GeneralDescription

The StorCaseTechnology Data Express® DE75i-SW is composed of a receiving frame with
68-pin Wide SCSI connectors and fits within a 5.25" half-height peripheral slot. The receiving
frame contains one removable drive carrier designed to provide durable and reliable mounting
for one 3.5" form factor, low-profile (up to 1" high), SCSI drive (Figure 2).

The DE75i-SW allows a drive to be removed and transported to another DE75i-SW-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: DE75i-SW Receiving Frame and Carrier

This User's Guide describes the steps required to install the StorCase Data Express
DE75i-SW 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.

ReceivingFrameFrontPanel

(Figure 3)

 Key Lock/Drive Power Switch (Figure 3) - This key switch 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-SW drive, the key must be turned counter­clockwise to the locked position. The key can be configured as either fixed or
removable as shown in Appendix C.

 Unit ID Number Indicator (Figures 3 & 4) - This LED displays the physical address

of the DE75i-SW device carrier if the carrier is installed and locked in the receiving
frame or if the carrier is removed from the receiving frame. If the carrier is installed
but not locked in the receiving frame, a "u" will be displayed to indicate an unlocked
condition. The unit ID number is selected by means of the unit ID select switch inside
the receiving frame using a special alignment tool supplied with the DE75i-SW (see
Figure 10).

 The Activity Indicator (Figures 3 & 4) - A small dot next to the unit ID number

illuminates to indicate when the host computer is accessing the data on the
DE75i-SW carrier. This dot will flash during communication with the host computer.

 Device Spin Down/Up Timer (Figure 3) - This timer controls the length of time that

the unit number display flashes during device spin down/up, providing a visual
indication of drive activity. Refer to Figure B-3 for switch settings.

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 to install is equipped with a plastic front bezel,

remove it.

3. SCSI Drive Termination: Disable or remove the termination resistor packs

from the drive. Termination is performed by an external terminator in the
DE75i-SW receiving frame (Figure 5). Refer to the documentation provided by
the drive manufacturer for the location of these terminators or jumpers.

4. SCSI Drive ID Select Jumpers: Locate the SCSI ID select jumper positions on

the drive, and remove any jumper plugs in this area. The SCSI ID cable will be
installed into this section of the drive (Figure 6).

5. SCSI ID Cable: The DE75i-SW carrier is supplied with one (1) 5-wire cable. This

cable carries the SCSI ID signal between the drive and the carrier. The signal
is then transferred to/from the receiving frame via the carrier and receiving frame
mating connectors. The ID cable permits unit ID selection via a small switch
located on the inside of the receiving frame (Figure 10). The cable is designed
to connect to drives with 2mm ID select connectors. Attach the five (5)
connectors from the carrier SCSI unit ID cable to the appropriate drive pins (Figure

7).

The unit ID cable contains black, brown, red, orange, and yellow wires. The
black wire plugs into the drive pin used to select ID0, the brown wire plugs into
the drive pin for ID1, the red wire plugs into the drive pin for ID2, and the orange
wire connects to ID3. Most drive manufacturers label these pins as ID0, ID1, ID2,
and ID3, or similar identification. The yellow wire plugs into the drive activity
LED pin.

Drives use a row of pins to provide ground to the ID signals. This row of pins
is not used for the DE75i-SW installation. One end of the unit ID cable connects
to the signal row of ID pins on the drive. The other end of this cable attaches
to the ID select connector on the inside of the carrier (Figures 6 & 7). Refer to
the drive manufacturer's documentation for more information.

DE75i-SW User's Guide - Rev. A01 StorCase Technology, Inc.

Installation

1. Attach the I/O cable from the DE75i-SW carrier board to the drive (Figure 6).

2. Attach the 4-pin power cable from the carrier board to the drive (Figure 6).

3. Install the 5-pin ID select cable into the carrier board connector (Figure 7).

4. Carefully insert the drive into the carrier at an angle, cable-end first. Make sure
that none of the cables are pinched. Lower the front of the drive carefully
into place. Fasten the drive into the carrier with four (4) #6-32 Phillips Flat Hd.
screws provided.

5. Attach the provided drive cover with two (2) #6-32 Phillips Flat Hd. screws.

TYPICAL 2MM DRIVE ID PIN CONFIGURATION

Figure 7 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins. In
most cases, the drive manufacturer labels each pair of SCSI ID select pins in their significant
bit order (0, 1, 2, 3 as shown in Figure 7). In other cases, the manufacturer does not label
these pins in their significant bit order, but instead, assigns pin numbers only. In any case,
all odd numbered pins or all even numbered pins will be the signal row. The wires on the wire
harness connect to the positive pin (or signal pins) on the drive. Refer to the device
manufacturer's documentation for additional pin numbering and jumper option information.

Attach the ID select cable to the drive using the 2mm connectors. Align the ID0 pin with the
black wire. Attach the other end of the ID select cable to the ID select connector located on
the carrier board, inside the carrier. Refer to the manufacturers documentation to disable
termination on the drive.

4. With the drive carrier locked into place inside the receiving frame, install the DE75i-SW
receiving frame into the drive opening in the computer or expansion chassis. Use the
appropriate guides to position the DE75i-SW, and fasten it into place with four (4)
#6-32 Phillips screws provided. Figure 9 illustrates the location of the mounting holes.
Mounting holes are provided on each side and the bottom of the receiving frame to
accommodate a variety of mounting configurations. Use the mounting holes which best
suit the computer or expansion chassis configuration.

Figure 9: Receiving Frame Mounting Holes

5. Adjust the front of the receiving frame so the carrier slides freely in and out on the
receiving frame guides. The position of adjoining peripheral units may require
adjustment.

6. To connect a drive to a remote activity LED in the computer system or expansion chassis,
connect the appropriate cable(s) to the receiving frame motherboard option Pins 11 &
12 as shown in Figure 5.

7. Connect the I/O cable from the host adapter to the receiving frame. The Pin 1 indicator
on the cable must be properly aligned. Refer to Figure 5 for the correct Pin 1 location.

8. When installing the DE75i-SW into a computer system, make sure that only the last SCSI
device is terminated. If the DE75i-SW is at the end of a daisy chain, the receiving frame
termination must be enabled by removing the appropriate jumper. If the
DE75i-SW is in the middle of a daisy chain, termination should be disabled (factory­installed jumper) at option Pins 9 and 10 (Figure 8).

In most cases, if installing the DE75i-SW into an external expansion chassis, the factory
installed jumper on option Pins 9 and 10 (disable termination) should be left in place.
Termination will be handled by an external terminator on the expansion chassis.

9. Connect the power cable from the DC power supply in the computer or expansion
chassis to the power connector on the DE75i-SW receiving frame. Refer to Figure 5
for the receiving frame power connector location.

StorCase Technology, Inc. DE75i-SW User's Guide - Rev. A01

Installation 13

10. Replace any expansion boards that may have been removed earlier. Replace the
system cover according to the manufacturers instructions.

11. Reconnect any system or peripheral cables removed earlier.

12. If the DE75i-SW has been installed into an external expansion chassis, connect the
SCSI and power cables to the chassis. If the expansion chassis is at the end of a
daisy chain, make certain that it is properly terminated. Refer to the computer system
and expansion chassis manuals for information on how to do this. Turn on the
expansion chassis power before turning on the computer system power.

13. Turn ON power to the computer. If the installation has been successful, and all cables
have been properly attached, the system should boot normally. Although the
computer may not recognize the DE75i-SW yet, the appropriate front panel LED
indicators on the DE75i-SW should illuminate. If the system does not boot properly,
there could be a SCSI ID conflict. Refer to the following section Selecting the Unit

Number.

NOTE: The lock on the DE75i-SW receiving frame functions as a lock and a DC power

switch for the carrier unit. The lock must be engaged (turned
counterclockwise) in order to supply power to the carrier and installed drive
unit.

14. The new drive may need to be formatted or initialized prior to use with the operating

system and applications software. Additionally, an appropriate driver may need to
installed for the host controller to recognize the newly installed device. Refer to the
drive and/or computer manufacturer's documentation for formatting information.
Refer to the host controller instructions for driver information.

SelectingtheUnitNumber

Each SCSI device on the computer system requires a separate SCSI ID number.

16-bit SCSI interface protocol permits 16 (0-15) unique SCSI ID numbers. Usually, ID7 is
reserved for the host controller. If the computer system has any internal or external SCSI
devices, some ID numbers may already be reserved. For instance, if the computer system
is already equipped with an internal SCSI hard drive, the drive may be designated as SCSI
device "0". Refer to the computer system documentation for additional information.

1. Verify that power is turned on to the DE75i-SW receiving frame by turning on the
computer or external expansion chassis. A number should appear in the unit ID display
window if the carrier is locked into place.

2. Unlock the DE75i-SW carrier from the receiving frame. The unit ID number will begin
flashing, indicating that the drive is spinning down. DO NOT REMOVE THE CARRIER
FROM THE RECEIVING FRAME WHILE THE UNIT ID NUMBER IS FLASHING. The length
of time that the unit ID number flashes is controlled by a small timing switch located on
the side of the receiving frame. Refer to Appendix B for information on adjusting the
timer (Figure B-3).

Appendix B - Factory-Installed Options

Hot Swap Board

The DE75 SCSI Hot Swap Board allows the installation, removal or exchange of DE75i-SW
carriers while your computer system is operating by monitoring and protecting the computer
system and other peripheral devices on the SCSI Bus. The Hot Swap option eliminates the
need to shut down your system when adding or removing a SCSI device by performing two
functions:

1. Delays power up/down of the drive until the time period between SCSI bus cycles.
This prevents the interruption of any SCSI bus activity being done by other devices
on the bus.

2. Prevents drive power sequencing from generating noise on the SCSI bus, thus
preventing data transfer corruption on other devices.

NOTE: Although the Hot Swap Board permits the hot swapping of devices on the

SCSI Bus, the system software may not recognize the newly installed or
removed device. Most systems scan the SCSI Bus at start-up. If the
system software does not support hot swapping, there are two
alternatives:

1. Purchase or locate third party software that scans the SCSI Bus. It is readily
available for most systems.

2. Reboot the system. This will force the system to rescan the SCSI Bus.

Attaching the Hot Swap Board

The DE75 may be purchased with the Hot Swap option factory-installed. If the Hot Swap Board
has not already been attached to the DE75i-SW receiving frame, follow the instructions below
to add the Hot Swap Board. Otherwise, proceed to the section "Using the Hot Swap Board"
for usage instructions.

1. Remove the jumper on the receiving frame motherboard option Pins 21 and 22. Option
jumper at Pins 9 & 10 must be installed (default setting) to disable on-board termination
at the receiving frame motherboard (Figure 5). The Hot Swap Board (Figure B-2),
will control onboard termination. Removing jumper JP1 will enable termination.

2. Carefully align the connectors of the Hot Swap Board with the connectors on the
receiving frame motherboard and gently push the Hot Swap Board into position.
Make certain that all connectors are properly mated.

3. Attach the Hot Swap Board to the receiving frame stand-offs with the two (2)
provided screws (Figure B-1).

20 Appendix B - Factory-Installed Options

Figure B-1: Attaching the Hot Swap Board

Jumper Options

Most jumper options are configurable via the receiving frame motherboard (Figure 7). The Hot
Swap Board provides one configurable jumper, JP1 (Figure B-2). When installed (factory
default), this jumper disables onboard termination. If the DE75i-SW is physically located at the
end of a SCSI daisy chain, remove this jumper to enable termination.

Using the Hot Swap Board

Carrier Removal

Follow the procedures below to remove the DE75i-SW carrier from the receiving frame
equipped with the Hot Swap option.

1. Verify that the drive is not active. If the system is on a network, make certain other
users are not accessing the target drive, then disable it from the network. Dismount
the drive.

2. Turn the key lock mechanism (located on the front of the receiving frame), clockwise
to the OFF position. This unlocks the drive from the receiving frame and activates the
Hot Swap Board. The unit number on the display will begin flashing.

3. As the unit number flashes, the Hot Swap Board monitors the activity of the SCSI bus.
When activity is no longer present, the Hot Swap Board will remove power from the
drive and then remove the device from the SCSI Bus. The unit number will continue
to flash during this period.

4. After a short length of time the unit display will turn from a flashing unit number to a
steady u, indicating that the device is powered down, unlocked and ready to be
removed from the receiving frame.

the carrier is physically unlocked, the drive requires a minimum of 15
seconds to spin down and is subject to vibration and possible damage
during this period.

22 Appendix B - Factory-Installed Options

NOTE: The timer for device spin down is controlled by a small selector, located in a cutout

on the side of the DE75i-SW receiving frame as shown in Figure B-3. When the
key is turned to the OFF position, and when the timer receives a "No SCSI Activity"
signal from the Hot Swap Board, it waits the specified delay time before displaying
a u on the front panel of the receiving frame. The amount of time required for
a drive to spin down is approximately 15 seconds or more. This number can vary
depending on the type of SCSI device and manufacturer (some drives may require
45 seconds or more). The factory configuration is set for 20 seconds. A different
delay time may be selected with the provided alignment tool. Refer to the SCSI
device manufacturers manual for more information on required device spin down
time.

Carrier Installation

Follow the procedures below to install the DE75i-SW Carrier into the receiving frame equipped
with the Hot Swap option.

1. Install the carrier into the receiving frame. A "u" will be present on the front panel,
indicating that the carrier is in an unlocked condition.

2. Turn the key lock mechanism, located on the front of the receiving frame, counter
clockwise to the ON position. This locks the drive into the receiving frame and activates
the Hot Swap Board. The drive will begin to spin up and the unit number on the display
will begin flashing.

3. After a short length of time the unit display will stop flashing, indicating that the device
is ready to be used.

Appendix C - 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.
