Getting Started 7Looking things overIn any complex system, there is potential for a forgotten connection, aforgotten switch, or a loose connector. If you try to start up the server and itdoes not start up, perform the following checks:• Is the power cord connected to the CPU system and an AC outlet?• Is the AC outlet supplying power?• If a power strip is used, is it switched on? Is the circuit breaker set?• Does the voltage selection switch on the system’s power supplyreflect the proper voltage?Verifying your configurationIf your system is not operating correctly, the BIOS may contain an invalidconfiguration parameter. Enter the BIOS program and check yourconfiguration settings. The BIOS Setup utility, configuration fields, and theoptions for those fields are provided in the Maintaining and TroubleshootingGuide.Troubleshooting guidelinesAs you troubleshoot your system, keep the following guidelines in mind:• Never remove the system covers while the system is on.• Do not attempt to open the monitor. It is extremely dangerous.Even if the monitor power is disconnected, stored energy in themonitor’s components can cause a painful or harmful shock.• If a peripheral such as the keyboard, mouse, drive, or printer doesnot work, ensure that all connections are secure.• If the screen displays an error message, write it downword-for-word. You may be asked about it when calling TechnicalSupport.• Only qualified personnel should open the system for maintenance.• If you are qualified to maintain the system yourself, make certainyou are properly grounded before opening the system chassis.Important!If the CMOS has beencorrupted by a poweroutage or an interruptedflash update and you plugthe system into a poweroutlet, it will power upimmediately. This is normal.
