5. With the heat-exchanger assembly at an angle as shown in the illustration,
carefully align the heat-exchanger assembly with the microprocessor and the
heat exchanger retention module (socket) on the system board. Make sure that
the alignment pins (the two heat-exchanger nibs that are closer to the
microprocessor) protrude through the alignment hole (the opening in the side
of the heat-exchanger bracket) and that the flange of the heat sink rests under
the lip of the heat-exchanger socket.
6. Gently press the assembly into place.
7. Close the heat-exchanger-assembly release latch, catching it under the hook
on the socket.
8. Replace the air baffle (see “Installing the air baffle” on page 78).
9. Install the cover (see “Installing the cover” on page 61).
10. Slide the server into the rack.
11. Connect the cables and power cords.
12. Turn on all attached devices and the server.
Thermal grease
The thermal grease must be replaced whenever the heat exchanger 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 exchanger, complete the following steps:
1. Place the heat-exchanger assembly on a clean work surface.
2. Remove the cleaning pad from its package and unfold it completely.
3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat
exchanger.
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.
