Protecting the Interposer
Here is a summary of precautions to take to avoid damaging the interposer:
DO minimize the removal of the analysis probe cables, once they are connected
to the interposer.
DO minimize the removal of the interposer, once it is connected to the
microprocessor and target system.
DO exercise patience and care when working with the interposer.
DO use ESD precautions.
DO remove power from the target system and analysis probe before making
attachments.
DO protect the pins from damage by covering them with the pin protector when
the interposer is not in use.
DO NOT insert any kind of tool between the interposer and the microprocessor,
except as described in this manual.
DO NOT kink the analysis probe cables.
DO NOT pull on or twist the "wings" of the interposer.

1Remove the heatsink from the microprocessor.
2Remove the microprocessor from the target system.
3Remove the Intel retention module from the target
system.
4Install the Agilent retention modules.

5Check that the socket on the target system is still
open.
6Remove the pin protector from the interposer.
Keep the pin protector. You will need it to prevent damage to the interposer
whenever the interposer is not plugged into the target system.

7Align the interposer over the socket on the target
system.
Note how the socket on the interposer is rotated 80° relative to the socket on
the target system. This is done so that the interposer will not interfere with
the target socket’s actuation mechanism.
The wings of the interposer will flex around the retention modules.
8Gently wiggle the interposer until you feel the pins
fall into the holes of the socket.
9Visually check that the bottom of the interposer is
flush with the top of the socket on the target
system.

10 With one hand, apply light downward pressure on
the interposer. With the other hand, close the the
socket.
11 Align the processor over the socket on the
interposer.
12 Gently wiggle the assembly until you feel the pins
fall into the holes. Visually check that the bottom of
the processor module is flush with the top of the
socket on the interposer.
CAUTION
The processor should be oriented the same way that it was originally oriented
on the target system. Note that the orientation of the processor with respect to
the lever on the socket is opposite from the target system. The socket is keyed,
so the processor will only go in the right way.

13 Apply light downward pressure on the processor
while you close the interposer socket.
14 Re-install the heatsink.

15 Install the clip assembly to hold the heatsink in
place.
Use the clip assembly which you removed earlier.

16 Connect the analysis probe cables to the interposer.
Refer to the silkscreened labels on the interposer and on the cable paddles.
Install the supplied clips to keep the paddles on the end of the analysis probe
cables from pulling apart.
17 Connect the analysis probe to the logic analyzer.
Connect the pod cables to the connectors on the analysis probe as shown on
the back of the analysis probe.
