Note: If the grease is properly applied, approximately half of the grease willremain in the syringe.6. Install the heat sink onto the microprocessor as described in 11 on page 104.If you have other options to install or remove, do so now. Otherwise, go to“Completing the installation” on page 109.Installing a hot-swap power supplyThe following notes describe the type of ac power supply that the server supportsand other information that you must consider when you install a power supply:v Make sure that the devices that you are installing are supported. For a list ofsupported optional devices for the server, see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Before you install an additional power supply or replace a power supply with oneof a different wattage, you may use the IBM Power Configurator utility todetermine current system power consumption. For more information and todownload the utility, go to http://www-03.ibm.com/systems/bladecenter/resources/powerconfig.html.v The server comes with one hot-swap 12-volt output power supply that connectsto power supply bay 1. The input voltage is 110 V ac or 220 V ac auto-sensing.v Power supplies in the server must be with the same power rating or wattage toensure that the server will operate correctly.v Power supply 1 is the default/primary power supply. If power supply 1 fails, youmust replace the power supply with the same wattage immediately.v You can order an optional power supply for redundancy.v These power supplies are designed for parallel operation. In the event of apower-supply failure, the redundant power supply continues to power the system.The server supports a maximum of two power supplies.Statement 5:CAUTION:The power control button on the device and the power switch on the powersupply do not turn off the electrical current supplied to the device. The devicealso might have more than one power cord. To remove all electrical currentfrom the device, ensure that all power cords are disconnected from the powersource.Statement 8106 IBM System x3500 M4 Type 7383: Installation and User’s Guide
