i. Rotate the locking lever on the microprocessor socket to the closed and locked position. Make
sure that the lever is secured in the locked position by pressing the tab on the microprocessor
socket.
Step 3. Install a heat sink on the microprocessor.
Attention:
• Do not set down the heat sink after you remove the plastic cover.
• Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material
will contaminate it. If the thermal material on the microprocessor or heat sink becomes
contaminated, contact your service technician.
a. Remove the plastic protective cover from the bottom of the heat sink.
b. Make sure that the thermal material is still on the bottom of the heat sink; then, align and place
the heat sink on top of the microprocessor in the retention bracket, thermal material side
down. Press firmly on the heat sink.
c. Align the three screws on the heat sink with the holes on the heat-sink retention module.
d. Press firmly on the captive screws and tighten them with a screwdriver, alternating among
the screws until they are tight. If possible, each screw should be rotated two full rotations at
a time. Repeat until the screws are tight. Do not overtighten the screws by using excessive
force. If you are using a torque wrench, tighten the screws to 8.5 Newton-meters (Nm) to 13
Nm (6.3 foot-pounds to 9.6 foot-pounds).
Step 4. Reinstall the memory module or DIMM filler closest to the microprocessor you installed.
a. If you installed microprocessor 1, install the memory module into DIMM connector 1 (see
“Installing a memory module” on page 24).
b. If you installed microprocessor 2, install the memory module into DIMM connector 6 (see
“Installing a memory module” on page 24).
Step 5. If you are using a single microprocessor, make sure that memory modules are installed in DIMM
socket 2 and DIMM socket 6. If two microprocessors installed in the blade server, make sure that
memory modules are installed in DIMM socket 2, DIMM socket 6, DIMM socket 8, and DIMM
socket 12. See “Installing a memory module” on page 24 for more information on installing a
memory module.
Step 6. Install the optional expansion unit, if you removed one from the blade server to replace the battery
(see “Installing an optional expansion unit” on page 21 for instructions).
Thermal grease
Use this information to determine the guidelines for using thermal grease on a heat sink and processor.
The thermal grease must be replaced whenever the heat sink has been removed from the top of the
microprocessor and is going to be reused or when debris is found in the grease.
To replace damaged or contaminated thermal grease on the microprocessor and heat sink, complete the
following steps:
Step 1. Place the heat-sink assembly on a clean work surface.
Step 2. Remove the cleaning pad from its package and unfold it completely.
Step 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.
