the failing hard disk drive is also lit. 1. Reinstall the removed drive. 2. Reseat the following components: a. Failing hard disk drive b. SAS hard disk drive backplane c. SAS 6x cable d. I/O board 3. Replace the components listed in step 2 one at a time, in the order shown, restarting the server each time. RAID The RAID adapter (ServeRAID 8i) has indicated a fault. 1. See the BMC log or the system-error log (see "Error logs" on page 70). 2. Reseat the following components: a. RAID adapter b. Hard disk drives c. I/O board 3. Replace the components listed in step 2 one at a time, in the order shown, restarting the server each time. NONRED The server is operating with nonredundant power. If a power supply or its ac power source fails, the system will be over spec. Note: The LOG LED might also be lit. 1. If the PS LED on the light path diagnostics panel is lit, follow the instructions for that LED. 2. Replace the failing power supply. 3. Remove optional devices. 4. Use 220 VAC instead of 110 VAC. TEMP A system temperature or component 1. See the BMC log or the system-error log (see has exceeded specifications. "Error logs" on page 70) for the source of the fault. Note: A fan LED might also be lit. 2. Make sure that the airflow of the server is not blocked. 3. If a fan LED is lit, reseat the fan. 4. Replace the fan for which the LED is lit. 5. Make sure that the room is neither too hot nor too cold (see "Environment" in "Features and specifications" on page 3). 6. If one of the VRDs indicates "hot," ac power must be removed before dc power can be restored. Chapter 5. Diagnostics 107
