Perform the steps below before you open the server or before you remove or replaceany
component.
• Back up all important system and data files before performing any hardwareconfiguration.
• Turn off the system and all the peripherals connected to it.
• Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
• Apply an even and thin layer of thermal grease on the surface of the CPU.
• Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage
of the CPU may occur.
• Set the CPU host frequency in accordance with the CPU specifications. It is not recommended
that the system bus frequency be set beyond hardware specifications since it does not meet the
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specifications, please do so according to your hardware specifications including the CPU,
graphics card, memory, hard drive, etc.
