Chapter 5 Servicing FRU Components 5-7
a. If you are reusing an existing cleaned heatsink, use the syringe (supplied
with the new or replacement CPU) to apply thermal grease on top of the CPU
in a star pattern.
Note – You do not need to complete this step if you have a new heatsink since new
heatsinks come with thermal grease already applied.
b. Orient the heatsink so that the two screws line up with the mounting studs.
Caution –
When handling the heatsink, be careful not to get the thermal grease on
your fingers so as not to transfer the grease to other server components. To do so
could cause component contamination and/or damage.
c. Carefully position the heatsink on the CPU, aligning it with the mounting
posts to reduce movement after it makes initial contact with the layer of
thermal grease.
Caution –
If the heatsink assembly is moved too much during its installation, the
layer of thermal grease might not be distributed evenly, leading to component
damage.
d. Tighten the screws alternately one-half turn until fully seated.
4. Return the server to operation:
a. Install the top cover.
See Section 6.1 “Replacing the Server Top Cover” on page 6-1 .
b. Return the server to the normal rack position.
See Section 6.2 “Returning the Server to the Normal Rack Position” on page 6-2 .
c. Reconnect all power cords to the server power supplies and power on the
server.
See Section 6.3 “Powering On the Server” on page 6-3 .
5. If the CPU being installed is replacing a faulty CPU, manually clear the CPU
fault using Oracle ILOM.
For instructions on clearing server faults, refer to the Oracle Integrated Lights Out
Manager (ILOM) 3.1 Users Guide .
