5.
Use the thermal-grease syringe to place 9 uniformly spaced dots
1
of 0.02 mL each on the top of the
microprocessor
2
. Make sure that the outermost dots are within 5 mm of the edge, to ensure even
distribution.
Note:
0.01mL is one tick mark on the syringe. If the grease is properly applied, approximately half
(0.22 mL) of the grease will remain in the syringe.
6.
Install the heat sink onto the microprocessor as described in “Installing the microprocessor” on page
141.
Replacing the system board
To replace the system board, use the following procedures:
Removing the system board
Note:
When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware that the customer provides on a diskette or CD image. Make sure that
you have the latest firmware or a copy of the pre-existing firmware before you proceed.
To remove the system board, complete the following steps
1.
Read the safety information in “Important Safety Information” on page 1 and “Guidelines for trained
service technicians” on page 115.
2.
Turn off the server and any attached devices.
3.
Turn off the peripheral devices and disconnect all power cords; then, remove the cover (see
“Removing and installing the cover” on page 119).
Note:
When you replace the system board, you must either update the server with the latest
firmware or restore the pre-existing firmware that the customer provides on a diskette or CD image.
Make sure that you have the latest firmware or a copy of the pre-existing firmware before you
proceed.
4.
Remove the riser-card assembly (see “Removing the riser-card assembly” on page 157).
5.
Remove the IBM ServeRAID-BR10il SAS/SATA controller if one is installed (see “Removing an IBM
ServeRAID-BR10il SAS/SATA Controller” on page 159).
6.
Remove the DIMM air baffle (see “Removing and installing the DIMM air baffle” on page 121).
7.
Remove the heat sink and microprocessor, and set them aside on a static-protective surface for
reinstallation (see “Removing the microprocessor” on page 140).
