Caution - Processors should be removed only by authorized Oracle Services personnel.
Caution - Processor removal and replacement must be done using the removal and replacement tool that is included with the replacement processor for the controller (see Remove a Processor). Using a tool with a different color code might result in damage to the processor and processor socket.
The processor fault LEDs are located next to the processor(s).
If the processor fault LED is off, then the processor is operating properly.
If the processor fault LED is on (amber), then the processor is failed and should be replaced.
Using a No. 2 Phillips screwdriver, turn the screws counterclockwise alternately one and one half turns until they are fully removed.
A thin layer of thermal grease separates the heatsink and the processor. This grease acts as an adhesive.
Be very careful not to get the thermal grease on your fingers.
Caution - Failure to clean the heatsink prior to removing the processor could result in the accidental contamination of the processor socket or other components. Also, be careful not to get the grease on your fingers as this could result in contamination of components.
Caution - Whenever you remove a processor, you should replace it with another processor and reinstall the processor heatsink; otherwise, the controller might overheat due to improper airflow. For instructions for installing a processor, see Install a Processor.
Caution - Before removing the processor, ensure that you are using the correct color-coded processor removal and replacement tool. For information on how to select the correct processor removal and replacement tool, see Selecting the Correct Processor Removal and Replacement Tool.
To properly position the tool over the processor socket, rotate the tool until the green triangle on the side of the tool is facing the front of the controller and it is over the left side of the processor socket when viewing the controller from the front.
An audible click indicates that the processor is engaged.
Caution - The following figure shows the green color-coded processor removal and replacement tool. If you are removing a 12-core processor, you must use the pink color-coded processor removal and replacement tool; otherwise, damage might result to the processor or the processor socket. For information on how to select the correct processor removal and replacement tool, see Selecting the Correct Processor Removal and Replacement Tool.
