HP E2492A Probe Adapter for
the Intel Deschutes Processor

Installation at a Glance
This Installation Guide explains how to install Hewlett-Packard’s
probe adapter for Intel Deschutes processors. This probing system
provides a quick and reliable connection from a Deschutes processor
to the HP E2487A Preprocessor Interface. The probe adapter contains
equipment and procedures for connecting to both slot 1 and slot 2
Deschutes processors.
Installation Overview
•Remove the processor card from the S.E.C. cartridge.
•Install the probe adapter assembly onto the processor card.
•Insert the processor card back onto the target system.
•Connect the preprocessor interface to the probe adapter.

Minimum Equipment Required
•A target system with the processor card removed from the S.E.C.
cartridge. Detailed instructions for disassembling the S.E.C.
cartridge can be found in Intel’s S.E.C. Cartridge Disassembly
Application Note.

To disassemble the slot 1 S.E.C. cartridge
The slot 1 S.E.C. cartridge consists of a thermal plate, skirt, cover, and
processor card. The thermal plate, skirt, and cover must be removed to
access the processor card.
Detailed instructions for disassembling the slot 1 S.E.C. cartridge can be
obtained from Intel. The following procedures are only intended as an
overview.
Disassembling the S.E.C. cartridge voids the Intel warranty. Also, thereis ahigh
probability that the coverand thermal plate willbe destroyed during
disassembly, and a small possibility that the processor card will be destroyed.
The S.E.C. cartridge isnotintended to be reassembled after disassembly.
1Remove the slot 1 S.E.C. cartridge from the target system by pushing
in the two tabs on top of the cartridge, then pulling the cartridge up.

2Using the instructions in the Intel S.E.C. Cartridge Disassembly
Application Note, insert a 1/8" small flat blade screwdriver between
the cover and the thermal plate, next to one of the four barbed posts
located at each corner of the thermal plate. Twist the screwdriver
until the barbed post pops free. Repeat this procedure for the other
barbed post at the same end of the cartridge, then repeat for the
other end of the cartridge.

3Using the instructions in the Intel S.E.C. Cartridge Disassembly
Application Note, separate the tabs on the thermal plate away from
the locator pins with fine-tip round nose pliers. Remove the spring
retainer clips, then separate the thermal plate from the processor
card.
4Remove any excess thermal grease from the processor heat spreader.
CAUTION Do not allow any thermal grease to get on the pads on top of the
microprocessor. The thermal grease could create an open electrical
connection between the probe head and the microprocessor.

To disassemble the slot 2 S.E.C. cartridge
The slot 2 S.E.C. cartridge consists of a thermal plate, skirt, cover, and
processor card. The thermal plate, skirt, and cover must be removed to
access the processor card.
Detailed instructions for disassembling the slot 2 S.E.C. cartridge can be
obtained from Intel. The following procedures are only intended as an
overview.

1Remove the slot 2 S.E.C. cartridge from the target system by pushing in the
two tabs on top of the cartridge, then pulling the cartridge up.

4Remove any excess thermal grease from the processor heat spreader.
CAUTION Do not allow any thermal grease to get on the pads on top of the
microprocessor. The thermal grease could create an open electrical
connection between the probe head and the microprocessor.

To connect to the slot 1 Deschutes target system
The Deschutes probe adapter connects to the slot 1 processor card once the
processor card has been removed from the S.E.C. cartridge.

1To prevent equipment damage, remove power from the target system.
2Install the interposer on the microprocessor on the processor card.
The alignment tabs on the interposer aid in making proper alignment.
Ensure that pin A1 is oriented correctly (see figure below).
CAUTION Serious damage to the target system or preprocessor interface can result
from incorrect connection. Note the position of pin A1 on the preprocessor
interposer and on the microprocessor before making any connection.

3Loosen the screw on the underside of the bottom clamp.
4Work the four clamp posts of the bottom clamp through the holes in
the processor card.

5Place the probe head onto the interposer using the three alignment
pins of the interposer and the three alignment holes of the probe
head as shown in the figure below.

6Move the top sliding clamp forward on the probe end until it holds
the clamp posts of the bottom clamp.
7Tighten the screw on the underside of the bottom clamp.
If the screw is too loose, the probe head will not make good contact with the
microprocessor pins.

8Insert the heat sink into the rectangular opening on top of the
preprocessor interface. Tighten the two screws until the heat sink is
snug. Do not over tighten.
Connecting the Heat Sink
9Connect the heat sink fan to a +12 Volt power source.
The black wire is ground, and the red wire is positive. To protect your target
system, ensure the fan is running whenever the target system is powered.
CAUTION This fan only operates on 12 Vdc. The remaining fans require 5 Vdc. Failure
to connect the fans to the appropriate power source will damage the fans,
and could cause overheating.

the assembled Deschutes probe package into the slot until the
connector is fully seated.
Slot1 Final ConnectionProcedure
You are now ready to connect the Deschutes probe to the HP E2487A
Preprocessor Interface. Refer to the HP E2487A Preprocessor Interface
