Installing Internal Optional DevicesExpress5800/T120h User’s Guide68Chapter 2 Preparations1.10 High-performance CPU Heat Sink ModuleA high-end heat sink module for CPU is required if you use certain types of CPU. Even if you use a type of CPUwhich is operable with a standard heat sink, you can reduce the electricity consumption of fan by using ahigh-end heat sink module for CPU.The electricity consumption of fan changes depending on the configuration of server and the workloads.It isoptimized in accordance with the amount of workloads, the density of configuration, the expansion of peripheralconfiguration, etc.For the list of CPUs supports high-performance CPU heat sink module, refer to the web site of NECHandling precautinsTo prevent personal injury, electrical shock or equipment damage, unplug the power cord and ensure no poweris supplied to the server.You cannot turn off the system power supply completely by the power button of the server. Until the AC powercord is unplugged, the power supply circuit is still active in some parts of the machine.InstallationBefore installing a high-end heat sink module for CPU, prepare the followings. Parts included in the optional processor heat sink kit T-30 hexalobular driver 1/4-inch wide flat-blade screwdriverTo install the components, follow these steps.Note In order to avoid the damage to the processor and the mother board, take care onlyauthorized persons change or install a processor.Note In order to prevent the malfunctions of server and the damage to devices, useprocessors with the same parts number if you adopt multiprocessor configuration.Note If you intend to actuate a processor at faster speed, update the system ROMbefore installing a processor.
