Installing a fixed power supplyThe following notes describe the type of power supply that the server supportsand other information that you must consider when you install a power supply:v To confirm that the server supports the power supply that you are installing, seehttp://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Before replacing a power supply with one of a different wattage, the user mayuse the IBM Power Configurator utility to determine current system powerconsumption. For more information and to download the utility, go tohttp://www-03.ibm.com/systems/bladecenter/resources/powerconfig.htmlv The input voltage is 100 - 127 V ac or 200 - 240 V ac auto-sensing.Statement 8CAUTION:Never remove the cover on a power supply or any part that has the followinglabel attached.Hazardous voltage, current, and energy levels are present inside any componentthat has this label attached. There are no serviceable parts inside thesecomponents. If you suspect a with one of these parts, contact a servicetechnician.To install a fixed power supply, complete the following steps:Note: You must install the fan assembly before removing or installing the powersupply.1. Read the safety information that begins in Safety and “Installation guidelines”on page 36.Attention: Static electricity that is released to internal server componentswhen the server is powered-on might cause the server to halt, which mightresult in the loss of data. To avoid this potential problem, always use anelectrostatic-discharge wrist strap or other grounding system when you workinside the server with the power on.2. Turn off the server (see “Turning off the server” on page 24) and all attachedperipheral devices. Disconnect the power cord; then, disconnect all externalcables from the server.3. Unlock and remove the left side cover (see “Removing the left-side cover” onpage 39).4. Remove the air baffle (see “Removing the air baffle” on page 41).5. Touch the static-protective package that contains the fixed power supply toany unpainted metal surface on the server; then, remove the power supplyfrom the package and place it on a static-protective surface.Chapter 2.
