Installation Procedures

Following are the procedures to install the HP A4350A Mass Storage Module upgrade in the Model

748i/64 or 748i/100 Ruggedized Workstation. or TELEPACE.

Prerequisites

The HP A4268A Fast Wide Differential SCSI Adapter must be installed on the Model 743 CPU board.

Refer to the Model A4268A Fast/Wide Differential SCSI Adapter Installation and Service Guide

(A4268–90600)

for installation instructions.

The Operating System must be HP–UX 9.05 or later.

Installation Procedures Overview

Installing the HP A4350A Mass Storage Module upgrade consists of the following procedures:

Prepare to install the mass storage module.

Power off the system.

Remove the existing mass storage module.

Install mass storage devices in the new mass storage module

Install the new mass storage module into the system, connect cables, and config-

ure system to include the FastWide SCSI devices.

Verify system operation.

Prepare to Install the Mass Storage Module Upgrade

Before upgrading the mass storage module, you should perform the following:

Unpack and verify kit contents. (See Kit Contents on previous page)

Observe Electrostatic Discharge (ESD) precautions.

Gather tools and accessories.

Observe Electr

ostatic Discharge Precautions

Electrostatic charges can damage the integrated circuits. To prevent such damage from occurring,

observe the following precautions when unpacking and installing the upgrade.

Stand on a static–free mat.

Wear a static strap to ensure that any accumulated electrostatic charge discharges

from your body to ground.

Connect all equipment together, including the static–free mat, static straps, and

all computer hardware.

Keep uninstalled printed circuit boards in their protective antistatic bags.

Handle printed circuit boards by their edges once you have removed them from

their protective antistatic bags.

Gather T

ools and Accessories

The tools required for the installation of the mass storage module upgrade kit are:

Flat–bladed screwdriver and Phillips Head screwdriver (not supplied with kit).

Grounding wrist strap supplied in the kit.

Anti–Static Bag supplied in the kit.

Mass Storage Module Configuration and Installation

The following provides the information for configuring and installing the new mass storage module.

Before configuring the new mass storage module, you need to know the type and location of the SCSI

devices that are going into the new module.

Mass Storage Module Configuration Guidelines

The following are guidelines on how to configure the mass storage module. The guidelines are divided

into two groups. The first group applies to all considerations of installing mass storage devices in the

mass storage module. If a CD–ROM drive is to be installed in the mass storage module, the second group

of guidelines also applies.

All Mass Storage Module Configurations

Ensure all the drives have their SCSI ID jumpers set prior to installation.

Attach the power and SCSI cable to the device before attaching the device to the

module.

A maximum of two fast wide devices and two single–ended devices can go into

the mass storage module

Mass Storage Module Configurations With CD–ROM Drive

Observe the guidelines stated above along with the following guidelines

A CD–ROM can only be put in the position diagonally opposite the F/W cable

entry into the mass storage module.

If a fast wide hard disk is located behind the CD–ROM drive, it must be turned

90 degrees, with the cable connectors toward the center of the mass storage mod-

ule, to allow proper clearances.

A DDS Tape drive or Floppy drive can only be positioned next to the CD–ROM.

Mass Storage Device Configurations

The following shows the positions of single–ended and fast wide mass storage devices in the mass stor-

age module.

Depending on your system, the entry point of the FW SCSI cable is at the front or the rear of the mass

storage module. Figure 2 shows the entry of the FW SCSI cable at the rear of the mass storage module

(Model 748). Figure 3 shows the entry of the FW SCSI cable at the front of the mass storage module

(TELEPACE).

Before performing this upgrade procedure, observe the following precautions:

1. Please refer to your system’s Owner’

s Guide

for the procedures to power off the system.

2. Unplug the system unit power cord and the power cords of any peripheral devices from the

power source

3. Unplug the system unit power cord from the power connector at the back of the power

supply.

WARNING: Failure to properly shut down and remove power from the system may create

a personal hazard, or may result in hardware damage or data corruption.

Remove the Existing Mass Storage Module

To remove the existing mass storage module follow these steps (See Figure 3):

CAUTION: Use care when handling the mass storage module. The mass storage

module can be heavy and awkwardly balanced.

1. Disconnect the SCSI interface cables connected to the mass storage module.

2. Unscrew both mass storage module handle screws until they pop out.

3. Pulling on the handles, slide the mass storage module out of the chassis.

4. Disconnect the DC power cables connected to the mass storage devices.

5. Disconnect the SCSI cables connected to the mass storage devices.

Installing Devices in the New Mass Storage Module

Follow these steps to install the mass storage devices in the new mass storage module. Figure 4 shows

the cabling scheme for the new mass storage module.

1. Remove the mass storage devices from the old mass storage module.

2. Install the mass storage devices into the new mass storage module. Refer to the Mass Storage

Module Configuration Guidelines for the configurations of mass storage devices allowed.

Figure 4 Mass Storage Module Cabling

CAUTION: The new mass storage module has a power cable, single–ended SCSI

cable and a fast wide SCSI cable. Be sure that the cables are secured to

their connectors on the drives and not pinched or pulled too tight before

installing the mass storage module back into the chassis.

3. Attach the mass storage devices to the appropriate slotted mounting holes in the new mass

storage module as shown in Figure 5.
