Introduction

These instructions explain how to install or replace DRAM modules in the

PC9 Industrial PC or the P9 PowerStation. They include steps for disas-

sembling the unit, removing previously installed DRAM module(s),

installing new DRAM, and reassembling the unit.

Warning For safety reasons, the unit should be opened only by qualified

service personnel.

Warning Be sure to observe electrostatic discharge (ESD) precautions

while working inside the unit.

To complete this procedure, you will need the following items:

• The DRAM module(s) that you purchased:

• 32MB SDRAM DIMM (DIM-9032)

• 64MB SDRAM DIMM (DIM-9064

• 128MB SDRAM DIMM (DIM-9128)

• 256MB SDRAM DIMM(DIM-9256)

• Phillips-head screwdriver

Disassembling the Unit

To disassemble the unit, follow these steps:

1. Turn off the unit.

2. Disconnect the unit from the power source.

3. Disconnect all cables attached to the unit.

1. Line up the two notches in the side of the module with the tabs in-

side the socket, as shown below.

2. Press the module into the socket until the socket latches snap into

place.

Reassembling the Unit

To reassemble the unit, follow these steps:

1. Fit the two tabs in the top of the back cover into the two slots at the

top of the configuration bay, and slide the back cover onto the unit.

2. Fasten the back cover to the unit by replacing the four retaining

screws that you removed in step 4 on page 1.

3. Reconnect power and other cables to the unit.
