Hardware Problems Power Supply Use the information in Table 2-2 to troubleshoot power supply problems. Table 2-2: Power Supply Problems Problem Power is not working properly or power-related errors are occurring. Server does not boot. Possible Cause Power supplies are not connected properly. Power supplies are not working. System does not have enough power. Possible Solution Check for loose connections. Refer to "Loose Connections" in this chapter for more information. If the power supplies have LEDs, be sure that they indicate that each power supply is working properly. Refer to your server-specific user documentation for details on LEDs. If LEDs indicate a problem with a power supply, replace the power supply. Be sure that the system has enough power, especially if you recently added hardware. Additional power supplies may need to be added. Check the system information from the Integrated Management Log (IML) and use your server-specific user documentation for product-specific information. Refer to "Integrated Management Log" in Chapter 4. System Power Module Some servers use one or more System Power Modules (SPMs) to distribute direct current to system components. If your system uses SPMs, use Table 2-3 to troubleshoot SPM problems. 2-6 HP Servers Troubleshooting Guide
