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.
