IBM system x3530 m4 (7160k2g, 90y8826 х4, 49y3760, 00d4413) [370/402] Removing the system board

3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat

sink.

Note: Make sure that all of the thermal grease is removed.

4. Use a clean area of the cleaning pad to wipe the thermal grease from the

microprocessor; then, dispose of the cleaning pad after all of the thermal grease

is removed.

5. Use the thermal-grease syringe to place 9 uniformly spaced dots of 0.02 mL

each on the top of the microprocessor. The outermost dots must be within

approximately 5 mm of the edge of the microprocessor; this is to ensure

uniform distribution of the grease.

Note: If the grease is properly applied, approximately half of the grease will

remain in the syringe.

6. Install the heat sink onto the microprocessor as described in “Installing an

additional microprocessor and heat sink” on page 50.

Removing the system board

Note:

1. Before you replace the system board, make sure that you backup any features

on demand (FoD) keys that were enabled. Remember to re-enable the features

on demand (FoD) keys after installing the new system board. For more

information on Features on Demand (FoD), including instructions for

automating the activation and installation of the activation key by using IBM

ToolsCenter or IBM Systems Director, see the IBM Features on Demand User's

Guide at https://www-304.ibm.com/systems/x/fod/index.wss under the Help

section.

2. When you replace the system board, you must either update the server with

the latest firmware or restore the pre-existing firmware from a diskette or CD

image. Make sure that you have the latest firmware or a copy of the

pre-existing firmware before you proceed.

Before you remove the system board from the server, take the following steps to

save data, firmware, and configuration data:

v Record all system configuration information, such as IMM IP addresses, vital

product data, and the machine type, model number, serial number, Universally

Unique Identifier, and asset tag of the server.
