11. If you are reinstalling a heat sink that was removed from the blade server,
complete the following steps:
Attention:
v
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.
v
Do not touch exposed pins of the microprocessor socket.
a. Make sure that the thermal material is still on the bottom of the heat sink
and on the top of the microprocessor.
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 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).
12. If you are installing a new heat sink, complete the following steps:
Attention:
v
Do not set down the heat sink after you remove the plastic cover.
v
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.
v
Do not touch exposed pins of the microprocessor socket.
a. Remove the plastic protective cover from the bottom of the heat sink.
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 1.13 ± 0.13 Newton-meters
(Nm) (10 ± 0.15 in-lbs).
13. Make sure that, at a minimum, memory modules are installed in DIMM
connectors 1 and 4. See “Installing a DIMM - BladeCenter HX5” on page 39
for more information on installing a memory module.
14. Install the access panel if you removed it earlier.
