– All screws are not completely tightened.
• Do not move the secured heat sink.

Replacement / Removal
Important
• Do not remove any CPU unless it is failed.
• To remove the heat sink from the CPU, first turn the heat sink to the left
and right lightly to make sure that the heat sink can be apart from the CPU.
Removing the heat sink with it adhering to the CPU may cause the CPU
and/or CPU socket to be defected.
• If you fail to mount protective cover and dummy cover to the slot where
CPU is removed, the cooling effect in the server will deteriorate. It may
cause a malfunction of the server.
To remove CPU, reverse the installation procedure.
Perform the following steps if using the server with the CPU being removed.
1. Mount the protective cover to CPU socket.
2. Secure the dummy cover to the slot with four screws.
3. Remove the additional fan unit.
4. Mount the fan cover.
Perform the following steps after replacing or removing the CPU.
