GeneralDescription

The StorCase Technology Data Express® DE75i-A66 is a removable low-profile drive
carrier and receiving frame. The DE75i-A66 is designed to provide durable and reliable
mounting for one (1) 3.5 low profile Ultra ATA/66 drive within a 5.25" half-height
peripheral slot (Figure 2). It is downward compatible with earlier technology AT/IDE
drives.

The DE75i-A66 allows the carrier unit and installed drive to be removed and transported to
another DE75i-A66 equipped computer, and also provides the ability to secure sensitive
data by removing and storing the carrier/drive safely for future use.

NOTE: For Ultra ATA/66 (66MByte/sec) operation, an Ultra ATA/66 controller and hard

ReceivingFrameFrontPanel

(Figure 3)

 The Key Lock/Drive Power Switch performs three functions. The key lock

assures proper seating of the drive carrier within the receiving frame, turns
power to the drive carrier on and off, and prevents unauthorized removal or
installation of the carrier. For the computer to access data on the DE75i-A66
drive, the key must be turned counterclockwise to the locked position.

 The Unit Number Indicator displays the physical address of the DE75i-A66

drive carrier when the carrier is Installed and Locked in the receiving frame or

Removed from the receiving frame. If the drive carrier is Installed but Not
Locked , a "u" will be displayed. The unit number is selected by means of the

unit select switch located inside the receiving frame using a special alignment
tool supplied with the DE75i-A66. This procedure is explained later during the
installation process.

 The Activity Indicator is a small dot next to the Unit Number which illuminates

to show when the host computer is accessing the data on the DE75i-A66
carrier.

DE75i-A66INSTALLATION

InstallingtheDriveinto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 panel

(bezel), it must be removed before installing the drive into the drive carrier.

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

drive designation for the DE75i-A66 unit:
 Method 1: Use the factory-installed jumper on your IDE drive - In

most cases, the drive will be factory-configured as a Master Ultra ATA/66 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 Ultra ATA/66 drive to Slave. This can be done by
changing the jumper on the Ultra ATA/66 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 JP3 and/or JP4 on the drive
carrier circuit board - The Master/Slave drive selection is set by both a hard-

wire connection between the drive and the drive carrier circuit board and
jumper(s) JP4 configuration on the receiving frame motherboard. This method
requires the fabrication of a cable wire (not provided). Refer to the section

below to configure the drive carrier circuit board and receiving frame
using this method.

Configuring the Drive Carrier Circuit Board (Method 2)

When configuring the 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.

NOTE: For dual, interchangeable drive configuration, the two drives must be

StorCase Technology Inc. DE75i-A66 User's Guide - Rev. A00

of the same make and model.

Installation 7

The appropriate pins on the drive must be connected to JP3 and/or JP4 on the carrier
board. These connections are required to set the Master/Slave configurations of the
installed drive. Figure 5 illustrates the Drive Carrier Circuit Board.

Figure 5: DE75i-A66 Drive Carrier Circuit Board

The JP3 and JP4 connectors have 3 pins each:

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

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

Pin 3 may optionally be connected to the "Active" signal of the drive. This signal

indicates whether a Slave D: drive is present or not.

controls the level of the drive activity indicator light on the front panel of the
receiving frame. 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 DE75i-A66 receiving frame. A connection to Pin 3 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).

8 Installation

Figure 6: Typical Ultra ATA/66 Master/Slave Drive Connections

Typical Ultra ATA/66 drive pin positions are shown in Figure 6. Remove and save all
jumpers. Install a wire (not provided) connecting the appropriate drive pins to the
appropriate JP3 and JP4 pins as shown in Figure 6. Refer to the drive manufacturer's
documentation for further information.

Once the Master/Slave configuration on the drive carrier circuit board is complete, the JP4
jumper(s) on the receiving frame motherboard must be configured as shown in Figure 8.

Installation

1. Attach the I/O cable on the drive carrier circuit board to the drive. Refer to
Figure 7 for an illustration of the installation process.

2. Attach the 4-pin power cable on the drive carrier circuit board to the drive.
If you are installing only one drive carrier, skip to Step 4.

3. For Method 2 Users:
If a Master/Slave cable was fabricated as outlined in the previous section,
install it now between the appropriate drive pins and connectors JP3 and
JP4 on the drive carrier circuit board. See Figure 6 for typical Ultra ATA/66
Master/Slave drive connections. Also refer to the documentation that
accompanied the drive for more specific information.

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 key 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.

Your key is now attached to the key lock
mechanism.
