Introduction 3

GeneralDescription

The StorCase Technology Data Express® DE90i-A is a removable lightweight drive carrier and
receiving frame designed to provide durable and reliable mounting for one (1) 3.5 AT/IDE drive
within a 5.25" half-height peripheral slot (Figure 1).

The DE90i-A allows a drive to be removed and transported to another DE90i-A-equipped
computer or expansion chassis, and also provides the ability to secure sensitive data by
removing and storing the drive safely for future use.

Figure 2: DE90i-A Receiving Frame and Carrier

This User's Guide describes the steps required to install the StorCase Data Express
(DE90i-A) removable enclosure inside a computer peripheral bay or external expansion
chassis. This guide supplements documentation provided with the host computer system,
operating system, and the drive to be installed within the Data Express carrier.

4 Introduction

ReceivingFrameFrontPanel

(Figure 3)

 The Key Lock/Drive Power Switch performs three (3) functions. The key lock

assures proper seating of the device carrier within the receiving frame, turns power
to the device carrier on and off, and prevents unauthorized removal or installation
of the carrier. For the computer to access data on the DE90i-A disk drive, the key
must be turned counterclockwise to the locked position.

The key can be attached (optional) to the locking mechanism as shown in Appendix
B.

 Front Panel Indicator LEDs (Figure 2) Indicator LEDs on the DE90i-A receiving

frame front panel provide important operating information based on the following
conditions:

Table 1: Receiving Frame Front Panel Indicator Conditions

CONDITION LED A LED B LED C

Indicators A and B will alternately blink during the 10 second drive spin down/up period after the key has been turned on or off.

When the carrier has been unlocked from the receiving frame, these lights will flash as the drive spins down. DO NOT
REMOVE THE CARRIER FROM THE RECEIVING FRAME DURING THIS PERIOD to prevent possible drive damage.

INSTALLATION

InstallingtheDriveintheCarrier

Preparation

While performing the steps in this section, work on a soft surface to prevent excessive shock
to the drive being installed. Also refer to the manufacturer's documentation provided with the

drive.

NOTE: A #2 Phillips screwdriver will be required during this procedure.

1. Remove the drive from its protective packaging.

2. Plastic Drive Bezel: If the drive came equipped with a plastic front bezel, it

must be removed.

3. Master/Slave Drive Selection: There are two (2) ways to set the Master/

Slave drive designation for your DE90i-A unit:

 Method 1: Use the factory-installed jumper on your IDE drive -

most cases, the drive will be factory-configured as a Master IDE drive using
a jumper plug on the drive itself. No configuration changes are required. For
multiple drive configurations, it is necessary to set the first IDE drive as Master
and the second IDE drive to Slave. This can be done by changing the jumper
on the IDE drive itself (refer to your drive manufacturer documentation). This
method requires no additional configuration of the drive carrier circuit board.
Skip the Method 2 section below and continue with the "Installation" section.

 Method 2: Use the hard-wire connector J3 on the drive

circuit board - The Master/Slave drive selection can also be set by the
receiving frame using Jumper J4A located on the rear panel. This requires the
fabrication of a cable wire (not provided). Refer to the section below to

configure the drive carrier circuit board using the Connector J3.

Configuring the Drive Carrier Circuit Board (Method 2)

When configuring dual drives for interchangeable Master/Slave assignment, it is necessary
to emulate the Master and Slave drive jumpers and the specific drive's signal polarity definition
of Master and Slave.

The appropriate signals from the drive must be connected to J3 on the carrier board. These
signals are used to enable the functions of the unit selection, as well as the front panel display,
and drive activity indicator light. A 3-pin wire wrap connector is provided to enable fabrication
of a cable (cable not included) from the AT/IDE drive to the DE90i-A carrier circuit board. Figure

Configuring Connector J3

The connector J3 has three (3) pins:

J3 Pin 1 should be connected to the Master signal of the disk drive. This signal

J3 Pin 2 may be connected to the Slave/Slave Present signal of the drive. This signal

J3 Pin 3 may be connected to the "Active" signal of the drive (optional). This signal

controls the level of the drive activity indicator light on the front panel of the
receiving frame.

Installation 9

The receiving frame circuit board is designed to route the drive's -HOST SLV/ACT signal
(drive activity) to the activity indicator light on the front panel of the DE90i-A receiving
frame. A connection to J3 Pin 3 (on the carrier board) should only be made if the drive
does not support this -HOST SLV/ACT signal on Pin 39 of the interface connector (check
the documentation that accompanied the drive and controller). If this J3 Pin 3 connection
is made, move jumper JP39 on the receiving frame from the "A" to the "B" position.

Three (3) Drive Type Jumpers, W1, W2, and W3 are available to control the signal levels at
J3, Pins 1 & 2.

Table 2 shows the signal levels on J3 Pin 1 and Pin 2 for different W1, W2, and W3 jumper
settings. Connections to J3 Pin 1 should be made with signals from the drive that refer to Master,
while connections to J3 Pin 2 should be made with signals from the drive that refer to Slave.

Installation

1. Attach the I/O cable from the drive carrier circuit board of the DE90i-A to the drive
(Figure 7).

2. Attach the DC power cable from the rear distribution board to the drive (Figure

7).

3. For Method 2 Users (as defined on page 7):
If the 3-pin Master/Slave select cable was created as outlined in the previous
section, install it now into the connector on the drive carrier circuit board. See
Figure 6 for a typical AT/IDE connection. Also refer to the documentation that
accompanied the drive for more specific information.

4. Carefully insert the drive into the drive carrier at an angle, cable-end first. Make
sure none of the cables are pinched. Lower the front of the drive carefully
into place. Fasten the drive into the carrier with four (4) of the eight (8) screws
provided as shown in Figure 7.

5. Install the provided cable cover.

Appendix B - Attaching the ON/OFF Key

The following information will provide the necessary steps to attach the ON/OFF key to the
key lock mechanism so that it is non-removable, preventing accidental key loss. The procedure
can be reversed at a later date to revert back to a removable key.

1. Make certain power is OFF to the receiving frame.

Locate the rectangular shaped key lock mecha­nism access hole on the inside of the receiving
frame. Note that the pawl is in an upright position.

Insert the key into the lock.

2. Rotate the key 90 degrees counterclockwise so
that the pawl is visible in the access hole as
shown in the figure at left.

3. Using the provided alignment tool, unscrew and
remove the pawl from the access hole.

4. Rotate the key 180 degrees clockwise.

5. Reinstall the pawl into the access hole with the
alignment tool.

The key lock has now been reconfigured.
