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 “Replacing amicroprocessor and heat sink” on page 243.Installing a hot-swap ac power supplyUse this information to install a hot-swap ac power supply.About this taskThe following items 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 The server comes standard with one 750-watt or 900-watt hot-swap powersupply. The input voltage is 110 V ac or 220 V ac auto-sensing.Note: You cannot mix 110 V ac and 220 V ac, or 750-watt and 900-watt powersupplies in the server, it is not supported.v These power supplies are designed for parallel operation. In the event of apower-supply failure, the redundant power supply continues to power thesystem. The server supports a maximum of two power supplies.v The server can run fully configured with one power supply. For redundancysupport, you must install the second hot-swap power supply.Note: You cannot mix high-efficiency and non-high-efficiency power supplies inthe server.Statement 5CAUTION: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 current fromthe device, ensure that all power cords are disconnected from the power source.12Figure 59.
