GeneralDescription

The StorCase Technology Data Express® DE75i-SWC 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 a removable drive carrier designed to provide durable and
reliable mounting for one (1) 3.5" form factor, low-profile (up to 1" high) SCSI drive. The
DE75i-SWC is specifically designed for 80-pin Single Connector Attachment (SCA) SCSI
drives (Figure 2).

The DE75i-SWC allows a drive to be removed and transported to another DE75i-SWC­equipped computer or expansion chassis, and also provides the ability to secure sensitive
data by removing and storing the drive safely for future use.

4 Introduction

ReceivingFrameFrontPanel

(Refer to 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
DE75i-SWC 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 C.

 The Unit Number Indicator (also refer to Figure 4) displays the physical

address of the DE75i-SWC 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 number is selected by means of the
unit select switch inside the receiving frame using a special alignment tool
supplied with the DE75i-SWC.

 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-SWC
carrier. This dot will flash during communication with the host computer.

Hot Swap Board

The DE75 SCSI Hot Swap Board (part number DX75-SWC/H) allows the installation,
removal or exchange of DE75i-SWC 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.

Please note that, whereas UNIX and Apple based systems provide mount/dismount drive
commands, most PC systems do not provide such a feature. When using one of these
operating systems, it may be necessary to reboot the computer after adding or changing
a drive. This reboot activity will force the SCSI host adapter to rescan its SCSI bus for
physically attached drives, and will then be able to access the new or changed drive.

Attaching the Hot Swap Board

The DE75i-SWC may be purchased with the Hot Swap option factory-installed. If the Hot
Swap Board has not already been attached to the DE75i-SWC 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 and 10 must be installed (default setting) to disable on­board 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 (Refer to the next section "Jumper Options").

NOTE: Save these jumper(s)! These jumper(s) are required when the Hot

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).

Appendix B - Factory-Installed Options 19

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-SWC will be
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-SWC 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 DE75i-SWC 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.

StorCase Technology Inc. DE75i-SWC User's Guide - Rev. B00

Appendix B - Factory-Installed Options 21

WARNING: Be careful not to remove or disturb the carrier unit at this point.

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.

Although 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.

Carrier Installation

Follow the procedures below to install the DE75i-SWC 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.

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.
