IBM 220 manual b. Align and place the fan sink on top of the microprocessor

9.If you are installing a microprocessor that has a speed of 933 MHz or higher, install a fan sink onto the microprocessor and connect the fan-sink power cable to the system board:

Terminator card

VRM 2 (J12)

	Microprocessor
	fan 1 (J2)
	Microprocessor
	fan 2 (J3 )
Microprocessor
	VRM 1
Fan sink	(J42)

Fan-sink retainer

a.Peel the plastic protective strip off the bottom of the fan sink. Make sure that the square of thermal material is still on the bottom of the fan sink.

b.Align and place the fan sink on top of the microprocessor.

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 retainer.

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:

•If you installed the microprocessor in connector U11, connect the fan- sink power cable to connector J2.

•If you installed the microprocessor in connector U12, connect the fan- sink power cable to connector J3.

10.Place the terminator card in the static-protective package that your 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.

11.Install the VRM that is included in the microprocessor kit. Attention: Use of other VRMs might cause your server to overheat.

a.Center the VRM over the appropriate VRM connector:

(1) If you installed the microprocessor in connector U11, press down on the latches on either side of connector J12, and install the VRM in connector J12.
