When the enclosure does not start This section provides systematic instructions on what to try and where to go for help for the most common problems encountered during initial startup of the HP PC Blade Enclosure. If you are having specific blade PC trouble, see theWhen the Blade PC Does Not Start on page 57 section in this appendix. If the enclosure does not start: 1. Check the enclosure for the normal power up sequence: a. The front panel enclosure health LED and rear panel fan health, Integrated Administrator health, and power supply LEDs turn to solid green. b. The power supply fans and main fans start up. 2. Be sure that the enclosure is plugged into a working power outlet. 3. Be sure your power sources are working properly by checking the power LED on each power supply in the rear of the enclosure. For information about the location and function of all enclosure LEDs, see the LED and Switch appendix. 4. Be sure your power supplies are working properly by checking the fault LED on your power supplies in the back of the enclosure (see Table 7-2 Is the Power LED on Both Power Supplies Solid Green? on page 52or Table 7-3 Is the Fault LED on Both Power Supplies Off? on page 52). 5. Be sure that the enclosure has power by checking the enclosure power LED on the rear of the enclosure (see Table 7-2 Is the Power LED on Both Power Supplies Solid Green? on page 52or Table 7-3 Is the Fault LED on Both Power Supplies Off? on page 52) 6. Be sure the fans are functioning by checking the fan health LED on the rear panel of the enclosure (see Table 7-4 Is the Enclosure Power LED on the Rear Panel Green? on page 54 7. Be sure the center wall assembly is delivering power to your enclosure by checking if the enclosure health LED on the front of the enclosure is illuminated (see Table 7-1 Enclosure diagnostic steps on page 51). 8. If the Integrated Administrator is rebooting repeatedly, be sure that it is not rebooting due to a problem that initiates an Enclosure Self Recovery (ESR) reboot. Refer to the following sections in the HP PC Blade Enclosure Integrated Administrator User Guide on the Documentation CD that ships with your enclosure: ● "Enclosure Self Recovery" ● "System Short Circuit" for other continuous rebooting problems 9. Restart the enclosure by pressing the enclosure power button on the fan cage on the rear of the enclosure. CAUTION: Pressing the enclosure power button while the enclosure is running shuts down the enclosure and all blade PCs. 50 Chapter 7 Troubleshooting
