Removing a microprocessor and heat sink
Use this information to remove a microprocessor and heat sink.
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 a 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.
The following notes describe information that you must consider when you remove a microprocessor:
- A socket cover and heat-sink filler or a microprocessor and heat sink must always be installed on microprocessor sockets 1, 3, and 4. Microprocessor socket 2 will only have a socket cover when a microprocessor is not installed. If the compute node has only one microprocessor, it must be installed in microprocessor socket 1.
- 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 installing a second microprocessor, the option kit comes with a microprocessor installation tool that you must use when you install a microprocessor. The microprocessor installation tool comes with the replacement microprocessor installed on it and a cover over the microprocessor.
- 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.
- If you are replacing a defective microprocessor, you must obtain the following items for use during the replacement procedure (see Parts listing, Types 7167 and 2590):
- Alcohol wipes
- Thermal grease
Note
Be sure to use the installation tool that comes with your microprocessor installation tool assembly. The tools are similar in function and design, however Tool A has one setting for installing one size of microprocessor, and supports the following families of microprocessors: E5-26xx, E5-46xx. Installation Tool B has two settings for installing two different sizes of microprocessors. The settings that are marked on Tool B are
Lfor smaller low core microprocessors, and
Hfor larger high core microprocessors. Installation Tool B supports the following families of microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2.
