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 a
microprocessor and heat sink” on page 92.
Removing the microprocessor 2 expansion board
To remove the microprocessor 2 expansion board, complete the following steps:
1. Read the safety information that begins in Safety and “Installation guidelines”
on page 36.
2. Turn off the server (see “Turning off the server” on page 24) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables from the server.
3.
Carefully turn the server on its side so that it is lying flat, with the cover
facing up.
Attention: Do not allow the server to fall over.
4. Unlock and remove the left-side cover (see “Removing the left-side cover” on
page 39)
5. Remove the air baffle (see “Removing the air baffle” on page 41)
6. Remove the fan assembly (see “Removing the fan assembly” on page 42)
7.
Note where the cables are connected to the microprocessor 2 expansion board;
then, disconnect them.
