When servicing the components in this section, unplug the AC power cords and use ESD protection.
Use this procedure when replacing a failed CPU to remove a heatsink and CPU.
Before You Begin
For serviceability considerations, see Component Serviceability.
For fan module designation information, see Component Designations.
Turn the screws alternately one and one half turns until they are fully removed.
A thermal compound applied to the top of the CPU to facilitate heat transfer to the heatsink also acts as an adhesive.
Do not allow the thermal compound to contaminate other components. Retain the heatsink. You need to reuse it.
Caution - Component damage. Failure to clean the thermal compound from the heatsink and the CPU prior to removing the CPU could result in accidental contamination of the CPU socket, the removal tool, or other components. Also, be careful not to get the grease on your fingers as this could result in contamination of components. |
To access the CPU, the CPU load plate needs to be opened. The load plate is locked in its closed position by the load plate lever.
The levers are numbered by their required order of operation. The left-side lever (when viewed from the front of the server) must be opened first.
When the second lever is in its fully-open position, the load plate is unlocked.
Caution - Component damage. The pins of the CPU socket can be easily damaged. To remove the CPU, use the correct CPU replacement tool. |
The tool is used to remove and install the CPU in the socket. The top side of the replacement tool has a button in the center and a tab on one side. Pressing down on the button opens the tool. Pressing the tab closes the tool (and releases the button).
This action opens the tool.
On one corner of the tool there is a label with a downward pointing triangle. Likewise, the CPU is marked with a triangle on one of its corners. This is a key that aids in correctly positioning the tool and the CPU with the CPU socket. The tool and the CPU are correctly positioned with the socket when all of the triangles are aligned.
This action is accompanied by a click sound as the tool closes and grabs the CPU.
This action is accompanied by a click sound as the tool releases its hold on the CPU.
