Removing a microprocessor and heat sink - Flex System x280 X6, x480 X6, and x880 X6 Compute Node Types 7903 and 4259

Use this information to remove a microprocessor and heat sink.

Before you begin

Note: This procedure should be performed only by trained service technicians.

Before you remove the microprocessor and heat sink, complete the following steps:

Read Safety and Installation guidelines.
If the compute node is installed in an Flex System chassis, remove it (see Removing a compute node from a chassis for instructions).
Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.

About this task

The following notes describe information that you must consider when you remove a microprocessor:

Each microprocessor socket must always contain a microprocessor and heat sink.
The microprocessor installation tool might become worn after several uses. Make sure that the tool can hold the microprocessor securely if you are reusing an existing microprocessor installation tool. Do not return the tool with other parts that you are returning.
If you are replacing a defective microprocessor, you must obtain the following items for use during the replacement procedure (see Parts listing, Types 7903 and 4259):
- Alcohol wipes
- Thermal grease
If you are replacing a defective microprocessor, the CRU kit comes with one installation tool with the replacement microprocessor installed on it and a cover over the microprocessor, and one empty installation tool without a cover.
The microprocessor installation tool has the microprocessor installed on the tool, and may have a protective cover over the microprocessor. Do not use the tool, or remove the cover until you are instructed to do so.
Note: Be sure to use the installation tool that comes with your microprocessor installation tool assembly.

Procedure

To remove a microprocessor and heat sink, complete the following steps:

Remove the cover (see Removing the compute node cover).
Locate the microprocessor that is to be removed (see System-board connectors).
Remove the solid state drives (see Removing a solid state drive).
Remove the solid state drive mounting sleeve (see Removing the solid state drive mounting sleeve).
Remove the solid state drive cage and backplane (see Removing the solid state drive cage and backplane).
Remove the hot-swap hard disk drives and hard disk drive bay fillers (see Removing a hot-swap hard disk drive).
Remove the hard disk drive cage and backplane assembly (see Removing the hard disk drive cage and backplane assembly).
Remove the heat sink.
Attention: Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material will contaminate it.
1. Use a screwdriver to loosen the screw on one side of the heat sink to break the seal with the microprocessor.
2. Use a screwdriver to loosen the screws on the heat sink, rotating each screw two full turns until each screw is loose.
3. Gently pull the heat sink from the microprocessor and pivot the heat sink from the standoff.
Attention: Do not use any tools or sharp objects to lift the release levers on the microprocessor socket. Doing so might result in permanent damage to the system board.
Open the microprocessor socket release levers and retainer.
1. Identify which release lever is labeled as the first release lever to open, and open it.
2. Open the second release lever on the microprocessor socket.
3. Open the microprocessor retainer.
Attention: Do not touch the connectors on the microprocessor and the microprocessor socket.
Remove the microprocessor from the socket:
Note: If you are replacing a microprocessor, use the empty installation tool that comes with the CRU kit to remove the microprocessor.
1. Twist the handle on the microprocessor tool counterclockwise so that it is in the open position.
2. Align the installation tool with the screws on the microprocessor socket, and lower the tool on the microprocessor. The installation tool rests flush on the socket only if it is aligned correctly.
3. Twist the handle on the installation tool clockwise and lift the microprocessor out of the socket.

What to do next

If you are instructed to return the microprocessor and heat sink, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
