Introduction 3

GeneralDescription

The StorCase Technology Data Express® DE300i-SWC is composed of a receiving frame
with 68-pin SCSI Wide connectors and fits within 5.25" full-height peripheral slots. The
receiving frame contains three (3) removable drive carriers designed to provide durable
and reliable mounting for three (3) 3.5" form factor x 1" high SCSI drives. The DE300i­SWC is specifically designed for Single Connector Attachment (SCA) SCSI drives (Figure

2).

The DE300i-SWC allows a drive to be removed and transported to another DE300i-SWC­equipped computer or expansion chassis, and also provides the ability to secure sensitive
data by removing and storing the drive safely for future use. The DE300i-SWC is
particularly well suited for RAID configurations, combining wide receiving frame I/O
connectors with three (3) removable single connect (SCA) drive carriers.

This User's Guide describes the steps required to install the StorCase Data Express
(DE300i-SWC) 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 DE300i-SWC
carrier.

(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
DE300i-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 (Figure 4) displays the physical address of the

DE300i-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 ID number is selected by means of the
unit select switch inside the receiving frame using a special alignment tool
supplied with the DE300i-SWC.

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

illuminates to show when the host computer is accessing the data on the
DE300i-SWC carrier. This dot will flash during communication with the host
computer.

 Device Spin Down/Up Timer This feature allows the receiving frame unit

number display to provide a visual indication of drive spin down/up activity. A
small timing switch located on the side of the receiving frame allows the
operator to adjust the timer to match the specific drive manufacturer's specifica­tions (Figure B-3).

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 as shown in Figure 5. Connect J3A, J3B, and J3C Pins 11 and
12 to a remote activity LED.

7. Connect the I/O cables 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. Make sure that only the last SCSI device is terminated. If the DE300i-SWC is
at the end of a daisy chain, the receiving frame termination for the last
device must be enabled by removing the appropriate jumper. If the
DE300i-SWC is in the middle of a daisy chain, termination should be disabled
(jumper installed, factory setting) at J3A, J3B, and J3C, Pins 9 and 10
(Figure 7).

12 Installation

StorCase Technology Inc. DE300i-SWC User's Guide - Rev. A00

9. Connect the power cable from the DC power supply in the computer or
expansion chassis to the power connector on the DE300i-SWC receiving
frame. Refer to Figure 5 for the DE300i-SWC receiving frame power
connector location.

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. 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 DE300i-SWC yet, the
appropriate front panel LED indicators on the DE300i-SWC should illuminate.

NOTE: The lock on the DE300i-SWC 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.

13. The new drives may need to be formatted or initialized prior to use with the
operating system and applications software. Refer to the drive and/or
computer manufacturer's documentation for formatting information.

SelectingtheUnitID Number

1. Verify that power is turned on to the DE300i-SWC receiving frame by
turning on the computer or external expansion chassis. Numbers should
appear in the unit display windows if the carriers are locked into place.

2. Unlock the DE300i-SWC drive carrier and remove it from the receiving
frame. A "u" will be displayed initially when the unit is unlocked but will
return to a SCSI ID number when the carrier is removed from the receiving
frame.

WARNING: Unlocking the carrier unit switches DC power off to the

drive. Since disk drives require a short amount of time to
spin down, allow about 15 seconds before pulling the
carrier unit out of the receiving frame to avoid possible
damage to the drive.

3. Use the alignment tool supplied with the DE300i-SWC to select the ID
number of the disk drive. Refer to Figure 9 for the location of the Unit ID
Select Switch inside the receiving frame.

DE300 Hot Swap Board

The DE300 SCSI Hot Swap Board (part number DX300-SWC/H) allows the installation,
removal or exchange of DE300i-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 DE300i-SWC may be purchased with the Hot Swap option factory-installed. If the Hot
Swap Board has not already been attached to the DE300i-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 two (2) Phillips head machine screws from the receiving frame
motherboard and set aside (Figure B-1).

2. Remove jumpers on the receiving frame motherboard J3A, J3B, and J3C Pins 21
and 22 (Figure 5). Option jumpers 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 jumpers JTA, JTB, or JTC, will enable termination at the corresponding
drive.

NOTE: Save these jumpers! These jumpers are required when the Hot Swap

Board is not installed.

3. Attach the two (2) provided stand-offs into the receiving frame motherboard
holes in place of the two removed screws. 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.

4. Attach the Hot Swap Board to the receiving frame motherboard by using the two
screws removed earlier and insert them through the Hot Swap Board into the
stand-offs.

Jumper Options

Most jumper options are configurable via the receiving frame motherboard (Figure 7). The
Hot Swap Board provides three (3) configurable jumpers, DTA, DTB, and DTC (Figure B-

2). When installed (factory default), these jumpers disable onboard termination at drives
A, B, and C, respectively. If a DE300 drive will be physically located at the end of a SCSI
daisy chain, remove the appropriate jumper to enable termination.

Using the Hot Swap Board

Carrier Removal

Follow the procedures below to remove the DE300i-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 DE300 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 ID number on the display will begin
flashing.

Appendix B - Factory-Installed Options 21

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

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.

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 ID 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.

Carrier Installation

Follow the procedures below to install the DE300i-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.

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.

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.
