250 IBM eX5 Implementation GuideThis precaution will eliminate the possibility of a single breaker or circuit fault from takingdown the entire server.Think of the power supplies in your server as shock absorbers in your car. They are designedto absorb and overcome a wide variety of power conditions that can occur from an electricutility company, but like shock absorbers on a car, they will eventually begin to fail when fed asteady diet of unstable power. The time of their failure will most likely not coincide with aplanned maintenance panel. For this reason, ensure that the two halves of the power suppliesare plugged into two separate UPS sources to filter out all of the moderate to severe powerfluctuations that occur.6.8 Using the Integrated Management ModuleFor any successful server implementation, there must be provisions set aside to provideaccess to perform troubleshooting or routine maintenance. The x3850 X5 ships standard withthe Integrated Management Module (IMM). The IMM is a separate, independent operatingenvironment that starts to activate and remains active while the server is plugged into a goodac power source. The IMM monitors the hardware components of the server and theenvironment on which the server operates, looking for a potential hardware fault.Part of the information that is stored in the IMM can be accessed with F1-Setup by selectingSystem Settings Integrated Management Module. Figure 6-26 show the first panel ofthe IMM configuration panel.Figure 6-26 Integrated Management Module configuration panelTip: If you have a server but you do not know the logon credentials, you can reset it bygoing to the panel that is shown in Figure 6-26, from F1-Setup, and then restore the IMMconfiguration to the factory defaults by selecting Reset IMM to Defaults.
