Table 5-1 Diagnostic LED codes (continued) Chassis indicator LEDs Power LED and sound activity Diagnosis and service action Blinks red 2 times (once per second), then a 2-second pause, and then 2 beeps Thermal shutdown has occurred. Perform the following: 1. Ensure that the workstation air vents are not blocked. 2. Open the access panel and press the workstation power button. 3. Verify that the system fan is running. 4. Verify that the processor heatsink fan spins. If it does not spin, ensure that the fan cable is plugged into the system board connector. Ensure that the heatsink is properly seated. 5. Replace the processor heatsink. Blinks red 3 times (once per second), then a 2-second pause, and then 3 beeps Processor is not installed. Perform the following: 1. Install the processor. 2. Reseat the processor. 3. If the problem persists, replace the processor. Blinks red 4 times (once per second), then a 2-second pause, and then 4 beeps Power failure. Perform the following: 1. Perform the power supply self-test. 2. Open the access panel and verify that the necessary power supply cables are connected to the system board. 3. Locate a faulty device by removing all devices, and then reinstalling them one at a time until the workstation fails: a. Disconnect AC power to the workstation. b. Remove all devices. c. Reinstall a device d. Reconnect AC power. 4. Replace the device causing the failure. 5. Continue adding devices to ensure all are functioning properly. 6. Verify power supply functionality. Perform the following: a. Disconnect AC power. b. Remove all internal power supply cables from the system board. c. Plug in AC power. ● If the power supply fan spins and the LED illuminates (see Testing power supply on page 118), the power supply is good. Replace the system board. ● If the power supply fan does not spin or the LED does not illuminate (see Testing power supply on page 118), replace the power supply. Blinks red 5 times (once per second), then a 2-second pause, and then 5 beeps Pre-video memory error 1. Ensure that the memory modules are loaded correctly (Required system board DIMM installation order on page 75). 2. Reseat memory modules. 3. Replace memory modules one at a time to find the faulty module. ENWW Customer Self Help 115
