Introduction 3

GeneralDescription

The StorCase Technology Data Express® DE200 (P/N S20A108) is composed of a receiving
frame which supports most 68-pin SCSI Ultra160 interfaces and fits within a 5.25" half-height
peripheral slot (Figure 2). This 16-bit I/O can support up to 160MB/sec transfer rates. The
receiving frame contains one (1) removable drive carrier designed to provide durable and
reliable mounting for one (1) 3.5" form factor, SCSI Wide, Wide Ultra, Wide Ultra2 or Wide
Ultra160 drive.

The S20A108 allows a drive to be removed and transported to another S20A108-equipped
computer or expansion chassis, and also provides the ability to secure sensitive data by
removing and storing the drive safely for future use.

The DE200 was specifically designed for use in high shock and vibration environments (e.g.
aircraft) which may also have non-PVC material requirements. The DE200 is equipped with
manual lockdown thumbscrews to secure the drive carrier within the receiving frame.

NOTES: The S20A108 carrier supports most 68-pin SCSI Ultra160 interfaces, except Fujitsu

Alegro 6 10K RPM drives (these drives have different spacing between the 68-pin
and DC power connectors and will not mate with the drive carrier board).

For SCSI Ultra160 operation, the DE200 requires Ultra160 chassis and cabling.

Adjusting the Spin Down/Up Timer

The timer for device spin down is controlled by a small selector, located in a cutout on the side
of the DE200 receiving frame as shown in Figure 10. When the key is turned to the OFF position,
and when the timer receives a NO SCSI Activity signal from the Isolator 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 disk drive to spin down is approximately 15 seconds or more.
This number can vary depending on the type of SCSI device and manufacturer (e.g. a Seagate
Barracuda may require 45 seconds). 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.

Data Express Ultra160 Isolator/Repeater Board

The Data Express Ultra160 Isolator/Repeater Board (Figure B-1) is an upgrade attachment for
the S20A108 receiving frame. This attachment provides a bus-isolating repeater function as
described below.

Bus-Isolating Hot Swap Function

The Isolator/Repeater Board provides an enhanced, bus-isolating hot swap function by
allowing the installation, removal or exchange of DE200 carriers while the computer system
is operating by monitoring and protecting the computer system and other peripheral devices
on the SCSI bus. The Isolator/Repeater Board eliminates the need to shut down the 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 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.

Repeater Function

Specifically in LVD/Single-Ended implementations, unknown system components and their
combinations may produce impedance mismatches, excessive capacitance loading and/or
noise interference within the system, potentially introducing intermittent incompatibility issues.

To minimize these unpredictable effects caused by varying system specifications, StorCase
recommends the Data Express Isolator/Repeater Board on all Ultra160 Data Express receiving
frames. This Isolator/Repeater Board provides a signal repeater function that allows the Data
Express drive enclosure to contribute to improved signal quality to and from the drive.

For more information and data, please refer to the Repeater Board Benefits and Downward
Compatibility technical papers on our web site at: http://www.storcase.com/tools

Attaching the Isolator/Repeater Board

The S20A108 may be purchased with the Isolator/Repeater Board factory-installed. If the
board has not already been attached to the S20A108 receiving frame, follow the instructions
below to add the board. Otherwise, proceed to the section "Using the Isolator Board" for usage
instructions.

Using the Isolator/Repeater Board

Carrier Removal

Follow the procedures below to remove the DE200 carrier from the receiving frame equipped
with the Isolator/Repeater Board.

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 DE200 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 Isolator Board. The unit ID number on the display will begin flashing.

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

3. As the unit ID number flashes, the board monitors the activity of the SCSI bus. When
activity is no longer present, the 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 ID 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.

Carrier Installation

Follow the procedures below to install the DE200 carrier into the receiving frame equipped with
the Isolator/Repeater Board.

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, counterclock­wise to the ON position. This locks the drive into the receiving frame and activates the
Isolator Board. The drive will begin to spin up and the unit ID number on the display will
begin flashing.

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

NOTE: No onboard termination is provided on the S20A108. External termination must

Solenoid Drive Lock

The factory-installed solenoid option prevents premature removal of the carrier and drive unit
until the target drive has fully spun down. For most disk drives, this period of time can range
from 15-40 seconds, depending on the type of drive being used (e.g. Seagate Barracuda drives
require up to 45 seconds). Refer to the drive manufacturer's documentation for specific drive
information.

The solenoid lock is controlled by a timing switch located on the side of the receiving frame.
Refer to section "Adjusting the Spin Down/Up Timer" (page 14), for information describing the
readjustment of the timer setting.

The solenoid option provides an extra step in drive protection by preventing the removal and
movement of the drive until the drive motor has fully stopped.

Units

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 to revert back to a removable key, if so desired.

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.
