b. 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 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 17. Make sure that, at a minimum, memory modules are installed in DIMM connectors 1 and 4. See
“Installing a DIMM - BladeCenter HX5” on page 104 for more information on installing a memory
module.
Step 18. Install the access panel if you have standard heat sinks installed.
Note: If you have the tall heat sinks installed, you do not need to install the access panel.
a. Make sure that the screws on the access panel are in the open position (the screw insert is
parallel to the side of the access panel).
b. Slide the back of the cover under the blade server bezel, aligning the screws with the slots on
the blade server.
c. Using a screwdriver or a coin, turn each of the screws away from the middle of the blade
server until it is in the locked position.
Step 19. If the blade server is part of a scalable blade complex, assemble the scalable blade complex (see
“Assembling a scalable blade complex” on page 70 for instructions).
Step 20. Install the IBM MAX5 expansion blade if you removed one (see “Installing an IBM MAX5 expansion
blade” on page 88 for instructions).
Step 21. Install the optional expansion unit, if you removed one from the blade server (see “Installing an
expansion unit” on page 97 for instructions).
