7. Install a fan sink onto the microprocessor and connect the fan-sink power cable to the system board by doing the following: Terminator card VRM 2 (J12) Microprocessor fan 2 (J2) Microprocessor Fan sink Microprocessor fan 1 (J3 ) VRM 1 (J42) Fan-sink retainer a. Peel the plastic protective strip off the bottom of the fan sink. Make sure that the square of the thermal material is still on the bottom of the fan sink. b. Align and place the fan sink on top of the microprocessor. Note: Set the fan sink into place. Make sure the fan sink guide rib fits between the processor and the processor socket. c. Align and place the fan-sink retainer (clip) over the fan sink. d. Insert a small, flat-blade screwdriver into the tab on the fan sink. e. Press down and in with the screwdriver handle to snap the fan-sink retainer into place in the slot on the microprocessor, over the fan sink. f. Connect the built-in fan-sink power cable to the appropriate connector on the system board. v If you installed the microprocessor in connector (U11), connect the fan-sink power cable to connector (J2). v If you installed the microprocessor in connector (U12), connect the fan-sink power cable to connector (J3). 8. Place the terminator card in the static-protective package that the new microprocessor was shipped in, and store it in a safe place. You will need to install the terminator card again if you ever remove the microprocessor and do not replace it with another microprocessor. 9. Install the VRM that is included in the microprocessor kit. Attention: Use of other VRMs might cause the server to overheat. a. Center the VRM over the appropriate VRM connector: Installing options 63

Install a fan sink onto the microprocessor and connect the fan-sink power
cable to the system board by doing the following:
Terminator card
Microprocessor
fan 2 (J2)
Microprocessor
Microprocessor
fan 1 (J3 )
Fan sink
Fan-sink
retainer
VRM 1
(J42)
VRM 2
(J12)
a.
Peel the plastic protective strip off the bottom of the fan sink. Make sure
that the square of the thermal material is still on the bottom of the fan
sink.
b.
Align and place the fan sink on top of the microprocessor.
Note:
Set the fan sink into place. Make sure the fan sink guide rib fits
between the processor and the processor socket.
c.
Align and place the fan-sink retainer (clip) over the fan sink.
d.
Insert a small, flat-blade screwdriver into the tab on the fan sink.
e.
Press down and in with the screwdriver handle to snap the fan-sink
retainer into place in the slot on the microprocessor, over the fan sink.
f.
Connect the built-in fan-sink power cable to the appropriate connector on
the system board.
v
If you installed the microprocessor in connector (U11), connect the
fan-sink power cable to connector (J2).
v
If you installed the microprocessor in connector (U12), connect the
fan-sink power cable to connector (J3).
8.
Place the terminator card in the static-protective package that the new
microprocessor was shipped in, and store it in a safe place. You will need to
install the terminator card again if you ever remove the microprocessor and
do not replace it with another microprocessor.
9.
Install the VRM that is included in the microprocessor kit.
Attention:
Use of other VRMs might cause the server to overheat.
a.
Center the VRM over the appropriate VRM connector:
