a. Peel the plastic protective strip off the bottom of the heat or the fan sink. Make sure the square of thermal material is still on the bottom of the heat sink or fan sink; if not, replace the it with a new heat sink or fan sink. b. Align and place the heat sink or the fan sink on top of the microprocessor. c. Locate the tab on the front of the microprocessor socket (the side facing the PCI slots). Then, press down and latch the retainer onto the tab. d. Locate the tab on the rear of the microprocessor socket (the side facing the power supply). Then, press down and latch the retainer onto the tab. e. If you have installed a fan sink, connect the fan-sink power cable to the microprocessor fan-sink connector (CPUFA1) on the system board. See "System board internal cable connectors" on page 38 for the location of the microprocessor fan-sink connector. Note: Make sure the cable is not in a position to interfere with the fan sink operation. 7. If you have other options to install or remove, do so now. 8. Replace the support-bracket assembly and reconnect the fan cable to the connector (SYSFA1) on the system board. See "Removing the support bracket assembly" on page 45 for details. See "System board internal cable connectors" on page 38 for the location of the fan cable connector. 9. Reinstall the side cover. See "Installing the cover" on page 62. 10. Reconnect the external cables and power cords; then, turn on the peripheral devices and the server. 60 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

a.
Peel
the
plastic
protective
strip
off
the
bottom
of
the
heat
or
the
fan
sink.
Make
sure
the
square
of
thermal
material
is
still
on
the
bottom
of
the
heat
sink
or
fan
sink;
if
not,
replace
the
it
with
a
new
heat
sink
or
fan
sink.
b.
Align
and
place
the
heat
sink
or
the
fan
sink
