General Description 2-15POSTPOST (Power On Self-Test) is the self-diagnostic program stored in the system memory.When you power on the server, the system automatically runs POST to check the mother board,ECC memory module, CPU module, keyboard, and mouse. POST also displays messages of theBIOS Setup utility, such as the start-up message, while in progress.With the factory setup of the server, the NEC logo appears on the display unit while POST is inprogress. (To display the POST check results, press Esc.)NOTE: You can set the POST check results to appear on the displayunit without pressing Esc. To do so, select "Enabled" for "Boot-timeDiagnostic Screen" under the Advanced menu of the BIOS setup utility.You don't always need to check the POST check results. Check messages that POST displays when: you use the NEC Express server for the first time. the server appears to fail. the server beeps for many times between power-on and OS start-up. an error message appears on the display unit.POST Execution FlowThe following describes the progress of POST in the chronological order.IMPORTANT: Do not make key entries or perform mouse operations while POSTis in progress. Some system configurations may display the message "Press AnyKey" to prompt a key entry. This message is driven by BIOS of aninstalled optional board. Make sure to read the manual that comeswith the optional board before any key entry. Powering on the server, after you installed or removed an optionalPCI board or moved it to another slot, may display the message thatindicates incorrect board configuration and suspend POST.In such a case, press F1 to continue POST. Board configuration canbe made using the utility described later.
