HP E2494A Probe Adapter for
the Intel Pentium®II Mobile
Processor

Installation at a Glance
This Installation Guide shows how to connect Hewlett-Packard’s
HP E2494A Probe Adapter to an Intel Mobile Pentium®II processor.
This probe adapter provides a quick and reliable means of connecting
the HP E2487A Preprocessor Interface to supported target systems,
using the 190-pin Mictor connector. The supported target systems
include the Pentium II Instrumented Mobile Module, and the Pentium
II Mobile Processor mounted on Intel’s Instrumented Interposer board.
Installation Overview
•Connect the preprocessor interface to the probe adapter.
•Connect the probe adapter to the target system 190-pin Mictor
connector, and adjust the adjustment screws.

•This Installation Guide
Minimum Equipment Required
•For target systems using a Pentium II Mobile Module, a Pentium II
Instrumented Mobile Module is required.
•For target systems using a Pentium II Mobile Processor, an
Instrumented Interposer board is required.

To connect the probe adapter to the HP E2487A
Preprocessor Interface
The probe adapter has five high-density connectors, labeled Cable P1
through Cable P5. The HP E2487A Preprocessor Interface also has five
high-density cables, labeled P1 through P5. Connect the preprocessor cables
to the correspondingly-numbered probe adapter connectors.
CAUTION To prevent equipment damage, you must connect the preprocessor interface
cables to the probe adapter before connecting the probe adapter to the
target system.
CAUTION To prevent equipment damage, when disconnecting the preprocessor
interface from the probe adapter use the procedure on page 11.

To connect to the target system
The HP E2494A probe adapter connects to both the Pentium II Instrumented
Mobile Module, and the Pentium II Mobile Processor mounted on Intel’s
Instrumented Interposer board, using the 190-pin Mictor connector. The
probe adapter connects to both types of target systems in a similar manner.
You musthave the appropriate board for connecting the HP E2494Ato your
targetsystem. For target systems using a Pentium IIMobile Module, aPentium
II InstrumentedMobile Module is required. For target systems using a Pentium
II Mobile Processor, an Instrumented Interposer board is required. These
boardshave the 190-pin Mictor connectorsmounted on them. Theyare
availablefrom Intel.
Connecting to Pentium II Instrumented Mobile Module systems
CAUTION To protect your equipment, remove the power from both the preprocessor
interface and the target system before you make or break connections.
1Remove the Pentium II Instrumented Mobile Module board from the
target system.
2Connect the HP E2487A preprocessor interface cables to the
HP E2494A probe adapter, as shown on page 4.
CAUTION Connecting the preprocessor interface cables to the probe adapter after the
probe adapter is already connected to the mobile module may exert
excessive stress on the mobile module and the probe adapter. Excessive
stress can damage the mobile module and/or the probe adapter.

3Plug the probe adapter into the 190-pin Mictor connector on the
Pentium II Instrumented Mobile Module, ensuring that Pin 1 is
properly aligned (see illustration below).
CAUTION Damage to the connectors on the target system and probe adapter can result
from incorrect connection. Note the position of Pin 1 of the 190-pin Mictor
connectors on the probe adapter and the Instrumented Mobile Module board
prior to making any connection. Take care to align the probe adapter
connector with the pins on the Instrumented Mobile Module board
connector so that all pins are making contact. Also, ensure that the probe
adapter is firmly seated in the 190-pin Mictor connector, and that the probe
adapter is parallel within ±4°with the Pentium II Instrumented Mobile
Module.

6Adjust the screws until they are making contact with the mother
board. Ensure that the probe adapter is firmly seated in the 190-pin
Mictor connector, and that the probe adapter is parallel within ±4°
with the mother board (see below).
CAUTION The adjustment screws must be properly adjusted so that they are touching
the mother board, and the probe adapter is parallel within ±4°with the
mother board. If the probe adapter is not supported by the adjustment
screws, or if the probe adapter is not seated so that it is parallel within ±4°
with the mother board, damage may occur to the Mictor connectors.

Instrumented Interposer board
CAUTION To protect your equipment, remove the power from both the HP E2487A
Preprocessor Interface and the target system before you make or break
connections.
1If you are already using an Instrumented Interposer board, remove
the Instrumented Interposer board from the target system. If you are
not already using an Instrumented Interposer board, remove the
microprocessor from the target system and plug it into the
Instrumented Interposer board.
2Connect the HP E2487A preprocessor interface cables to the
HP E2494A probe adapter, as shown on page 4.
CAUTION Connecting the preprocessor interface cables to the probe adapter after the
probe adapter is already connected to the interposer board may exert
excessive stress on the interposer board and the probe adapter. Excessive
stress can damage the interposer board and/or the probe adapter.
3Loosen the adjustment screws to ensure that there will be adequate
clearance once you connect the probe adapter to the Instrumented
Interposer board.
