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.

Equipment Supplied

•Probe adapter

•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 the probe adapter to the HP E2487A Preprocessor Interface

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.

4Loosen the adjustment screws to ensure that there will be adequate

clearance once you connect the assembly to the target system.

5Attach the fully-connected probe adapter/Instrumented Mobile

Module assembly to the connectors on the mother board.

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.

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
