  • Power off the server and disconnect all power cords for this task.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

  • It may take some time for the heat sink to cool down after the system has been powered down.

  • The heat sink is necessary to maintain proper thermal conditions for the processor. Do not power on the server with the heat sink removed.
